4-氨基苯酚等芳香族化合物对环境有毒性，应有效消除。芳香族化合物的生物降解是一种高效、环保的技术，因为添加选定的微生物不会增加任何类型的污染物，即使是最难降解的污染物也能被有效地去除。对假单胞菌的药效进行了研究。对菌株ST-4在不同pH、温度和葡萄糖条件下对4-氨基苯酚的降解进行了研究，筛选出了最大限度降解4-氨基苯酚的最佳条件。假单胞菌对4-氨基苯酚的最大生物降解率菌株ST-4在pH值为8、温度为30℃、葡萄糖浓度为15 mM的条件下培养72 h。
Aromatic compounds such as 4-aminophenol are toxic to the environment and thus should be eliminated effectively. Biodegradation of aromatic compounds is an efficient and environment friendly technique as addition of selected microbes does not add any kind of pollutants and actively remove even the most recalcitrant pollutants. We investigated the effectiveness of Pseudomonas sp. strain ST- 4 in the biodegradation of 4-aminophenol under variable pH, temperature and glucose regimes and sorted out optimum conditions for maximum biodegradation of 4-aminophenol. Maximum biodegradation of 4-aminophenol by Pseudomonas sp. strain ST- 4 was observed at pH 8, temperature 30°C and glucose concentration of 15 mM at 72 h, respectively.
