在微好氧条件下，观察到脱色希瓦氏菌S12对偶氮染料耐酸性红GR的完全生物降解。厌氧条件下脱色率最高，好氧条件下生物量最大，但只有在微好氧条件下，脱色产物才能进一步生物降解。在微需氧条件下，S.脱色菌S12可以利用乳酸、甲酸、葡萄糖和蔗糖等多种碳源进行偶氮染料脱色，其中乳酸是最佳碳源。在固酸性红GR的生物转化过程中，没有检测到磺化芳香胺，而有H（2）S生成。根据GC-MS和HPLC分析结果，脱色产物苯胺、1，4-二氨基苯和1-氨基-2-萘酚通过邻苯二酚和4-氨基苯甲酸被完全生物降解。
The complete biodegradation of azo dye, Fast Acid Red GR, was observed under microaerophilic conditions by Shewanella decolorationis S12. Although the highest decolorizing rate was measured under anaerobic condition and the highest biomass was obtained under aerobic condition, a further biodegradation of decolorizing products can only be achieved under microaerophilic conditions. Under microaerophilic conditions, S. decolorationis S12 could use a range of carbon sources for azo dye decolorization, including lactate, formate, glucose and sucrose, with lactate being the optimal carbon source. Sulfonated aromatic amines were not detected during the biotransformation of Fast Acid Red GR, while H(2)S formed. The decolorizing products, aniline, 1,4-diaminobenzene and 1-amino-2-naphthol, were followed by complete biodegradation through catechol and 4-aminobenzoic acid based on the analysis results of GC-MS and HPLC.
