Chitooligosaccharides enzymatic production by Metarhizium anisopliae

Bioprocess and Biosystems Engineering, 2010
The products of chitosan hydrolysis are chitooligosaccharides and are used mainly for medical applications due to their specific biological activities. The objective of this study was to detect and identify the products of enzymatic hydrolysis of chitosan (dimers to hexamers) using a crude extract of chitosanolytic enzymes produced by the fungus ...

Developing Active Bilayer Films Based on Poly(Lactic Acid) and Gelatin or Sodium Caseinate

Polymers for Advanced Technologies, Volume 37, Issue 4, April 2026.
ABSTRACT Bilayer films made from polymers with complementary properties, such as poly(lactic acid) (PLA) and proteins, loaded with active agents allow to produce materials with additional functionality compared to those used in conventional packaging. The objective of this research was the development of bilayer films based on PLA acting as the passive

Entomopathogenic Potential of Cuticle‐Degrading Enzymes From Bacillus velezensis CE100 in the Biocontrol of Pine Aphid (Eulachnus thunbergii Wilson)

Entomological Research, Volume 56, Issue 4, April 2026.
ABSTRACT Pine aphids are notoriously destructive sap‐sucking pests of pine trees worldwide. We investigated the biocontrol efficacy of Bacillus velezensis CE100 through cuticle‐degrading enzymes, which degrade the cuticular structure of insect pests.

Chitooligosaccharides antagonize the cytotoxic effect of glucosamine

World Journal of Microbiology and Biotechnology, 2011
Chitooligosaccharides (COS) are partially hydrolyzed compounds derived from chitosan that exhibit a number of biological activities, including antitumor, antibacterial and antifungal properties. In this work, we examined the cytotoxicity of pure COS and oligomers A, B and C (solutions composed of different amounts of COS) produced by enzymatic ...

Enzyme-Linked Immunosorbent Assay for Detection of Chitooligosaccharides

Bioscience, Biotechnology, and Biochemistry, 2000
In order to detect chitooligosaccharides (COS), an enzyme-linked immunosorbent assay (ELISA) was developed. A chitooligosaccharide mixture (COSM) conjugated to bovine serum albumin was used to immunize rabbits to produce an anti-COS polyclonal antibody.
