摘要
从土壤中分离筛选出以甲苯为惟一碳源的5种细菌菌株,测定菌体浓度随时间变化曲线,以较优菌种ZD5作为出发菌株进行紫外诱变,获得优势诱变菌株ZD5A.初步鉴定菌株ZD5A为假单胞菌,命名为Pseudomonassp.ZD5A.得出甲苯降解和菌体浓度变化有相关性,且这种较简便降解挥发性有机废气的菌种评选方法是可行的.
Toluene has induced some diseases,screening of bacterial strains is necessary for toluene biodegradation. Five toluene biodegradation strains were isolated and screened from soil, and the time course of the bacteria growth were also determined. Strain ZD5A obtained by UV mutation of ZD5 showed the superiority. Through preliminary, identification, it was named as Pseudomonas sp. ZD5A. The results showed that toluene biodegradation was related with bacteria growth. Furthermore, this method is feasible.
