一种水体净化细菌的分离鉴定及生理特性分析

Separation and Identification of a Sort of Water Purification Bacteria and Analysis of Its Physiological Characteristics

摘要: 从土壤中分离出一株能够去除水中氨氮的微生物，经过细菌菌落特征分析，显微镜染色实验，菌落呈圆形，乳白色，细胞呈短直杆状，严格好氧，为革兰氏阴性菌。通过接触酶实验、V-P实验、尿素分解等五项生理生化实验结果分析，对比伯杰氏手册，初步鉴定该细菌属假单胞菌属(Pseudomonas)。

Abstract: A microorganism capable of removing ammonia nitrogen from water was isolated from the soil. After the analysis of bacterial colony characteristics and microscopic staining experiments, the bacterial colony was round, milky white, and the cells were short and straight rod-shaped, strictly aerobic, which was gram-negative bacterium. Through the analysis of the results of five physio-logical and biochemical experiments, including enzyme exposure test, V-P test and urea decompo-sition test, the bacteria were preliminarily identified as pseudomonas by comparing the manual of Berger.
