【中文摘要】 分別以幾種細菌、酵母菌和霉菌為指示菌,比較了虎奶菇發(fā)酵液乙酸乙酯提取物與苯甲酸、山梨酸、苯甲酸鈉、山梨酸鉀、乳酸鏈球菌素和鈉他霉素等幾種食品防腐劑的抑菌能力。結果表明,虎奶菇發(fā)酵液的乙酸乙酯提取物對幾種細菌指示菌均有較好抑制作用,尤其對金黃色葡萄球菌(Staphylococcus aureus),枯草芽孢桿菌(Bacillus subtilis),大腸桿菌(Escherichia coli),蠟樣芽孢桿菌(Bacillus cereus)和腸炎沙門氏菌(Sal monellaenteritidis)的抑制效果都顯著高于其它防腐劑;對白色念珠菌(Candida albicans)和啤酒酵母(Saccharomyces cerevisiae)的抑制作用僅次于鈉他霉素;對黃曲霉(Aspergillus flavus)和黑曲霉(Aspergillusniger)的抑制效果較差;對金黃色葡萄球菌、枯草芽孢桿菌、蠟樣芽孢桿菌、大腸桿菌、腸炎沙門氏菌和綠濃桿菌的最小抑菌濃度分別為1.250mg/mL、1.250mg/mL、2.500mg/mL、5.000mg/mL、5.000mg/mL和10.000...更多mg/mL。 還原
【英文摘要】 The anti-microbial activity of ethyl acetate extracts of Pleurotus tuber-regium spent culture liquid was determined and compared with several recognized food preservatives (sorbic acid, benzoic acid, sodium benzoate, potassium sorbate, nisin and natamycin) using several bacteria and fungi as indicators. Ethyl acetate extracts inhibited the growth of Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Bacillus cereus and Salmonella enteritidis more strongly, but exhibited relatively weaker inhibiting capacity towards Aspergillus niger and Aspergillus flavus, compared with the tested food preservatives. Ethyl acetate extracts were less effective than natamycin in inhibiting the growth of Candida albicans and Saccharomyces cerevisiae but more effective compared with the other tested food preservatives. Minimum inhibiting concentrations (MIC) of ethyl acetate extracts for S. aureus, B. subtilis, E. coli, B. cereus, S. enteritidis and P. aeruginosa were 1.25 mg/mL, 1.25 mg/mL, 2.50 ...更多mg/mL, 5.00 mg/mL, 5.00 mg/mL,and 10.00 mg/mL, respectively. 還原
