Summary: This study investigated the control and immobilization mechanisms of rhizosphere microorganisms on heavy metals. The results showed that heavy metals inhibited the ability of rhizosphere bacteria to promote plant growth, but stimulated the production of certain substances and biofilm formation, thereby enhancing the removal efficiency of heavy metals. Different bacteria had different mechanisms for immobilizing heavy metals. This study revealed the potential application prospects of biofilm bacteria in heavy metal remediation.

Summary: Electrical instruments generate a large amount of electronic waste (estimated to reach 74.7 million tonnes by 2030), posing a threat to human life and the environment due to its hazardous nature. Therefore, proper e-waste management is necessary. This study explores the use of bio-metallurgy and investigates simultaneous leaching of metals using indigenous heterotrophs and autotrophs. The experiments showed high recovery efficiencies for copper, zinc, and nickel, with significant differences in metal concentrations depending on the bacterial group (P < 0.05).

Summary: In this study, microbe-produced thiosulfate was used as a novel lixiviant in bioleaching of precious metals from discarded TPCBs. The effects of important parameters on the selective production of thiosulfate and sulfate were investigated. The results showed that adjusting the pH and adding an inhibitor led to an overproduction of thiosulfate and a decreased sulfur oxidation rate to sulfate. Optimum conditions for thiosulfate bioleaching achieved 100% copper dissolution and successful recovery of gold and silver.

Summary: A FeCu@PC-800/6 catalyst was successfully prepared and demonstrated efficient catalytic activity for sulfamethazine (SMT) removal at a low dose of 25.0 mg L-1. Experimental and DFT calculations suggested that Hetero-EF reactions were enhanced by internal-microelectrolysis, where Cu-0 promoted electron transfer between Fe-0 and PC while Cu+ facilitated H2O2 decomposition and Fe3+/Fe2+ cycling. The catalyst showed cost-effectiveness and could be reused after thermal treatment, showcasing high efficiency for organic contaminants degradation through the EF process.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
