【摘要】 荧光假单胞菌为库存血液常见的污染菌之一.10-36号菌株在4℃、22℃、37℃三种温度下进行培养,观察其生长延迟期和对数生长期的增长速率.结果表明,该菌株在37℃培养时生长缓慢,延迟期和对数期无明显界限,其增代时间为900分钟;22℃时生长延迟期为5小时,对数生长期增代时间为29分钟;4℃时,生长延迟期为30小时,对数期增代时间为300分钟.更多还原

【Abstract】 Pseudomonas fluorescens is one of the most common contaminative bacteria of the stored blood. Ps. fluorescens No. 10-36 was cultured at 4℃, 22℃ and 37℃ for studying its growth phase and logarithmic growth phase. The results showed that this strain grew slowly at 37℃ with a generative rate of 900 minutes, but had no difference between the lag phase and the logarithmic growth phase. At 22℃ the lag phase were 5 hours, and the logarithmic growth phase were 29minutes, while at 4℃, the lag phase was 30 hours and the logarithmic growth phase was 300 minutes.更多还原
