Harnessing landfill-derived Bacillus subtilis (LLS-04) for bio-electrodegradation of di-butyl phthalate: Comprehensive toxicity assessment across multiple biological models.
AI summary Read the abstract
A landfill-derived Bacillus subtilis strain (LLS-04) achieved 98.57% degradation of di-butyl phthalate (DBP) through bio-electrodegradation, significantly outperforming biodegradation or electrodegradation alone. Comprehensive toxicity assessments confirmed that the treated effluent was substantially less toxic than untreated DBP waste.
Di-butyl phthalate (DBP), a pervasive environmental contaminant, poses significant ecological and health risks due to its persistence and toxicity. This study investigates the potential of a landfill-derived Bacillus subtilis strain (LLS-04) in bio-electrodegradation of DBP, alongside a comprehensive toxicity assessment across multiple biological models. Bio-electrodegradation efficiency was compared to biodegradation and electrodegradation, revealing that bio-electrodegradation achieved a remarkable 98.57 % reduction in DBP concentration significantly outperforming the other methods. This enhanced degradation was attributed to improved microbial activity and enzyme production, as indicated by higher protein content and increased esterase and dehydrogenase activities in the bio-electrodegradation system. The optimized conditions facilitated efficient degradation, with HPLC-MS/MS analysis confirming the breakdown of DBP into non-toxic end products via a proposed metabolic pathway. A comprehensive toxicity assessment, including in-silico analysis, in-vitro cytotoxicity and brine shrimp lethality assays, demonstrated a significant reduction in toxicity of BES treated effluent compared to DBP untreated effluent. Furthermore, in-vivo toxicity studies using animal model supported these findings, demonstrating reduced toxicity in the BES treated effluent compared to the DBP untreated effluent. Overall, these findings highlight the potential application of bio-electrodegradation in bioremediation strategies for phthalate pollution, offering an effective solution for reducing both DBP concentration and its environmental toxicity.

Heavy Metal-Resistant, Plastic-Degrading Bacillus sp. Isolated from Landfill Leachate: Identification and Characterization
AI summary Read the abstract
Researchers isolated bacteria from Dhaka landfill leachate that simultaneously resist heavy metals and degrade polyethylene, finding a statistical correlation between these traits and identifying resistance genes that spread via horizontal gene transfer. This discovery matters for microplastic research because it reveals that plastic-polluted environments are selecting for novel microbial capabilities, and such bacteria may offer bioremediation pathways for both plastic and metal co-contamination.

Exploring Potent Fungal Isolates from Sanitary Landfill Soil for In Vitro Degradation of Dibutyl Phthalate
AI summary Read the abstract
Researchers isolated fungal strains from sanitary landfill soil and tested their ability to break down dibutyl phthalate, a widely used plasticizer. The most effective isolate, identified as Aspergillus flavus, degraded over 99% of the plasticizer within 15 days by producing esterase enzymes. This is the first report of this fungal species using dibutyl phthalate as its sole carbon source, suggesting potential for bioremediation of plasticizer-contaminated soils.
