Biodegradation of nicosulfuron by a Talaromyces flavus LZM1

► This is the first study to report that a Talaromyces species could degrade nicosulfuron. ► Talaromyces flavus LZM1 could degrade nicosulfuron over a broad range of temperature and pH levels. ► Response surface methodology based on the Box–Behnken design was used to optimize the parameters. ► Metab...

description: ► This is the first study to report that a Talaromyces species could degrade nicosulfuron. ► Talaromyces flavus LZM1 could degrade nicosulfuron over a broad range of temperature and pH levels. ► Response surface methodology based on the Box–Behnken design was used to optimize the parameters. ► Metabolites from nicosulfuron degradation were identified by LC–MS, and a possible degradation pathway was deduced. The fungal strain LZM1 was isolated from activated sludge and found to be capable of utilizing nicosulfuron as the sole nitrogen source for growth. Based on morphological and internal transcribed spacer evaluations, LZM1 was identified as a Talaromyces flavus strain. Under optimum conditions (pH 6.1, 29°C), T. flavus LZM1 degraded 100% of the initially added nicosulfuron (100mgL–1) within 5d. T. flavus LZM1 was also found to be highly efficient in degrading tribenuron methyl, chlorsulfuron, bensulfuron methyl, ethametsulfuron methyl, cinosulfuron, and rimsulfuron....
