The biotransformation of arsenic by spent mushroom compost – An effective bioremediation agent

Efficacy of Bioadmendments in Reducing the Influence of Salinity on the Bioremediation of Oil-Contaminated Soil

“…The use of biochar and SMC successfully influenced the microbial communities, leading to the remediation of contaminants. Previous studies have shown that these materials can impact microbial communities in contaminated soil through three main mechanisms: (1) effects on the soil environment, including improvements in soil structure, water retention, aeration, nutrient availability, pH, and electrical conductivity (Hu et al, 2021); (2) effects on contaminants, such as immobilisation through surface sorption and complex formation by biochar, as well as the provision of microbial shelter, changes in enzyme activity, and facilitation of electron transfer (Zhu et al, 2017); and (3) effects of spent mushroom compost, including sorption of contaminants, provision of enzymes, and serving as a rich source of microorganisms and organic matter to enhance microbial activity in the soil (Dabrowska et al, 2021;Sun et al, 2021). Moreover, the clustering of some saline soils with non-saline soils at 60 and 120 days indicates the effectiveness of the treatments in mitigating the impact of soil salinity, particularly in the case of biochar treatments (RHB and WSB) in saline soils.…”

Recent Advancements in Microbial Polysaccharides: Synthesis and Applications

“…Sulfate-reducing bacteria (SRB) are a common form of bacteria contained in metal-contaminated wastewater. This bacterial group is successful in the anaerobic oxidation of many organic compounds and the removal of wastewater heavy metals [ 195 , 196 ]. Bacteria such as enterobacter and pseudomonas can breakdown or absorb hazardous heavy metals during bioremediation methods [ 197 , 198 ].…”
