Promising Prodiginins Biological Activities

Chemistry &Biodiversity, Volume 22, Issue 9, September 2025.
ABSTRACT Prodiginins are a large family of at least 34 pyrrolic compounds, including the well‐studied red pigment prodigiosin. Prodiginins are produced by several microorganisms displaying broad biological activities, including antimicrobial, antiviral, antiparasitic, antiproliferative, and immunosuppressive activities.

N‐acetylglucosamine sensing in the filamentous soil fungus Trichoderma reesei

The FEBS Journal, Volume 292, Issue 12, Page 3072-3090, June 2025.
N‐acetylglucosamine (GlcNAc) is involved in diverse signaling pathways in dimorphic yeasts and bacteria, including virulence and cell death. Here, we investigated GlcNAc sensing in Trichoderma reesei. GlcNAc signaling influences around 2100 genes in this filamentous soil fungus.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Chitosan Oligosaccharide Production Potential of Mitsuaria sp. C4 and Its Whole-Genome Sequencing

Frontiers in Microbiology, 2021
Chitooligosaccharide is a kind of functional food, which is the degradation product of chitosan (COS) catalyzed by the endo-chitosanase (COSE) enzyme. A COSE with a molecular weight of 34 kDa was purified and characterized from a newly isolated Mitsuaria

Gut Microecology of Four Sympatric Desert Rodents Varies by Diet

Ecology and Evolution, Volume 15, Issue 3, March 2025.
We observed significant differences in the gut microbial composition of four species of rodents living in the same habitat but each consuming different diets. These differences in gut microbiota may arise as adaptations to their distinct diets and digestive needs, thereby enhancing their ability to live within the same ecosystem.

Characterization of Chitosanase of a Deep BiosphereBacillusStrain [PDF]

Bioscience, Biotechnology, and Biochemistry, 2011
A chitosanase of deep-biosphere Bacillus thuringiensis strain JAM-GG01 was purified. The optimal pH and temperature for the purified enzyme (Cho-GG) were about pH 6 and 60 °C, but Cho-GG was unexpectedly unstable under incubation at over 40 °C. This discrepancy between higher activity and lower stability in the same range of temperature was abolished ...
