In-depth recognition of mixed surfactants maintaining the enzymatic activity of cellulases through stabilization of their spatial structures

Mixed surfactants improve the enzymatic hydrolysis of lignocellulosic substrates by enhancing cellulase stability against heat, pH, shear, and air–liquid interface stress. Under conditions of multiple factorial stresses (50 °C, pH 4.8, 180 rpm, and 15.5 cm2 air–liquid interface), cellulase with ternary surfactants (Tween 60/Triton X-114/CTAB, the molar ratio 14:5.5:1) retained 84 % of its activity after 48 h of incubation, representing 1.15 and 1.29 folds that of the cellulase activity with the single Tween 60 and with no surfactants, respectively. This is attributed to the fact that ternary surfactants possess better rheology modulation and air–liquid interface competitiveness. In addition, the computational approach demonstrated that the ternary surfactants were capable of forming stronger hydrophobic and hydrogen-bond interactions with cellulase enzymes, thus maintaining its secondary structure and preventing the detrimental α-helix to β-sheet transformation known to compromise cellulase activity. This synergy offers valuable insights into surfactant-cellulase interactions and supports efficient enzymatic hydrolysis in biorefineries.

Hypoglycemic activity of enzymatically extracted Eucommia ulmoides polysaccharide (EUL-w1) on IR-HepG2 cell via the AMPK/PI3K/Akt signaling pathway

This study devised optimal conditions to extract Eucommia ulmoides leaf (EUL) polysaccharides using a cellulase and pectinase composite enzyme system based on one-way experiments and response surface methodology. Crude EUL polysaccharides (EULPs) were extracted and purified using a DEAE chromatography column. The polysaccharides EUL-w, EUL1, EUL2, and EUL3 were obtained by elution with water, 0.1 mol/L NaCl, 0.2 mol/L NaCl, and 0.3 mol/L NaCl, respectively. The EUL-w fraction had the highest hypoglycemic activity based on its α-amylase and α-glucosidase activities. The preliminary structure of purified EUL-w1 was elucidated. In vitro hypoglycemic activity studies and metabolomics analyses suggested that EUL-w1 modulated glucose metabolism by mediating the AMPK/PI3K/Akt signaling pathway. Our findings provide novel insights and data support for the utilization of EULPs as an emerging food resource in functional foods.

Endophytic fungi from <i>Dichrocephala integrifolia</i>: Diversity, antifungal properties, enzymatic activities, and plant growth promotion

Dichrocephala integrifolia is a wild medicinal plant utilised in traditional healing and Ayurveda to cope up with several health issues by various groups of people around the world. Medicinal plants are associated with diverse fungal endophytes with potential bioactive properties. In this investigation, 26 fungal endophytes were isolated from D. integrifolia and three sterile forms using the Petri plate culture method. The endophytic isolation rate was highest for inflorescence (35.97%) and lowest for stem (15.61%). The highest colonization frequency was shown by F. solani (8.37%) and the lowest by Sterile morphotype 3 (1.36%). Out of the four plant parts, inflorescence was found to be highly infected, displaying an infection rate of 93.43% and the least infection occurred in the stem with 45%. The maximum number of isolated endophytic fungi belongs to the class Sordariomycetes, with a relative occurrence (%) of 71.72%. The Simpson’s diversity index reveals that the leaf endophytes were more diverse (0.94). Qualitative antifungal activity of the sporulating isolates against Curvularia lunata has shown that the maximum number of endophytes possessed Class 3 antagonism. Four isolates were selected based on screening of their antagonistic activity and their antifungal inhibition was calculated against nine fungal phytopathogens. Maximum inhibition (100%) was shown by Trichoderma sp. 2 (S2B2) against Alternaria alternata, A. brassicicola, Colletotrichum capsici, C. lunata, and Ustilaginoidea virens and least inhibition by Gliocladium sp. 1 (19.78%) against C. lunata. The four isolates were found to produce protease, lipase, amylase and cellulase enzymes. The isolates produced ammonia and hydrogen cyanide, but none of the isolates could solubilize phosphate. Potent biocontrol agents are much needed to replace synthetic chemicals and restore soil microflora.

Optimization of Cellulase Production from Agri-Industrial Residues by Aspergillus terreus NIH2624

The objective of this study was to assess the cellulase production of four fungi: Aspergillus terreus NIH2624, Aspergillus clavatus NRRL1, Aspergillus versicolor CBS583.65 and Aspergillus phoenicis ATCC3157, under submerged cultivation conditions. When these fungi were cultured in shake flasks using Mandels and Weber’s minimal medium with 1% sugarcane bagasse as a carbon source and 1.8 g/L of rice bran extract as a nitrogen source, A. terreus showed maximum cellulase production (filter paper activity (FPase) 3.35 U/mL; carboxymethyl cellulase activity (CMCase) 1.69 U/mL). Consequently, A. terreus was selected for the optimization study for cellulase production. Among the different tested carbon sources, A. terreus showed higher CMCase activity when it was cultivated on delignified sugarcane bagasse (1.64 U/mL) and higher FPase activity on sugarcane straw (7.95 U/mL). Regarding the nitrogen sources, the maximum FPase activity was observed when using rice bran (FPase, 8.90 U/mL) and soybean meal (FPase, 9.63 U/mL). The optimized fermentation medium (minimal medium with delignified sugarcane bagasse and rice bran as carbon and nitrogen sources, respectively) resulted in an enzymatic cocktail mainly composed of xylanases, with a maximum activity of 1701.85 U/mL for beechwood xylan, 77.12 U/mL for endoglucanase and 21.02 U/mL for cellobiohydrolase. Additionally, the enzymatic cocktail showed efficient activities for β-glucosidase, β-xylanase, arabinofuranosidase and lytic polysaccharide monoxygenases (LPMOs). This cellulase enzyme solution has the potential to efficiently hydrolyze lignocellulosic biomass, producing second-generation sugars in biorefineries.

Enzymatic modification of cotton fibre polysaccharides as an enabler of sustainable laundry detergents

Cotton is the most common natural fibre used in textile manufacture, used alone or with other fibres to create a wide range of fashion clothing and household textiles. Most of these textiles are cleaned using detergents and domestic or commercial washing machines using processes that require many chemicals and large quantities of water and energy. Enzymes can reduce this environmental footprint by enabling effective detergency at reduced temperatures, mostly by directly attacking substrates present in the soils. In the present study, we report the contribution of a cleaning cellulase enzyme based on the family 44 glycoside hydrolase (GH) endo-beta-1,4-glucanase from Paenibacillus polymyxa. The action of this enzyme on textile fibres improves laundry detergent performance in several vectors including soil anti-redeposition, dye transfer inhibition and stain removal. Molecular probes are used to study how this enzyme is targeting both amorphous cellulose and xyloglucan on textile fibres and the relationship between textile surface effects and observed performance benefits.

Cordyceps militaris solid medium polysaccharides (CMMPs) were extracted using an ultrasound-assisted enzyme method, and the process conditions were optimized via response surface methodology (RSM). The CMMPs were separated into four components named CMMP-1, CMMP-2, CMMP-3 and CMMP-4 using ethanol fractional precipitation, and their monosaccharide composition and structural properties were analyzed by molecular weight analysis, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Congo red test, ultraviolet-visible spectroscopy (UV-vis), atomic force microscopy (AFM), and thermogravimetric analysis (TGA). RSM could predict the yield of the CMMP (R2 = 0.9928), and the polysaccharide yield was 15.43% under the selected conditions of 3.1% cellulase enzyme addition, a liquid-solid ratio of 42:1, an extraction temperature of 61 °C, and an extraction time of 60 min. Glucose and galactose were the main constituents of the four fractional precipitated polysaccharides. Furthermore, four components exhibited antioxidant activity, and CMMP-1 demonstrated stronger antioxidant activity in vitro. This study demonstrates the possibility of developing a natural antioxidant food from Cordyceps militaris solid medium.

Cellulase exhibited a therapeutic potential to inhibit Salmonella enterica serovar Typhi biofilm by targeting multiple regulatory proteins of biofilm

Biofilm-mediated Salmonella enterica serovar Typhi (Salmonella Ser. Typhi) infections are a growing global health issue due to the formation of antibiotic resistance. The study aimed to discover some of the druggable target proteins of Salmonella Ser. Typhi biofilm and antibiofilm enzyme to prevent Salmonella Ser. Typhi biofilm-mediated infection. Enzymatic therapy has demonstrated effective therapeutic results against bacterial infections due to its specificity and high binding capacity to the target. Therefore, this study focused on the computational interaction between the cellulase enzyme and Salmonella Ser. Typhi biofilm targets proteins with help of the various computational experiments such as ADMET (absorption, distribution, metabolism, excretion, and toxicity), protein-protein interactions, MMGBSA, etc. Further, in vitro validations of the typhoidal biofilm and cellulose presence in Salmonella Ser. Typhi biofilm was conducted using Scanning Electron Microscopy (SEM), Fourier transform infrared spectroscopy, and Raman analysis. Additionally, a minimum biofilm inhibitory concentration assay for cellulase was conducted and find out the optimized cellulase concentration which showed its inhibitory effect on the Salmonella Ser. Typhi. The cellulase antibiofilm effect was analyzed with the help of SEM analysis. Further, the cellulose content in Salmonella Ser. Typhi was quantified before and after treatment of cellulase enzyme. As a result, 58.82 % cellulose content was decreased due to cellulase treatment in Salmonella Ser. Typhi. From the seven selected typhoidal biofilm regulatory proteins of Salmonella Ser. Typhi, we identified only five potential druggable targets: BcsA, CsgE, OmpR, CsgF, and CsgD. The BcsA protein is responsible for cellulose production in Salmonella Ser. Typhi biofilm. Consequently, cellulose worked as a fascinating drug target in Salmonella Ser. Typhi biofilm. Therefore, we used cellulase as a potential antibiofilm enzyme for target-based disruption of biofilm. The cellulase showed a high binding affinity with all five identified target proteins [BcsA(-205.62 kcal/mol) > CsgE(-108.20 kcal/mol) > OmpR(-107.58 kcal/mol) > CsgF(-73.74 kcal/mol) > CsgD(-66.61 kcal/mol)] in the protein-protein interaction analysis. Our computational analysis suggests that the cellulase enzyme may be used as a potential antibiofilm enzyme against Salmonella Ser. Typhi biofilm.

Bioethanol production from groundnut shell using microorganisms derived from sugarcane root soil

Bioethanol is a form of renewable energy that can be produced from fuel or energy crops. Ethanol is produced by the fermentation of sugars present in agricultural feed stocks and crop residues. This study investigates the use of agro wastes like groundnut shells for ethanol production. Initially, the groundnut shells were washed, dried and grinded into powder. Then it was subjected to ethanol production using yeast. After 20 days of incubation the ethanol was estimated using potassium dichromate method. The maximum ethanol yield (1.55%) was obtained when 1% yeast was used. To increase the efficiency of ethanol production, the cellulolytic bacteria was isolated from the cow dung dumped soil site. The 10 bacterial isolates were screened for cellulase enzyme production. Among them one bacterium showed maximum decolourization of congored which was subjected for enzyme production in nutrient broth. The organism showed maximum enzyme activity of 558.12 U/ml. The isolated cellulolytic bacteria were identified as Bacillus anthracis using 16s rDNA sequencing. Ethanol production from the groundnut shells was again carried out with various concentration of crude cellulase enzyme isolated from the bacteria. The estimation result showed 3.8% of ethanol as maximum. Then the ethanol was condensed using a rotary evaporator and when again estimated, showed 7.3% of ethanol. Finally, the presence of ethanol was confirmed by iodoform test. Thus, groundnut shells can efficiently be used for the production of ethanol, which can be used as a high potential fuel source for transportation in the future.

Green manure (Ophiopogon japonicus) cover promotes tea plant growth by regulating soil carbon cycling.

In mountainous tea plantations, which are the primary mode of tea cultivation in China, issues such as soil erosion and declining soil fertility are particularly severe. Although green manure cover is an effective agricultural measure for restoring soil fertility, its application in mountainous tea plantations has been relatively understudied. This study investigated the effects of continuous green manure cover using the slope-protecting plant Ophiopogon japonicus on tea plant growth and soil microbial community structure. We implemented three treatments: 1 year of green manure coverage, 2 years of coverage, and a control, to study their effects on tea plant growth, soil physicochemical properties, and soil bacterial and fungal communities. Results demonstrate that green manure coverage significantly promote the growth of tea plants, enhanced organic matter and pH levels in soil, and various enzyme activities, including peroxidases and cellulases. Further functional prediction results indicate that green manure coverage markedly promoted several carbon cycling functions in soil microbes, including xylanolysis, cellulolysis, degradation of aromatic compounds, and saprotrophic processes. LEfSe analysis indicated that under green manure cover, the soil tends to enrich more beneficial microbial communities with degradation functions, such as Sphingomonas, Sinomonas, and Haliangium (bacteria), and Penicillium, Apiotrichum, and Talaromyce (fungi). In addition. Random forest and structural equation models indicated that carbon cycling, as a significant differentiating factor, has a significant promoting effect on tea plant growth. In the management practices of mountainous tea plantations, further utilizing slope-protecting plants as green manure can significantly influence the soil microbial community structure and function, enriching microbes involved in the degradation of organic matter and aromatic compounds, thereby positively impacting tea tree growth and soil nutrient levels.

Cellulase Enzyme Production Using Actinobacillus sp. on Several Alternative Growth Media

Cellulase enzymes are widely used in the food, beverage, animal feed, textile, and paper industries. The high cost of producing enzymes and low enzyme activity provides opportunities for using chemicals, and efforts are needed to produce cellulase enzymes economically through media optimization. This research aims to find alternative media that make it possible to produce cellulase enzymes with high activity. This research created a control media (M0) using pro-analysis chemicals and CMC as a carbon source. Three types of cellulolytic bacterial growth media were also created, consisting of technical chemicals, rice straw as a substrate, and different protein sources. M1: alternative media using urea as a protein source; M2: alternative media using powdered milk as a protein source; and M3: alternative media using chicken liver as a protein source. A total of 1% of cellulolytic bacteria (Actinobacillus sp.) was grown in each media and then incubated at 40°C for 33 hours at a speed of 140 rpm, and the production curve and cellulase enzyme activity were measured at every 3-hour interval. The results showed that the highest cellulase enzyme production was achieved at 24 hours using alternative media with powdered milk (M2) as a protein source. The cellulase enzyme activity produced was 2.9612 µ/ml.

Controllable preparation and morphology regulation of nanocelluloses from waste paper by a green hydrolysis method

This study focused on the morphology regulation of nanocelluloses (NCs) aiming at preparing NCs with the controllable properties. NCs with rod-shaped, spherical, and rod-shaped and spherical composite structures were prepared from waste paper by a green enzymatic hydrolysis. The critical enzyme concentration for the transition of NCs from one morphology to another was explored. Several analytical methods, including TGA, XRD, SEM, TEM, DSC and WCA, were employed to characterize the prepared NCs. The results showed that with the cellulase enzyme concentration lower than 6 μ/ml or higher than 30 μ/ml, the prepared NCs had a single rod-shaped or spherical structure. When the cellulase concentration was between 6 and 30 μ/ml, the prepared NCs had a composite morphology of rods and spheres. Besides, NCs with a composite morphology dominated by rod-like or spherical structures had a higher thermal stability. Moreover, NCs prepared with cellulase enzyme concentration of 6 and 35 μ/ml had the highest and lowest crystallinity of 81.7 % and 59.3 %, respectively. Hence, this work achieved the morphology and property regulation of NCs by a green method which expanded the application scope of NCs and realized the high value utilization of waste paper.

Characterization and Pathogenicity of Colletotrichum truncatum Causing Hylocereus undatus Anthracnose through the Changes of Cell Wall-Degrading Enzymes and Components in Fruits.

Anthracnose is one of the destructive diseases of pitaya that seriously affects the plant growth and fruit quality and causes significant yield and economic losses worldwide. However, information regarding the species of pathogens that cause anthracnose in pitaya (Hylocereus undatus) fruits in Gansu Province, China, and its pathogenic mechanism is unknown. Thus, the purposes of our present study were to identify the species of pathogens causing H. undatus fruits anthracnose based on the morphological and molecular characteristics and determine its pathogenic mechanism by physiological and biochemical methods. In our present study, forty-six isolates were isolated from the collected samples of diseased H. undatus fruits and classified as three types (named as H-1, H-2, and H-3), according to the colony and conidium morphological characteristics. The isolation frequencies of H-1, H-2, and H-3 types were 63.04%, 21.74%, and 15.22%, respectively. The representative single-spore isolate of HLGTJ-1 in H-1 type has significant pathogenicity, and finally we identified Colletotrichum truncatum as the pathogen based on the morphological characteristics as well as multi-locus sequence analysis. Moreover, the H. undatus fruits inoculated with C. truncatum had a significantly increased activity of cell wall-degrading enzymes (CWDEs) cellulase (Cx), β-glucosidase (β-Glu), polygalacturonase (PG), and pectin methylgalacturonase (PMG), while having a decreased level of cell wall components of original pectin and cellulose in comparison to control. The average increased activities of Cx, β-Glu, PG, and PMG were 30.73%, 40.40%, 51.55%, and 32.23% from day 0 to 6 after inoculation, respectively. In contrast, the average decreased contents of original pectin and cellulose were 1.82% and 16.47%, respectively, whereas the average increased soluble pectin content was 38.31% in comparison to control. Our results indicate that C. truncatum infection increased the activities of CWDEs in H. undatus fruits to disassemble their cell wall components, finally leading to the fruits' decay and deterioration. Thus, our findings will provide significant evidence in the controlling of pitaya anthracnose in the future.

Aminated lignin improved enzymatic hydrolysis of cellulosic substrate treated by p-toluenesulfonic acid

Lignin can affect the enzymatic hydrolysis efficiency of lignocellulose. In this study, the lignin isolated from sugarcane bagasse (SCB) pretreated with p-toluenesulfonic acid (PL) was firstly aminated, and then the effects of PL and aminated PL (APL) on the bagasse enzymatic hydrolysis efficiency (EHE) were investigated. The results showed that the addition of PL and APL promoted the EHE, and EHE with APL (73.82 %) was higher than PL (51.39 %). To explore the reason, the data were further analyzed including cellulase adsorption capacity, enzyme activity, cellulase-lignin interaction, and molecular docking. It was found that APL adsorbed more cellulase (27.83 mg protein/g lignin) than PL (4.96 mg protein/g lignin), resulting from the greater interaction force and lower binding free energy between APL and cellulase. The addition of APL more remarkably enhanced the cellobiohydrolase and endoglucanase activities than PL due to more effectively inducing cellulase conformation optimization.

A Study on The Capabilities of Cellulolytic Bacteria in Degrading Feed Fiber

The utilization of local feedstuffs is a cost-effective strategy to reduce production expenses in animal husbandry. Enhancing the nutritional quality of these feedstuffs through fermentation presents a viable approach. This study investigates the efficacy of cellulolytic bacteria in degrading fiber in three local feed materials: duckweed (Lemna minor), water hyacinth (Eichornia crassipes), and lamtoro (Leucaena leucocephala). We employed a completely randomized block design with feed types as the block and levels of starter culture as treatment. Pediococcus pentosaceus, identified for its cellulase enzyme production with a clear zone of 4 cm on starch media, was utilized as the starter culture. The experimental procedure involved spraying Pediococcus pentosaceus onto duckweed, water hyacinth, and lamtoro, followed by incubation. The results indicated that Pediococcus pentosaceus effectively produced cellulolytic enzymes and significantly reduced crude fiber in duckweed by 18.18%, in water hyacinth by 9.17%, and in lamtoro by 4.23% (p < 0.05). Additionally, the crude protein content increased in all samples: by 4.69% in duckweed, 2.71% in water hyacinth, and 2.13% in lamtoro (p < 0.05). Among the treatments, the optimal outcome was achieved with 3 ml of Pediococcus pentosaceus. This study demonstrates the potential of Pediococcus pentosaceus for improving the nutritional profile of local feedstuffs through fermentation.
