Abstract

A bacterial strain (strain S5) which grows aerobically with the sulfonated azo compound 4-carboxy-4'-sulfoazobenzene as the sole source of carbon and energy was isolated. This strain was obtained by continuous adaptation of "Hydrogenophaga palleronii" S1, which has the ability to grow aerobically with 4-aminobenzenesulfonate. Strain S5 probably cleaves 4-carboxy-4'-sulfoazobenzene reductively under aerobic conditions to 4-aminobenzoate and 4-aminobenzene-sulfonate, which are mineralized by previously established degradation pathways.

摘要

分离出了一种细菌菌株(菌株S5),它能以磺化偶氮化合物4-羧基-4'-磺基偶氮苯作为唯一碳源和能源进行有氧生长。该菌株是通过对“嗜氢噬纤维菌”S1进行连续驯化获得的,“嗜氢噬纤维菌”S1能够以4-氨基苯磺酸盐进行有氧生长。菌株S5可能在有氧条件下将4-羧基-4'-磺基偶氮苯还原裂解为4-氨基苯甲酸和4-氨基苯磺酸盐,它们通过先前建立的降解途径被矿化。
