Abstract

The coliform flora of a pulp and cardboard mill that uses birch as the raw material and ammonium sulphate as the process chemical was studied. Escherichia coli was observed to multiply in the mill. It persisted as the dominant thermotolerant coliform in the effluent. Klebsiellae were encountered among total coliforms only. The E. coli strains isolated had the biochemical characteristics and maximum growth temperatures typical to the species. However, serotyping and hemolysin test differentiated these strains from pathogenic and fecal E. coli.

摘要

对一家以桦木为原料、硫酸铵为工艺化学品的纸浆和纸板厂的大肠菌群进行了研究。观察到大肠杆菌在该厂中繁殖。它作为优势耐热大肠菌群在废水中持续存在。仅在总大肠菌群中发现了克雷伯氏菌。分离出的大肠杆菌菌株具有该物种典型的生化特征和最高生长温度。然而，血清分型和溶血素试验将这些菌株与致病性大肠杆菌和粪便大肠杆菌区分开来。
