Extraction, characterization and bioactivity of chitosan from farms shrimps of Basra province by chemical method (original) (raw)

2020

Abstract

This paper include the extraction of chitin and transformation it to chitosan from the shrimps shells (waste) that grow up at sea farm in Al-Basra Province, the extraction done according to the literatures by two methods the difference between them was in the first step, but other steps were same methods, the results show sample A was higher than sample B in good yield and other physicochemical properties ( moisture, intrinsic viscosity, daacetylation degree, solubility, and fat binding capacity) which were measured to both samples, chitosan samples were characterization with FT-IR spectrum, in addition the biological activity for chitosan was tested against E.coli, P. asparagi, S. aureus, and B. cerus, the results show that sample A has inhibited these bacteria more than sample B.
