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

An Economical Bioprocess for Lipopeptide Production From Bacillus subtilis

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
The lipopeptide (LP) production potential of Bacillus isolates was evaluated against phytopathogenic fungi, with B. subtilis 4‐Ka‐22 identified as the top‐performing strain. Optimization of the production medium—comprising molasses, soybean meal, CaCl2, and glycerol—resulted in a 13.4‐fold increase in cell growth and over 99% cost reduction compared to

Virtual Screening of Inhibitors for Chitosanases EAG1

Advances in Enzyme Research, 2020
Chitosanases EAG1 is a classical glycoside hydrolase from Bacillus ehimensis. The previous researches showed that this Chitosanases can not only hydrolyze the b1,4-glycosidic bonds of chitosan to COS in different sizes but also keep a high catalytic activity in organic, which was useful for producing chitooligosaccharides and GlcN for use in the food ...

Cell‐in‐Shell Metacells in Single‐Cell Nanoencapsulation

ChemPlusChem, Volume 91, Issue 4, April 2026.
Metacells represent the next generation of living cell‐in‐shell architectures, chemically engineered through single‐cell nanoencapsulation and characterized by three functional hallmarks: reconfigurability, loadability, and motility. Single‐cell nanoencapsulation (SCNE) enables the direct integration of synthetic materials with living cells, forming ...

Production, purification, and characterization of an extracellular chitosanase from Streptomyces [PDF]

Journal of Bacteriology, 1975
The synthesis by Streptomyces sp. no. 6 of an extracellular chitosanase was induced by glucosamine. The enzyme was purified to homogeneity by Sephadex G-100, carboxymethyl-cellulose, and diethylaminoethyl-cellulose chromatography. The purified enzyme hydrolyzed chitosan (the beta-1,4-linked polymer of glucosamine) but not chitin nor carboxymethyl ...
