Summary: Thermophilic bacteria isolated from hot springs in Himachal Pradesh produced thermostable xylanases, with B. subtilis VSDB5 and B. licheniformis KBFB4 belonging to the GH11 family and showing potent and alkali-tolerant characteristics. The xylanase enzymes exhibited maximum activity at pH 6 and 50 degrees C, with good retention of activity under various temperature and pH conditions, making them suitable for industrial applications involving high temperatures and alkali treatment.

Summary: Fungal extracellular vesicles (EVs) have potential as therapeutic agents and targets for the treatment of fungal infections. This study found that caffeine, a subinhibitory concentration of methylxanthines, effectively reduces the release of H. capsulatum EVs, leading to a modulation of fungal virulence.

Summary: To ensure food security in the face of climate change and growing population, the usage of plant growth promoting fungi (PGPF) can be an efficient approach. This study focuses on the development of an environmentally responsible seed coating composed of chitin, methylcellulose, and Trichoderma viride spores. The results showed that the seed coating effectively inhibited the growth of pathogenic fungi and did not negatively impact seed germination or induce plant stress response.

Summary: The study found that arbuscular mycorrhizal fungi can improve host plant growth and increase Pb immobilization in the cell wall by increasing the polysaccharide content and inducing cell wall peroxidase activity. Additionally, both the activity of cell wall peroxidase and polysaccharide composition have important contributions to the resistance of mycorrhizal-associated plants.

Summary: With their ability to fix CO2 using sunlight, algae and microalgae are being studied for the production of proteins and valuable compounds. However, the successful utilization of algal biomass relies on effectively disrupting the recalcitrant cell wall. This study evaluated different methods to break up the cell wall and measured success by protein and carbohydrate release. The analysis also identified factors contributing to the robustness of the cell wall.

Summary: A green extraction process is proposed to reduce energy and petroleum solvent consumption, while maintaining environmental safety and quality. The study focuses on generating a highly permeable cell using crude fungal enzymes, enabling simultaneous cultivation and extraction. A novel pretreatment method combining partial enzymatic digestion and maintaining viability of microalgae cells allows for further product recovery from the same biomass.

Summary: In this study, a dominant mutant H51K/Q118A derived from Gloeophyllum trabeum was obtained by directed evolution, which showed higher specific activity, catalytic efficiency, and thermostability compared to the wild type. The mutant also exhibited impressive pH resistance from pH 1.0-9.0. When combined with 'Seawater + Feton' pretreatment, the mutant achieved a lignin clearance rate of 62.5%, 86.6% higher than feton pretreatment. Synergistic hydrolysis with the mutant and cellulase increased the fermentable sugar yields from bagasse by 48.4%.

Summary: Camellia bee pollen protein isolates were extracted using different methods, including ultrasonication, freeze-thawing, enzymatic hydrolysis, and their combinations. The enzymatic hydrolysis method showed the most significant improvement in protein yield, solubility, emulsifying, and gelation properties. The combination of ultrasound with freeze-thawing or enzymatic hydrolysis further enhanced protein yield and functional properties, possibly through changes in protein structure induced by cavitation effect of ultrasound.

Summary: The study found that the application of CuNPs is more beneficial for the biological and biochemical activities of Brassica napus rhizospheric soil compared to the application of AgNPs. The abundance of all tested microbial groups showed a positive correlation with CuNPs but a negative correlation with AgNPs in each application version. Additionally, the impact of different NP concentrations on soil pH value and biochemical parameters varied between CuNPs and AgNPs.
