Abstract

The microcolony formation at 30℃ on an enriched minimal salts agar plates by individual Escherichia coli cells heated at 50℃ was monitored with a time-lapse shadow image analysis system, MicroBio μ3DTM AutoScanner. While the time course of microcolony count detected every half an hour for the unheated cells seemingly demonstrated a normal distribution, that for the heated cell population demonstrated totally the growth delay probably resulting from cell injury and also interestingly distributed in its rather deformed pattern with a tailing. Those patterns of the cumulative counts of appearing microcolonies during the post-heating cultivation period were expressed in three different mathematical models. This approach may be proposed as a rapid cultivation method predictable for enumeration of viable and repairable injured cells in practical use.

大肠杆菌单个热损伤细胞形成微菌落的检测时间分布。
用延时阴影图像分析系统MicroBio μ3DTM AutoScanner监测大肠杆菌细胞在50℃下加热30℃时在富盐琼脂板上形成微菌落的情况。未加热的细胞每半小时检测到的微菌落计数的时间过程似乎呈正态分布,而加热后的细胞群则完全表现出生长延迟,可能是由于细胞损伤造成的,而且有趣的是,微菌落计数呈相当变形的尾状分布。用三种不同的数学模型表达了加热后培养期间出现的微菌落累积计数的模式。该方法可作为一种可预测的快速培养方法,在实际应用中枚举有活力和可修复的损伤细胞。
