【摘要】 以大肠杆菌、金黄色葡萄球菌、枯草杆菌为实验菌种,研究了羧甲基壳聚糖的抗菌性能,同时将其配制成一定浓度的溶液,对鲫鱼进行保鲜研究。结果表明:羧甲基壳聚糖对上述3种常见的食品腐败菌都有较强的抑制作用,其中对金黄色葡萄球菌的抑制效果最好,其最小抑制浓度为0.1%,对大肠杆菌、枯草杆菌最小抑制浓度均为0.2%;0.5%羧甲基壳聚糖溶液对鲫鱼有一定的保鲜效果。更多还原

【Abstract】 Antimicrobial activity of carboxymethyl-chitosan were studied by using escherichiacoli, staphylo- coccusaureus and bacillussubtilis as experimental bacteria. The result showed that carboxymethyl-chitosan had stronger bacteriostasis against above-mentioned common bacteria in polluted food. The minimum inhibition concentration(Mic) is 0.1% for staphylococcusaureus, 0.2% for escherichiacoli and bacillussubtilis. The experimental results showed that 0.5% carboxymethyl-chitosan solvent can extend the storage life of carassius auratus.更多还原
