【摘要】 选用嗜水气单胞菌、副溶血弧菌、荧光假单胞菌3种常见水产病原菌,用于测定柠檬酸的抑菌效果及最小抑菌浓度,并研究了柠檬酸抑菌作用的持续性。其中荧光假单胞菌为革兰氏阴性菌。试验结果表明,柠檬酸对3种菌都有不同程度的抑菌作用,并得到最小抑菌浓度,依次是:0.0011g/ml,0.0008g/ml,0.00125g/ml;在最小浓度下抑菌作用可达6d之久,可见柠檬酸抑菌效果有较好的持续性。更多还原

【Abstract】 Effect of inhibiting bacteria and Minimum Inhibitory Concentrations (MICs) were determined for citric acid for aeromonas hydrophila, vibrio parahaemolyticus and pseudomonas fluorescens, which of three bacteria being species of aquatic pathogenic bacteria, including durative of inhibiting bacteria. Pseudomonas fluorescens is G-. The results indicate that citric acid for three bacteria are inhibitable. MICs for aeromonas hydrophila, vibrio parahaemolyticus and pseudomonas fluorescens respectively are 0.001 1g/ml,0.000 8g/ml,0.001 25g/ml. Durative may be five days, and the effect is quit permanence.更多还原
