Abstract:
In this study, the H2S donor, sodium hydrosulfide (NaHS) was used to pretreat Phanerochaete chrysosporium in order to improve its ability to degrade 2,4-dichlorophenol (2,4-DCP). When pretreated with 100μM NaHS, P. chrysosporium was able to degrade 2,4-DCP completely in 24h, whereas the degradation efficiency of the untreated control was only 57%. The 2,4-DCP-induced oxidative stress was alleviated by NaHS, and the percentage of surviving cells increased by 32%. H2S or HS(-), rather than other compounds derived from NaHS, were responsible for promoting 2,4-DCP degradation by P. chrysosporium. The results of this study suggest that H2S treatment is a potential strategy to alleviate environmental stress and improve the efficiency of the biological removal of pollutants from wastewater.
