Abstract

Bacillus stearothermophilus BR219, isolated from river sediment, degraded phenol at levels to 15 mM at a rate of 0.85 mumol/h (4 x 10(6) cells). The solubilized phenol hydroxylase was NADH dependent, exhibited a 55 degrees C temperature optimum for activity, and was not inhibited by 0.5 mM phenol.

摘要

从河流沉积物中分离出的嗜热脂肪芽孢杆菌BR219，能以0.85微摩尔/小时（4×10⁶个细胞）的速率降解高达15毫摩尔浓度的苯酚。溶解的苯酚羟化酶依赖于NADH，活性的最适温度为55℃，且不受0.5毫摩尔苯酚的抑制。
