Utilization of Pineapple Fruit Waste in Greener Alternative Agents for Thai Silk Pretreatment and Acid Dyeing Wastewater Treatment.

Pineapple, extensively cultivated in tropical and subtropical regions, contains bromelain, a protein-digesting enzyme that is highly valued in the food and beverage industries. Pineapple residues from food processing retain these enzymes and can be repurposed for silk processing. This research utilized Smooth Cayenne pineapple juice as a degumming agent and its pulp as an adsorbent for dyeing effluent treatment. Pineapple juice, containing bromelain with a protease activity of 16.40 µg/mL·min, effectively removed 22% of sericin from raw silk using a liquid ratio of 30:1 at pH 7 and 60 °C for 60 min. Unlike alkaline degumming, which weakened silk fibers (maximum load 6.18 ± 1.56 N), pineapple juice-treated silk retained higher strength (maximum load 7.80 ± 1.32 N), offering a gentler alternative. The remaining pineapple pulp, after juice extraction, was processed into a porous adsorbent with a surface area of 3.63 m2/g and a pore size of 6.15 nm. This material absorbed acid dyes effectively at pH 5, the normal pH used in the acid dyeing of silk. Valorizing pineapple residues reduces chemical use, energy consumption, and environmental impact while lowering production costs and enhancing local resources.

Evaluation of Sericin/Polyvinyl Alcohol Mixtures for Developing Porous and Stable Structures.

Fibrous by-products, including defective or double cocoons, are obtained during silk processing. These cocoons primarily contain fibroin and sericin (SS) proteins along with minor amounts of wax and mineral salts. In conventional textile processes, SS is removed in the production of smooth, lustrous silk threads, and is typically discarded. However, SS has garnered attention for its antioxidant, antibacterial, biocompatible, and anticancer properties as well as its excellent moisture absorption, making it a promising polymer for biomedical applications. Owing to its functional groups (carboxyl, amino, and hydroxyl), SS can blend and crosslink with other polymers, thereby improving the mechanical properties of sericin-based materials. This study explored the effects of different SS/polyvinyl alcohol (PVA) ratios on porous scaffolds fabricated via freeze-drying, focusing on the mechanical stability, water absorption, and protein release in phosphate-buffered saline (PBS). The scaffold morphology revealed reduced porosity with higher SS content, while increased PVA content led to material folding and layering. A greater PVA content enhanced water absorption, mechanical properties, and thermal stability, although SS release decreased. These results demonstrate that scaffold properties can be tailored by optimizing the SS/PVA ratio to suit specific biomedical applications.

A Classification Model for Fine-Grained Silkworm Cocoon Images Based on Bilinear Pooling and Adaptive Feature Fusion

The quality of silkworm cocoons affects the quality and cost of silk processing. It is necessary to sort silkworm cocoons prior to silk production. Cocoon images consist of fine-grained images with large intra-class differences and small inter-class differences. The subtle intra-class features pose a serious challenge in accurately locating the effective areas and classifying silkworm cocoons. To improve the perception of intra-class features and the classification accuracy, this paper proposes a bilinear pooling classification model (B-Res41-ASE) based on adaptive multi-scale feature fusion and enhancement. B-Res41-ASE consists of three parts: a feature extraction module, a feature fusion module, and a feature enhancement module. Firstly, the backbone network, ResNet41, is constructed based on the bilinear pooling algorithm to extract complete cocoon features. Secondly, the adaptive spatial feature fusion module (ASFF) is introduced to fuse different semantic information to solve the problem of fine-grained information loss in the process of feature extraction. Finally, the squeeze and excitation module (SE) is used to suppress redundant information, enhance the weight of distinguishable regions, and reduce classification bias. Compared with the widely used classification network, the proposed model achieves the highest classification performance in the test set, with accuracy of 97.0% and an F1-score of 97.5%. The accuracy of B-Res41-ASE is 3.1% and 2.6% higher than that of the classification networks AlexNet and GoogLeNet, respectively, while the F1-score is 2.5% and 2.2% higher, respectively. Additionally, the accuracy of B-Res41-ASE is 1.9% and 7.7% higher than that of the Bilinear CNN and HBP, respectively, while the F1-score is 1.6% and 5.7% higher. The experimental results show that the proposed classification model without complex labelling outperforms other cocoon classification algorithms in terms of classification accuracy and robustness, providing a theoretical basis for the intelligent sorting of silkworm cocoons.

The Dawning Era of Anticancer Nanomedicines: From First Principles to Application of Silk Nanoparticles

AbstractThis review introduces nanomedicines and medical silks by addressing seminal and recent research within these fields. First, the successes of nanoparticles in improving the safety profiles and pharmacokinetic–pharmacodynamic properties are explored but also the concepts of threshold dosing and targeting of tumor‐associated macrophages. Current barriers to systemic delivery of nanomedicines are detailed and methods to overcome these barriers and increase tumor targeting are evaluated, namely: tuning the nanomedicine size and surface charge for enhanced tumor accumulation and penetration; non‐spherical nanomedicine morphologies for macrophage evasion and targeted delivery to endothelial cells; and, surface functionalization for stealth coatings and targeting receptor‐mediated endocytosis. The advantages of using silk as a nanomedicine with reference to its structure, composition, biological performance, and formulation are discussed. While batch methods for silk processing enable the formation of nano to microparticles, continuous technology can overcome bottlenecks of the deployed engineering methods such as low throughput and poor reproducibility. Finally, the chemical modification of silk using homogeneous and heterogenous chemistries is assessed within the nanomedicine context. Overall, this review covers silk nanomedicines from first principles to carrier design and on to areas of future development.

Potential therapeutic agents of Bombyx mori silk cocoon extracts from agricultural product for inhibition of skin pathogenic bacteria and free radicals.

Pathogenic bacteria are the cause of most skin diseases, but issues such as resistance and environmental degradation drive the need to research alternative treatments. It is reported that silk cocoon extract possesses antioxidant properties. During silk processing, the degumming of silk cocoons creates a byproduct that contains natural active substances. These substances were found to have inhibitory effects on bacterial growth, DNA synthesis, the pathogenesis of hemolysis, and biofilm formation. Thus, silk cocoon extracts can be used in therapeutic applications for the prevention and treatment of skin pathogenic bacterial infections. The extract of silk cocoons with pupae (SCP) and silk cocoons without pupae (SCWP) were obtained by boiling with distilled water for 9 h and 12 h, and were compared to silkworm pupae (SP) extract that was boiled for 1 h. The active compounds in the extracts, including gallic acid and quercetin, were determined using high-performance liquid chromatography (HPLC). Furthermore, the total phenolic and flavonoid content in the extracts were investigated using the Folin-Ciocalteu method and the aluminum chloride colorimetric method, respectively. To assess antioxidant activity, the extracts were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. Additionally, the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of silk extracts and phytochemical compounds were determined against skin pathogenic bacteria. This study assessed the effects of the extracts and phytochemical compounds on growth inhibition, biofilm formation, hemolysis protection, and DNA synthesis of bacteria. The HPLC characterization of the silk extracts showed gallic acid levels to be the highest, especially in SCP (8.638-31.605 mg/g extract) and SP (64.530 mg/g extract); whereas quercetin compound was only detected in SCWP (0.021-0.031 mg/g extract). The total phenolics and flavonoids in silk extracts exhibited antioxidant and antimicrobial activity. Additionally, SCP at 9 h and 12 h revealed the highest anti-bacterial activity, with the lowest MIC and MBC of 50-100 mg/mL against skin pathogenic bacteria including Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), Cutibacterium acnes and Pseudomonas aeruginosa. Hence, SCP extract and non-sericin compounds containing gallic acid and quercetin exhibited the strongest inhibition of both growth and DNA synthesis on skin pathogenic bacteria. The suppression of bacterial pathogenesis, including preformed and matured biofilms, and hemolysis activity, were also revealed in SCP extract and non-sericin compounds. The results show that the byproduct of silk processing can serve as an alternative source of natural phenolic and flavonoid antioxidants that can be used in therapeutic applications for the prevention and treatment of pathogenic bacterial skin infections.

Characterization of Recent and Historical Silks: Effects of Silk Processing on Chemical Composition and Amino Acid Racemization

ABSTRACT In this work, the influence of dyeing, mordanting and degumming techniques on the amino acid (AA) composition and the AA racemization (AAR) of (non-)mulberry silks is studied by a chiral GC-MS method. The tested dyeing and mordanting procedures as well as a pre-treatment of the silk filaments with EDTA-DMF, which enables a parallel dyestuff analysis by HPLC-DAD, do not cause any significant change in the AA composition. However, an increased proportion of e.g. (D)-Asx can be observed for some of the mordanted BM silks. Increased D/L Asx ratios can also be observed in indigo dyed silks and after an alkaline treatment at 110°C (pH > 9). Furthermore, the GC-MS method was used for the characterization of historical silk samples from finding sites in the Tarim Basin (China). The analysis of these silk fabrics reveals the presence of degraded Bombyx silk with significantly increased D/L Val, D/L Glx and D/L Asx ratios. Including microscopic and spectroscopic investigations, the results of this multi-analytical approach offer insights into the silk processing techniques and raw materials used.

A Comparative Study of Drying of Muga Cocoons using Convection and Infra-red Heating Method

Background: Muga is an exclusive golden-colored silk produced by the Antheraea Assamensis silkworm species in North-east India. In the silk processing stage, drying of Muga silkworm cocoon is essential to prevent the pupa from emerging from the shell and to preserve the cocoons for a longer period (3-6 months). It is necessary to reduce the potentially harmful high moisture level in the cocoon shell and pupa body to an optimum or safe level of moisture content (6-12%). In India, the natural sun drying method is the most common method to preserve Muga cocoons for a longer period. Considerably losses may occur using the sun-drying method due to various effects such as rodents, insects, rain, microorganisms, excessive temperature, etc. To address this issue the study was conducted to improve the quality of Muga silk yield using a comparative study between Convection and IR heating methods for cocoon drying. Methods: In this study, Muga cocoons were dried properly at optimum temperature (50-100°C) to obtain a safe moisture level for getting quality Muga silk. The drying of the Muga cocoon is processed using convection (1 kw) and Infrared (650 watts) modes of heating for the same duration of time. Muga cocoons were placed in a drying chamber initially at a high temperature (100±5°C) using both convection and Infrared heating methods separately to maintain the moisture content to an optimum level. It took approximately 75 minutes to obtain the temperature 100 from room temperature and every 15 minutes temperature measure was recorded for both methods and compared. The parameters studied were temperature, time, cocoon weight, shell weight, shell ratio and moisture content. These parameters were examined, evaluated and compared for both the Convection and IR heating methods. Result: The comparative study results indicated that the performance of the studied cocoon parameters namely temperature, cocoon weight, shell weight, shell ratio and moisture content are approximately similar for both convection and IR heating methods. Moisture content was maintained at the optimum range (6-12%) for both the convection and IR methods. The study provided a better performance using the IR heating method as compared to convection heating concerning energy consumption and safety for the same duration of time. Energy consumed by a 1 kW convection heater is 1.25 kWh, whereas energy consumption in a 650-watt IR heater is 0.8125 kWh.

More Reliable Dating of Japanese Silk Mounting Textiles for Conservation Decisions: Effects of Silk Processing on Silk Surface Morphology and Aspartic Acid Racemization

ABSTRACT Dating silk mounting textiles is important for understanding their condition and susceptibility to degradation. Amino acid racemization is a technique currently used for this purpose. The research presented here aimed to clarify when this technique is reliable and when it is not. Silk fibers taken from a cocoon and from Japanese mounting textiles were studied using optical microscopy to document surface roughness. Chiral capillary electrophoresis mass spectrometry for amino acid racemization dating (AAR), liquid chromatography mass spectrometry for dye analysis, and FTIR for analysis of sericin and other materials adhering to the silk were also used. A change from rough fiber surfaces (greater than a hundred years old) to smooth fiber surfaces (less than a hundred years) was found. This correlated with the time of the introduction of Western degumming methods in Japan. Synthetic dyes were not found on the earlier silk fibers with rough surfaces. AAR dating measurements on rough surfaced fibers with remaining sericin correlated better with the estimated age of the silk fabrics than fibers with smooth surfaces, suggesting the technique should only be used for silk fibers with rough surfaces. A screening method for fibers for AAR analysis was outlined.

Factors Influencing Properties of Spider Silk Coatings and Their Interactions within a Biological Environment.

Biomaterials are an indispensable part of biomedical research. However, although many materials display suitable application-specific properties, they provide only poor biocompatibility when implanted into a human/animal body leading to inflammation and rejection reactions. Coatings made of spider silk proteins are promising alternatives for various applications since they are biocompatible, non-toxic and anti-inflammatory. Nevertheless, the biological response toward a spider silk coating cannot be generalized. The properties of spider silk coatings are influenced by many factors, including silk source, solvent, the substrate to be coated, pre- and post-treatments and the processing technique. All these factors consequently affect the biological response of the environment and the putative application of the appropriate silk coating. Here, we summarize recently identified factors to be considered before spider silk processing as well as physicochemical characterization methods. Furthermore, we highlight important results of biological evaluations to emphasize the importance of adjustability and adaption to a specific application. Finally, we provide an experimental matrix of parameters to be considered for a specific application and a guided biological response as exemplarily tested with two different fibroblast cell lines.

Fabrication of Antheraea mylitta sericin hydrogel film via non toxic crosslinking citric acid with antioxidant properties

ABSTRACT Sericin, a water-soluble protein biopolymer, is usually discarded as a byproduct of the silk processing industries. However, in recent years the applications of sericin biomacromolecule for biomaterial fabrication have increased. The current strategy of sericin hydrogel preparation involves crosslinking with glutaraldehyde or genipin which are known to be cytotoxic and hinder/restrict the biological applications of the end product. Therefore, citric acid, a nontoxic crosslinking agent, was explored for the fabrication of Antheraea mylitta sericin hydrogel films (AmSHF) with and without Polyethylene glycol (PEG). The biophysical characterization of fabricated hydrogel films confirmed the native properties of the natural silk in the regenerated sericin, as well as the AmSHF and appearance of the peak at 1709 cm−1, which indicated crosslinking of the hydrogel films due to the formation of ester bonds resulting in nanoscale roughness of 4.29 nm and amorphous nature with a higher swelling ratio of 18.76 ± 0.058 g/g. The antioxidant nature of sericin was retained even after AmSHF formation as revealed by antioxidant assays. The AmSHF were also found to be cytocompatible and significantly increased the proliferation of NIH3T3 fibroblast cells. These results open up several possibilities for using these hydrogels as a biomaterial for wound healing and skin tissue regeneration.

Micro and nano-scale compartments guide the structural transition of silk protein monomers into silk fibers

Silk is a unique, remarkably strong biomaterial made of simple protein building blocks. To date, no synthetic method has come close to reproducing the properties of natural silk, due to the complexity and insufficient understanding of the mechanism of the silk fiber formation. Here, we use a combination of bulk analytical techniques and nanoscale analytical methods, including nano-infrared spectroscopy coupled with atomic force microscopy, to probe the structural characteristics directly, transitions, and evolution of the associated mechanical properties of silk protein species corresponding to the supramolecular phase states inside the silkworm’s silk gland. We found that the key step in silk-fiber production is the formation of nanoscale compartments that guide the structural transition of proteins from their native fold into crystalline β-sheets. Remarkably, this process is reversible. Such reversibility enables the remodeling of the final mechanical characteristics of silk materials. These results open a new route for tailoring silk processing for a wide range of new material formats by controlling the structural transitions and self-assembly of the silk protein’s supramolecular phases.

Silk Protein Composite Bioinks and Their 3D Scaffolds and In Vitro Characterization.

This paper describes the use of silk protein, including fibroin and sericin, from an alkaline solution of Ca(OH)2 for the clean degumming of silk, which is neutralized by sulfuric acid to create calcium salt precipitation. The whole sericin (WS) can not only be recycled, but completely degummed silk fibroin (SF) is also obtained in this process. The inner layers of sericin (ILS) were also prepared from the degummed silk in boiling water by 120 °C water treatment. When the three silk proteins (SPs) were individually grafted with glycidyl methacrylate (GMA), three grafted silk proteins (G-SF, G-WS, G-ILS) were obtained. After adding I2959 (a photoinitiator), the SP bioinks were prepared with phosphate buffer (PBS) and subsequently bioprinted into various SP scaffolds with a 3D network structure. The compressive strength of the SF/ILS (20%) scaffold added to G-ILS was 45% higher than that of the SF scaffold alone. The thermal decomposition temperatures of the SF/WS (10%) and SF/ILS (20%) scaffolds, mainly composed of a β-sheet structures, were 3 °C and 2 °C higher than that of the SF scaffold alone, respectively. The swelling properties and resistance to protease hydrolysis of the SP scaffolds containing sericin were improved. The bovine insulin release rates reached 61% and 56% after 5 days. The L929 cells adhered, stretched, and proliferated well on the SP composite scaffold. Thus, the SP bioinks obtained could be used to print different types of SP composite scaffolds adapted to a variety of applications, including cells, drugs, tissues, etc. The techniques described here provide potential new applications for the recycling and utilization of sericin, which is a waste product of silk processing.

Isolation and identification of protease‐producing bacteria from sludge and sediment soil around Adama, Ethiopia

Proteases are enzymes used in industries such the production and processing of detergents, food, leather, and silk. The aim of this study was to isolate and identify protease‐producing bacteria from a sludge disposal site and from sediments. Soil samples were collected separately from the selected area. Samples weighing 1 g were serially diluted and spread onto skim milk agar. A total of 16 bacteria species were isolated from the study samples. Four bacterial isolates showed high proteolytic activity and were selected for enzymatic study based on their zone of proteolysis. The isolates were identified based on biochemical tests. The results indicated that the isolated bacteria were E. coli (99.69%), Pseudomonas putrefaciens (Shewanella putrefaciens) (91.61%), Bacillus carboniphilus (92.78%), and Lysinibacillus sphaericus (98.4%). The crude protease enzymes produced by these bacterial isolates showed promising results for application in dehairing and destaining as detergent additives. Bacillus carboniphilus showed the best level of activity and was selected as the most potent protease‐producing bacteria for both dehairing and destaining ability. Soils from sludge disposal sites and sediments from around tannery wastes could be good sources from which to isolate alkaline protease‐producing bacteria.

Unravelled Dreams: Silk and the Atlantic World, 1500–1840 by Ben Marsh

Histories of individual commodities and products abound these days, but Marsh’s Unravelled Dreams differs from most of them in one important respect. Rather than spinning a tale of biological and commercial success, Marsh traces how and why silk production failed in so many different places and in so many ways in the Western Hemisphere during the early modern period. Indeed, his chronicle of serial miscalculations and disappointments involving silk brings to mind nothing so much as Beckett’s famous lines in Worstward Ho: “Ever tried. Ever failed. No matter. Try again. Fail again. Fail Better.”1On the surface, the reasons for the many attempts to develop a viable silk industry in the Americas during the early modern period are understandable. The natural fiber was highly valued and much in demand at the time, and, as Marsh demonstrates in his opening chapter, it had been cultivated and processed successfully in many parts of Afro-Eurasia after its appearance in China c. 5000 b.c.e. In hindsight, however, experimenters with silk could have proceeded with a bit more caution; myriad challenges had to be overcome merely to produce good silk, much less to do so efficiently and at a scale sufficient to create an industry.Silk is derived from the cocoons of domesticated moths classified by Linnaeus as Bombyx mori. Once moth eggs of this species hatch into larvae, they eat voraciously and continually, with a preference for the leaves of white mulberry trees. At a certain point in the growth process, the larvae enclose themselves in cocoons of raw silk, which is essentially a protein produced by their salivary glands. Silk is harvested by boiling the evolving moths inside their cocoons and then unravelling the single thread of silk from which each cocoon is made. The raw silk, which is quite delicate, then must go through an elaborate multi-stage processing sequence before it can transform into one or another variety of silk fabric. Silk processing during the early modern period occurred both at the household level on manual reels and in certain areas at larger facilities known as filatures, which often employed mechanical power of one type of another.The above description of silk production, however truncated, is sufficient to suggest the elements that comprised the complicated, entrepreneurial undertaking of silk production in the Western Hemisphere: transporting fragile moth eggs long distances to places where white mulberry trees flourished and finding/acquiring, and then retaining, skilled workers who could tend to the worms and reel the silk, as well as experts who could manage and coordinate the entire process. Difficult as these problems were, if solved, sellers still had to compete in markets with rivals from venerable centers of production in the Old World, ranging from China and India to Italy and France.Through a series of detailed case studies, March chronicles the various sericultural miscarriages in different parts of the Western Hemisphere—New Spain in the sixteenth and early seventeenth centuries, Virginia in the seventeenth century, French Louisiana and the British colonies of South Carolina and Georgia in the eighteenth century, and New England and Pennsylvania in the late eighteenth and early nineteenth centuries. In some instances, the major impediment was the inhospitable environment; in others, it was insufficient or inadequate labor. In certain areas, other economic activities displayed greater economic potential; in others, market competition from more efficient producers proved too formidable. Most often, however, some combination of these factors was decisive. As Marsh also shows, efforts in the early modern period to establish viable sericulture in parts of northern Europe, most notably in England, were hardly immune to such difficulties. Most of the failures detailed by Marsh occurred despite various types of governmental support.At the end of the day, sericulture’s failure to flourish in the Western Hemisphere during the early modern period is not surprising. Given the environmental and labor-market challenges and the opportunity costs associated with silk production, other economic activities undoubtedly offered better profit possibilities. That said, Marsh deserves praise for this fascinating and richly documented study of the trials and tribulations involved in trying to establish sericulture on American soil.
