红球菌chr-9降解吡啶和苯酚的特性
DOI: 10.3724/SP.J.1145.2012.00647, PP. 647-650
Keywords: 红球菌,吡啶,苯酚,生物降解,协同降解
Abstract:
研究了红球菌（rhodococcus）chr-9菌株在基础盐培养基中降解吡啶和苯酚的特性，分析了菌株降解苯酚和吡啶间的差异.结果表明，菌株chr-9能够在72h内将基础盐培养基中的吡啶（200mgl-1）和苯酚（200mgl-1）完全降解，同时利用吡啶和苯酚进行生长.菌株降解吡啶的最适温度为35℃，最适ph为8.0.菌株降解吡啶和苯酚的速度与底物的初始浓度呈负相关；在无其它氮源的基础盐培养基中，菌株能够利用吡啶和苯酚协同生长.图7参12
