Sulfonated Azo Dyes

Sulfanilic acid is a representative intermediate of some sulfonated azo dyes. A bacterial strain isolated from the river in Wenzhou, could utilize sulfanilic acid as the solo carbon source and energy source. Based on its morphological, physiological and biochemical characteristics as well as 16SrRNA sequences the bacterial strain was identified as Ochrobactrum anthrop. Effective biodegradation of sulfanilic acid occurred at pH ranging from 6 to 8. The optimum growth temperature and pH for the bacterial strain to utilize sulfanilic acid are 30°C and 7.0 respectively. Its most favorable sulfanilic acid concentration is 300mg/L.

A bacterial strain CQH-1 capable of mineralizing iprodione was isolated and characterized. On the basis of its morphological, physiological, and biochemical characteristics combined with phylogenetic analysis of its 16S rRNA gene sequence, strain CQH-1 was identified as a Microbacterium sp. CQH-1. It was able to use iprodione and 3,5-dichloroaniline as the sole source of carbon and energy for its growth. It completely degraded 100 mg·L−1iprodione within 96 h at 30 °C. During the degradation of iprodione by strain CQH-1, 2 compounds were detected in GC–MS analysis and were recognized as N-(3,5-dichlorophenyl)-2,4-dioxoimidazolidine and 3,5-dichloroaniline. So, the biodegradation pathway of iprodione by strain CQH-1 was proposed. This is the first report of an iprodione-mineralizing strain from the genus Microbacterium, and strain CQH-1 might be a promising candidate for application in the bioremediation of iprodione-contaminated environments.
