Enhancement of Streptomyces aureoverticillatus HN6 through mutagenesis for improved biocontrol of banana wilt disease: an WGS approach

Fusarium oxysporum-induced Fusarium wilt in bananas is a highly detrimental disease that significantly impedes the progress of the banana industry. In this study, Streptomyces aureoverticillatus HN6 was isolated from soil samples of Hainan Botanical Garden and showed a wide spectrum of bacterial inhibition and a substantial effect on the control of banana wilt disease. While the bacterium demonstrates high inhibitory activity, and the use of live strains is effective, there are limitations in the development and application of this particular strain, such as effective secondary metabolites are difficult to extract; unstable metabolites, and low sporulation rates. Consequently, the strain underwent electron beam mutagenesis, 60Co-γ ray mutagenesis, two cycles of ultraviolet irradiation mutagenesis, and ethyl methanesulfonate (EMS) mutation to generate multiple mutant strains. The mutant strain Z20-1 exhibited resistance to elevated temperatures and enhanced enzymatic activities, specifically increased levels of both amylase and cellulase. Moreover, the fermentation broth of the mutant strain E95 substantially improved the bacterial inhibitory activity. Comparative genomic analysis revealed the presence of seven single-nucleotide polymorphisms (SNPs), one multiple nucleotide polymorphism (MNP), and three insertion-deletions when comparing the mutant strain E95 with the original strain HN6. Notably, the mutant strain E95 exhibited the highest expression of npmC, a core gene in the niphimycin C synthesis gene cluster. Through mutagenesis of the original strain HN6, several mutant strains with superior characteristics were successfully obtained. These findings serve as a valuable technical reference for the mutation breeding of Streptomyces.Graphical

Streamlining life cycle assessment for complex Mechanical Electrical and Plumbing products – Lessons from lighting

Life Cycle Assessment (LCA) is a framework supporting quantification of a product’s environmental impacts. Such data is required for comprehensive assessment of carbon emission impacts over the full life-cycle of products and buildings. With policymakers and the private sector pursuing decarbonisation goals, the need to streamline development of LCA data for Mechanical, Electrical and Plumbing (MEP) items has increased. MEP practitioners are tailoring existing LCA frameworks to accommodate supply chain complexity and unique use-phase scenarios. In lighting, LCA leadership is being driven by designers from consulting/engineering firms and manufacturers committed to identifying data gaps, inconsistencies, and uncertainty in the application of LCA. In 2025, lighting’s first Industry-Average LCA Report will be published as the result of an industry-led, international, collective analysis of five commonly used architectural luminaires. The findings suggest LCA development may be streamlined by articulating the role of manufacturers and designers in accelerating the closure of identified data gaps and adoption of consistent, industry-agreed interpretation of LCA for complex MEP items. Strategies include approaching industry LCA as a design innovation tool rather than compliance issue; assembling designer-manufacturer forums to incentivize commercial cooperation; improving global harmonisation and harnessing Industry-Average Environmental Product Declarations (EPDs) and other tools as an introduction to more specific analysis. Practical Application With increasing significance in the growth of, and requirement for, the adoption of Life Cycle Assessment (LCA) within the built environment, this paper offers leading practitioners and manufacturers an approach that can help identify current data gaps, areas of inconsistency and uncertainty within the discipline of Mechanical Electrical and Plumbing (MEP) LCA. It suggests how engaging multiple stakeholders, particularly manufacturers and designers, can deliver preliminary results that support wider industry progress within this emerging field of data collection and analysis. This paper also provides lighting manufacturers, sustainability specialists and MEP consultants with a more comprehensive understanding of the environmental impact of lighting.

Efficient and accurate tobacco leaf maturity detection: an improved YOLOv10 model with DCNv3 and efficient local attention integration.

The precise determination of tobacco leaf maturity is pivotal for safeguarding the taste and quality of tobacco products, augmenting the financial gains of tobacco growers, and propelling the industry's sustainable progression. This research addresses the inherent subjectivity and variability in conventional maturity evaluation techniques reliant on human expertise by introducing an innovative YOLOv10-based method for tobacco leaf maturity detection. This technique facilitates a rapid and non-invasive assessment of leaf maturity, significantly elevating the accuracy and efficiency of tobacco leaf quality evaluation. In our study, we have advanced the YOLOv10 framework by integrating DCNv3 with C2f to construct an enhanced neck network, designated as C2f-DCNv3. This integration is designed to augment the model's capability for feature integration, particularly concerning the morphological and edge characteristics of tobacco leaves. Furthermore, the incorporation of the Efficient Local Attention (ELA) mechanism at multiple stages of the model has substantially enhanced the efficiency and fidelity of feature extraction. The empirical results underscore the model's pronounced enhancement in performance across all maturity classifications. Notably, the overall precision (P) has been elevated from 0.939 to 0.973, the recall rate (R) has improved from 0.968 to 0.984, the mean average precision at 50% intersection over union (mAP50) has advanced from 0.984 to 0.994, and the mean average precision across the 50% to 95% intersection over union range (mAP50-95) has risen from 0.962 to 0.973. This research presents the tobacco industry with a novel rapid detection instrument for tobacco leaf maturity, endowed with substantial practical utility and broad prospects for application. Future research endeavors will be directed towards further optimization of the model's architecture to bolster its generalizability and to explore its implementation within the realm of actual tobacco cultivation and processing.

Reproduction of Tolerance Habitus in High School Students in the VUCA Era (Volatility, Uncertainty, Complexity, Ambiguity)

The progress of Industry 4.0 has had both positive and negative impacts. One of the impacts that can be felt by today's teenagers is a lack of character development. Character cultivation is carried out not only in the family environment, but can also be done in the school environment. School is an arena for cultivating character values ​​for its students. One of the most highlighted character cultivation in the current era is the cultivation of the character of tolerance between religious communities. Departing from these problems, this research aims to discuss the habitus of tolerance in schools in the VUCA Era (Volatility, Uncertainty, Complexity, Ambiguity), especially for students who are Generation Z. The method used in this research is qualitative by in-depth interviews with school students and conducting Focus Group Discussion (FGD) with student representatives at the Surakarta Ex-Karisidenan. The results of this research show that the UCA Era (Volatility, Uncertainty, Complexity, Ambiguity) has an impact on the process of reproducing the habitus of tolerance in schools. This is because digital processes in the VUCA Era (Volatility, Uncertainty, Complexity, Ambiguity) tend to strengthen polarization and increase disagreement between different groups. When information disseminated via social media or other online platforms tends to mislead or oversimplify the complexity of issues, this can result in stigma, stereotypes, and prejudice against certain groups.

Identification and Characterization of the Y-Organ of Orange Mud Crab Scylla Olivacea.

The Y-organs (YOs) synthesize and secrete molting hormones, and thus regulate crustacean growth and reproduction. However, the YOs of the orange mud crab Scylla olivacea is yet to be described due to its minute size and ambiguous feature. This study describes the location, morphological characteristics, histology, and the changes of YOs at different molt stages, and examines invitro ecdysteroid secreted by the YOs of S. olivacea. Mature male crabs (> 90 mm carapace width, CW) were used to identify the location of the YOs while male juveniles (50-65 mm CW) at three molt stages (intermoult, premoult, postmoult) were dissected for the characterization of 20-Hydroxyecdysone (20E) levels. The yellowish-white, compact, and oval-shaped YOs are located in pairs at the anterior cephalothorax region, beneath the mandibular external adductor muscle, anterior to the branchial chamber space, and around the end of the nerve tract. The YOs index and YO's cell diameter increased from postmoult to premoult; YO's diameter increased only during premoult stage. Under electron microscopy, the YO's surface morphology is rough, bumpy, network-like, and porous, with several lacunar system tubules. High concentrations of haemolymph 20E during premoult correlated with the changes in the characteristics of YOs at this stage. The presence of ecdysteroid in YOs was confirmed by high performance liquid chromatography (HPLC). The characteristics of the YOs of S. olivacea are similar to the YO descriptions of other brachyurans. The successful identification and characterization of YOs will spearhead future research on understanding its role in molt regulation of mud crabs, consequently contributing to the development and progress of crab culture and soft-shell crab industries.

The National Beef Quality Audit (NBQA)-2022 serves as a benchmark of the current market cow and bull sectors of the U.S. beef industry and allows comparison to previous audits as a method of monitoring industry progress. From September 2021 through May 2022, post-slaughter hide-on animals (n = 6,674), carcasses (n = 5,746), and offal items (heads and tongues: n = 7,282; lungs and hearts: n = 6,708; viscera, kidneys, and livers: n = 6,358) were surveyed at 20 commercial beef processing facilities across the United States. There were 37.8% of cattle with no visible mud contamination. Native (unbranded) hides were observed in 88.3% of cattle. Carcass bruising was observed on 66.7% of cow carcasses and 46.4% of bull carcasses, similar to percentages observed in the 2007 and 2016 audits. Nearly all cattle were free of knots (98.2%) or injection-site lesions (97.1%). Harvest-floor assessments found that 45.0% of livers, 22.2% of viscera, 19.3% of kidneys, 46.6% of lungs, 19.9% of hearts, 11.2% of heads, and 6.4% of tongues were condemned. The leading cause of condemnation for these offal items was contamination, aside from livers with the majority resulting in condemnation from the presence of an abscess. Of the cows surveyed, 25.4% carried a fetus, an 8% increase compared to those observed in 2016, and a 14.8% increase compared to cows surveyed in 2007. Findings from the NBQA-2022 identified areas of improvement and areas that required continued research and producer education to improve market cow and bull welfare, by-product quality, and offal value.

Does national intellectual capital matter for productivity? International evidence

PurposeIn the context of the contemporary globalized environment and the rapid progression of Industry 4.0, the existing literature suggests that national intellectual capital does play a significant role in shaping diverse economic metrics. However, the connection between national intellectual capital and total factor productivity (TFP) has been largely overlooked. This paper examines the effect of national intellectual capital on productivity across 84 countries, encompassing diverse income levels, human development index (HDI) levels and continents.Design/methodology/approachThis study utilizes dynamic ordinary least squares (DOLS), fully modified ordinary least squares (FMOLS), two-stage least squares (2SLS), generalized method of moments (GMM) and pooled mean group (PMG) estimation techniques on a sample of 84 economies from 2000 to 2019.FindingsThe results reveal a significant effect of national intellectual capital on productivity. Countries with robust intellectual capital exhibit enhanced productivity and, by extension, sustainable economic growth. The findings are nuanced, illustrating varied impacts across low, middle and high-income countries and offering insights into tailored strategies for each income group. Nations with lower HDI levels derive significant benefits from investments in intellectual capital, whereas higher HDI countries experience lower returns in productivity gains from additional intellectual capital investments. Interestingly, Latin America exhibits a paradoxical negative effect of national intellectual capital on TFP.Practical implicationsThis paper makes a significant contribution to the literature by extending the discourse on intellectual capital to the national level, an area that has been relatively underexplored. The comparative analysis across income groups, human development index levels and continents enriches the understanding of the multifaceted impacts of intellectual capital on productivity. These insights are valuable for policymakers, researchers and international development agencies, providing a comprehensive perspective on how intellectual capital influences productivity in diverse economic and developmental contexts.Originality/valueTo the best of our knowledge, this is the first empirical study to investigate the impact of national intellectual capital on productivity across 84 countries, considering diverse income levels, HDI levels and continents.

Analisis Kinerja Keuangan Bank Syariah Indonesia Sebelum dan Sesudah Merger Menggunakan Metode Maqashid Shariah Index dan Profitabilitas

Bank Syariah Indonesia was established on February 1,2021. The establishment of Bank Syariah Indonesia was a combination of 3 (three) BUMN Banks (State Owned Enterprises), namely Bank Syariah Mandiri, BNI Syariah, and BRI Syariah. For this reason, the merger of the three banks aims to realize efforts to build an advanced Islamic bank. On the other hand, the progress of an Islamic banking industry is certainly inseparable from the evaluation of the Islamic bank's financial performance. This aims to determine the financial conditions that occurred during a certain period, in which this information is intended for the government, investors and customers of the Islamic bank. So because of this, the authors are interested in measuring the performance of Indonesian Sharia Banks, which can still be said to be new because it is the result of the merger of the three state-owned banks based on the Maqashid Sharia Index and Profitability concept. This research aims to analyze the performance achievements of Bank Syariah Indonesia before and after the merger using the Maqashid Shariah Index and Profitabilta methods and to compare the two performance achievements. The results of the study found that after the Merger, Indonesian Sharia Banks achieved the highest average MSI Performance ratio (Maqashid Syariah Index) and Profitability Performance ratios compared to before the Merger.

Improving Iron Content in Sustainable Mycoprotein Production through Seawater Fermentation

The growing global population and rising protein demand are straining freshwater resources. Fusarium venenatum (Fv) mycoprotein offers a sustainable protein alternative, with environmental efficiency and potential health benefits. However, its low iron content remains a concern, especially for vegetarians and vegans. This study introduces a sustainable approach, employing seawater as a fermentation medium for Fv production. Our analysis reveals that mycoprotein derived from SEA Fv exhibits elevated levels of sodium and calcium, with a notably high iron content (2.2 mg/100g wet weight). The sodium content, while 3.31 times higher than in non-seawater fermentation, remains within recommended daily intake parameters. No plasticizers or heavy metals were detected in the SEA Fv cell body, minimizing long-term toxicity risks from seawater use. A unique metabolite, dihydroorotic acid, was identified from an in-house library of 774 metabolites, serving as an internal biomarker for seawater-based production methods. An acute safety study condensing 600g of SEA Fv to simulate high mycoprotein digestion showed no effects on key physical behaviors or major organs, including the heart and lungs. This positions the product as a viable protein alternative with enhanced iron content, highlighting seawater-based fermentation as a sustainable method for future food production and industry progress.

Implementation of machine learning tool for continued process verification of process chromatography unit operation.

Recent advancements in technology, such as the emergence of artificial intelligence (AI) and machine learning (ML), have facilitated the progression of the biopharmaceutical industry toward the implementation of Industry 4.0. As per the guidelines set by the USFDA, process validation for biopharmaceutical production consists of three stages: process design, process qualification, and continuous process verification (CPV). This paper proposes a strategy for achieving CPV for a cation exchange chromatography unit operation, emphasizing the urgent need for such strategies in the biopharmaceutical industry. Statistical process control (SPC) charts were generated based on real-time measurement of the various critical process parameters (CPPs) measured via in-built sensors (pH, conductivity, UV, and delta column pressure) as well as of critical quality attributes (CQAs) like charge variant composition (Raman spectroscopy) and concentration (Near infrared spectroscopy). A Python-based program was created to read these SPC charts and respond to any deviation. The developed models for NIR coupled DNN PAT tool and Raman coupled DNN PAT tool exhibited satisfactory R2 values (> 0.90), highlighting the statistical significance of the proposed model. Further, the control strategy designed based on Raman spectroscopy for charge variant composition in CEX eluate has been demonstrated by intentional perturbations in the CEX load. The resulting CEX eluate output showed a consistent charge variant composition as that of control runs (acidic ∼20 ± 2 %, main ∼62 ± 2 % and basic ∼18 ± 2 %). It has been demonstrated how an appropriate selection of analyzers, soft sensors, and advanced data analytics can be used to execute CPV and enable the biopharmaceutical industry to implement Industry 4.0.
