Chitin oligomers
WebFeb 3, 2024 · In Verticillium and Fusarium species, virulence is reduced when genes encoding specific secreted chitin deacetylases are deleted, and it is hypothesized that these enzymes deacetylate chitin oligomers in the apoplast, which reduces their ability to trigger defense responses (Gao et al. Citation 2024). In several fungal plant pathogens, α-1,3 ... WebChitin oligomers have numerous industrial applications. However, chitin’s crystalline nature requires pretreatment before breakdown into oligomers. In the study, a novel marine bacterium Bacillus aryabhattai is isolated from the Arabian Sea. Bacterial growth in different crystalline chitin substrates like chitin powder, chitin flakes, and ...
