【摘要】 对一株分离自鱼类致病菌株的个体形态、生理生化特性进行了分类研究 ,确定该菌株为荧光假单胞菌 (Pseudomonasfluorescens) ,其耐热特性以及能利用甘油作为唯一碳源和能量来源 ,与标准模式菌株不同 ,在 4 3℃仍然能够生长 ,研究还表明 ,该菌株产生的荧光色素水溶液在波长 32 5nm的紫外区有最大光吸收值 .更多还原

【Abstract】 A bacterial strain that causes disease of fish was characterized with morphological, physiologic and biochemical analysis. It was proved that this was a Pseudomonas fluorescens species strain. It can utilize glycerol as carbon and energy source. It was thermostable and can grow at 43℃, it different from the model strain. The fluorescent pigment produced by the P. fluorescens cells has maximum value of absorption at wavelength 325nm.更多还原
