摘要: 通过对两类不同培养基上分离的土壤细菌的生理特征的比较,发现两组细菌的种群有所不同.芽孢杆菌主要生长在宫营养的培养基上,而很难在低营养的培养基上生长.假单孢杆菌和棒杆类型的细菌则在两类培养基上均可生长.这与两类细菌对环境的适应能力有关.

Abstract: Through comparing the physiological characteristics of soil bacteria isolated from two different media, a significant difference between two populations of bacteria is found. Bacillus sp. mainly grows on rich medium and hardly on poor one, but Pseudomonas sp. and stick like bacteria can grow on the both, which is related to the different adaptability ofbacteria to the environment.
