Abstract

A new apparatus was developed for measuring changes in E(h), pH, and cell numbers. With this apparatus, the relationships of these parameters were studied at initial E(h) levels of 200 and 40 mv (pH 7.0), by using Clostridium perfringens and Pseudomonas fluorescens. One of the strains of C. perfringens grew more luxuriantly at the higher E(h), in the presence of small quantities of oxygen, than at the lower one in the absence of oxygen. P. fluorescens could grow at a relatively low E(h) (40 mv, pH 7.0) in pure culture but not in the presence of C. perfringens under the same conditions.

摘要

开发了一种用于测量E(h)、pH值和细胞数量变化的新仪器。利用该仪器,通过使用产气荚膜梭菌和荧光假单胞菌,在初始E(h)水平为200和40毫伏(pH 7.0)的条件下研究了这些参数之间的关系。在少量氧气存在的情况下,产气荚膜梭菌的一个菌株在较高的E(h)水平下比在无氧的较低E(h)水平下生长得更茂盛。荧光假单胞菌在纯培养中可以在相对较低的E(h)(40毫伏,pH 7.0)下生长,但在相同条件下与产气荚膜梭菌共存时则不能生长。
