Chitosan was prepared by alkaline N-deacetylation of chitin obtained from shiitake stipes
and crab shells and its antimicrobial and antitumor activities were studied. Chitosan from …

This research aims to study the production of chitosan from shrimp shell (Litopenaeus
vannamei) of waste origin using two chemical methodologies involving demineralization …

In the present study, anticancer activities of chitin, chitosan and low molecular weight chitin
were evaluated using a human tumour cell line, THP-1. A molecular weight–activity …

Chitin was recovered through enzymatic deproteinization of the Norway lobster (Nephrops
norvegicus) processing by-products. The obtained chitin was characterized and converted …

The antimicrobial activities of chito-oligosaccharides against four Gram-positive and seven
Gram-negative bacteria were compared to chitosan and chitin with an emphasis on the …

Chitin is a natural polymeric polysaccharide extracted from marine crustaceans, and
chitosan is obtained by removing part of the acetyl group (usually more than 60%) in chitin's …

Chitin was recovered through enzymatic deproteinization of the shrimp processing by-
products. Different microbial and fish viscera proteases were tested for their deproteinization …

Chitosan obtained from abundant marine resources has been proven to have a variety of
biological activities. However, due to its poor water solubility, chitosan application is limited …

Chitosan with different degree of deacetylation (DD) and ultra high molecular weight (MW>
10 6) was prepared from β-chitin by mild deacetylation. The effects of DD of chitosan and pH …

The effects of the deacetylation degree (DD) and preparation methods for chitosan on
antimicrobial activity were evaluated. Chemically prepared chitin (CH-chitin) and …
