Detection of hydrolases of different subclasses in cell-free fractions of Vibrio cholerae O1 and O139 serogroups using radial enzymatic diffusion in agarose gel

Microbiology Independent Research Journal, 2023
Cholera remains an actual infection worldwide, which dictates the need for a comprehensive study of its pathogens and, in particular, their hydrolytic enzymes that interact with the cells of the macroorganism.

Necromass chemistry drives the functional diversity of the necrobiome, resulting in microbe–organic matter feedbacks

Functional Ecology, Volume 40, Issue 5, Page 1339-1351, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In temperate European forests, soil fungal communities, dominated by saprotrophic and ectomycorrhizal (ECM) species, represent almost 25% of soil organic carbon (C) in the soil.

Floodplain reforestation reduces nitrate loss through soil microbial pathways

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Reforesting floodplains with native Melaleuca substantially reduced nitrate leaching relative to sugarcane, driven by higher soil organic carbon supporting decomposer‐dominated microbial communities that immobilise nitrogen rather than converting it to leachable nitrate.

STUDIES ON CHITINOLYTIC ENZYME PRESENT IN AQUATIC ANIMALS-II

NIPPON SUISAN GAKKAISHI, 1964
In the previous paper1) in this series, some properties of chitinolytic enzyme present in the stomach of fish, Lateolabrax japonicus, were investigated by measuring the reducing sugar produced. In the present study, chitinase activity was observed by decreasing substrate (Precipitated chitin, P. Ch), because the amount of P.

Thermal Plasticity is Regulated by a Key MicroRNA During Range Expansion of an Invasive Fruit Fly

Advanced Science, Volume 13, Issue 23, 23 April 2026.
Populations at the invasion front of Bactrocera dorsalis adapt through reduced phenotypic and gene expression plasticity, a phenomenon likely to be driven by genetic assimilation. We identify a key miRNA‐mediated regulatory axis, in which miR‐276b post‐transcriptionally represses thw, a conserved chitin‐binding gene critical to the cold‐tolerance ...

Diet‐Driven Divergence in Gut Microbiota Variation Between Two Sympatric Gerbil Species

Ecology and Evolution, Volume 16, Issue 4, April 2026.
ABSTRACT Gut microbiota provide various benefits to their mammalian hosts; however, knowledge regarding interspecific differences in gut microecology remains limited. This study employed 16S rRNA sequencing combined with metagenomic functional prediction (potential functions or functional potential) to conduct a comparative analysis of the gut ...

Computer‐Based Design to Improve Bacillus thuringiensis Chitinase for Industrial Applications

ChemistryOpen, Volume 15, Issue 4, April 2026.
Hotspot‐guided mutagenesis identifies Gly291 as a key catalytic determinant in Bacillus thuringiensis chitinase. Substitution with alanine improves substrate accommodation and lowers the activation barrier by ∼47%, reducing it from 94.66 to 49.83 kcal/mol. Structural integrity is retained while catalytic efficiency is enhanced, demonstrating a rational

A novel thermostable chitinolytic machinery of Streptomyces sp. F-3 consisting of chitinases with different action modes

Biotechnology for Biofuels, 2019
Background The biodegradation of chitin is an important part of the carbon and nitrogen cycles in nature. Speeding up the biotransformation of chitin substrates can not only reduce pollution, but also produce high value-added products.

Affinity of rhizobacterial chitinases towards chitin polymers from shrimp exoskeleton and fungal cell wall: Optimization for effective biocontrol potentials

Carbohydrate Polymer Technologies and Applications
Bacteria that can hydrolyze shrimp shell chitin and fungal cell wall chitin were isolated from tomato rhizosphere soil in an effort to find chitin-degrading enzymes. Extracellular nature of chitinase was confirmed in agarose-chitin.

High Production of Chitinolytic Activity in Halophilic Conditions by a New Marine Strain of Clonostachys rosea

Molecules, 2019
Twenty-eight fungal strains have been isolated from different natural marine substrates and plate screened for their production of chitinolytic activity. The two apparent best producers, Trichoderma lixii IG127 and Clonostachys rosea IG119, were screened
