Biodegradation of hazardous aromatic compounds is emerging as a potential tool for reduction of environmental pollution due to their high toxicity and complex synthetic nature. In this study textile effluent was used as a microbial source for aerobic degradation of sulfanilic acid. Two adaptation techniques were followed to maximize uptake of sulfanilic acid, provided as a carbon and nitrogen source. The continuous enrichment and acclimatization media techniques were carried out for 20 days, respectively and both samples were screened for better degradation efficiency. The isolates were found to be similar to the colonies obtained from effluent. Sulfanilic acid degrading organism was identified as Bacillus cereus AAA2018 using 16S rRNA sequencing. Similarly, study was done for fungal strain Aspergillus japonicas. The bacterial strain showed subsequent reduction of sulfanilic acid at minimal salt concentration, whereas A. japonicus showed very little degradation efficiency comparatively. The comparative study of biodegradation capacity of sulfanilic acid was confirmed using GCMS in which product degradation profile of both bacterial and fungal strains included Dimethyl sulfoxide (DMSO) and Phenol 2,4-bis(1,1-dimethyethyl) which gives an explanation for decrease in growth of bacterial culture as DMSO act as strong antibacterial agent.

使用蜡状芽孢杆菌AAA2018从纺织工业废水污染土壤中生物降解磺胺酸

由于其高毒性和复杂的合成性质，危险性芳族化合物的生物降解正成为减少环境污染的潜在工具。在这项研究中，纺织废水被用作微生物源，好氧降解磺胺酸。遵循了两种适应技术，以最大限度地吸收作为碳和氮源的磺胺酸。连续富集和驯化培养基技术分别进行了20天，并对两个样品进行了筛选以提高降解效率。发现分离物与从流出物中获得的菌落相似。使用16S rRNA测序将磺胺酸降解生物鉴定为蜡状芽孢杆菌AAA2018。同样，对真菌菌株进行了研究日本曲霉。细菌菌株显示出在最小盐浓度下随后磺胺酸的还原，而日本刺槐相对显示出非常小的降解效率。使用GCMS确认了对磺胺酸生物降解能力的比较研究，其中细菌和真菌菌株的产物降解曲线均包括二甲基亚砜（DMSO）和苯酚2,4-双（1,1-二甲基乙基），这为降低降解提供了解释在细菌培养的生长中，DMSO充当强抗菌剂。
