纳他霉素抑菌效果及其应用研究

Studies on the application and effect of restraining bacteria of natamycin

论文主要研究纳他霉素的抑菌效果及其应用。试验结果表明:霉菌总数为500个/mL时,纳他霉素对黑根霉的最低抑菌浓度是400 mg/L,对黑曲霉的最低抑菌浓度是800 mg/L;霉菌总数为50个/mL时,纳他霉素对黑根霉的最低押菌浓度是200 mg/L,对黑曲霉的最低抑菌浓度是600 mg/L;纳他霉素在pH为6时、25℃时抑菌效果较好,紫外线、重金属能使纳他霉素失去抑菌活性;纳他霉素在酱油中应用效果良好。

This thesis mainly is studied on Effect of restraining bacteria and application of Natamycin. The research results were showed as following. The MIC value was 400 mg/L for Rhizopus nigricans, 800mg/L for aspergillus niger as mould totality is 500 entries/ml; The MIC value was 200 mg/L for Rhizopus nigricans, 600mg/L for aspergillus niger as mould totality is 50 entries/mL; The Natamycin is found to have more antimicrobial activity under pH = 6 and 25℃; Ultraviolet radiation and Heavy metal result in reducing activity of restraining bacteria.
