Summary: The isolated strain Lysinibacillus HST-98 shows promising results in reducing Cr(VI) pollution, even at high concentrations. Optimal growth conditions for the strain include a pH of 8-9, a temperature of 36 degrees Celsius, and sodium lactate as an electron donor. Coexisting metal ions like Cu2+, Co2+, and Mn2+ enhance Cr(VI) reduction, while Zn2+, Ni2+, and Cd2+ have the opposite effect. The reduction mechanism of strain HST-98 is primarily mediated by intracellular enzymes, and the genes and enzymes related to chromium metabolism in this strain have been annotated to further understand its mechanism.

Summary: This study focused on investigating the mechanism of chromate reduction and found that the Rhizobium pusense CR02 strain exhibited high resistance to Cr(VI). Extracellular and intracellular chromate reductases were involved in the reduction process. The extracellular polymeric substances produced by the strain enhanced the reduction activity. Furthermore, treatment of CMQW with the bacterial isolate reduced chromosomal aberrations in root cells. These findings suggest the potential application of Rhizobium pusense CR02 for Cr(VI) detoxification.

Summary: Adding nitrogen-retaining microbial agents can effectively reduce heavy metals content in husbandry waste, prolong the high-temperature period, and increase total nitrogen content in composting. Microbial activity-driven pH and NH4+-N changes are the main reason for decreasing heavy metals bioavailability. Nitrogen-retaining microbial agents can also enhance the abundance of resistant bacterial groups and resistance genes, regulating microbial composition during composting.
