Summary: In this study, glycerol was used as a co-substrate for the biodegradation of DBT by Paraburkholderia sp. C3. The research found that using more readily metabolized substrates can increase the biodegradation rate of PAHs, and confirmed the correlation between polyhydroxyalkanoate granule formation and the enhancement of DBT biodegradation induced by glycerol.

Summary: The genomes of Pseudomonas aeruginosa S3, Sphingobacterium S2, and Geobacillus EC-3, isolated from compost, were annotated to understand their ability to degrade poly(lactic acid) (PLA). The draft genomes revealed catabolic genes for biodegradation of xenobiotics, aromatic compounds, and lactic acid, as well as genes related to biofilm formation and regulation. These isolates possess essential genetic elements for PLA metabolism at both mesophilic and thermophilic temperatures.

Summary: Denisova Cave in southern Siberia is the type locality of the Denisovans, an archaic hominin group who were related to Neanderthals. The cave yielded hominin remains from different groups, indicating it was a contact zone between Neanderthals and Denisovans. The study reveals that Denisovans and Neanderthals repeatedly occupied the site, with modern human DNA appearing in the sediments at least 45,000 years ago.

Summary: The study investigated the effects of plasticizers on the properties and biodegradability of potato-based bioplastic, revealing that plasticized films were more flexible with lower tensile strength and higher elongation at break value. The addition of plasticizers effectively reduced the swelling and water retaining capacity of potato-based biodegradable plastic films.

Summary: This study found that ACE could be completely mineralized under enriched consortia coupled with nitrate reduction, and identified three novel ACE-degrading strains capable of degrading ACE under both aerobic and anoxic conditions. Plasmid-mediated ACE biodegradation was suspected, and a total of 83 near-complete metagenome-assembled genomes (MAGs) were obtained, suggesting Proteobacteria and Bacteroidetes as the dominant phyla in ACE-degrading consortia.

Summary: The researchers developed a supervised multi-modal deep learning model to predict tissue/cell type-specific promoter-enhancer (PE) and promoter-promoter (PP) interactions. The model utilized a comprehensive set of features, including genomic sequence, epigenetic signal, anchor distance, evolutionary features, and DNA structural features. The proposed approach outperformed state-of-the-art deep learning methods, especially in predicting PE interactions. The performance could be further improved by using computationally inferred biologically relevant tissues/cell types in the pretraining.

Summary: This study assesses the impact of PVA-based polymers in marine environments, focusing on biodegradation and aquatic toxicity. Results show that the biodegradation of PVA in marine conditions is negligible without an acclimated inoculum, and slightly improves when combined with glycerol. The toxicity of pure PVA is almost negligible, but slightly increases when glycerol is added to the material.

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.
