Abstract

Chitosan is a biocompatible and biodegradable natural polymer with established antimicrobial properties against specific microorganisms. The present study demonstrates its antibacterial activity against 48 isolates of Vibrio species from prawn larval rearing systems. The antibacterial activity had a positive correlation with the concentration of chitosan. This work opens up avenues for using chitosan as a prophylactic biopolymer for protecting prawn larvae from vibriosis.

摘要

壳聚糖是一种具有生物相容性和可生物降解性的天然聚合物，对特定微生物具有既定的抗菌特性。本研究证明了其对来自对虾幼体养殖系统的48株弧菌分离株的抗菌活性。抗菌活性与壳聚糖浓度呈正相关。这项工作为使用壳聚糖作为预防性生物聚合物来保护对虾幼体免受弧菌病侵害开辟了道路。
