Summary: Paenibacillus polymyxa strain J2-4 exhibited high fumigant activity against Meloidogyne incognita, with VOCs showing strong nematicidal effects on juveniles and eggs. Commercial VOCs such as 2-isobutyl-3-methylpyrazine and 2-dodecanone demonstrated significant reduction in root galls and egg masses, providing potential biocontrol agents for managing root-knot nematodes.

Summary: The study demonstrates that the biocontrol efficacy of P. polymyxa LMG27872 against the root-knot nematode M. incognita in tomato is dose-dependent. In in vivo experiments, a high dose of P. polymyxa LMG27872 can effectively inhibit the development and reproduction of the nematode, leading to a significant reduction in parasitism on tomato plants. Additionally, P. polymyxa LMG27872 has a negative effect on tomato growth, but this effect disappears when the plants are challenged by the nematode, indicating a tolerance or defense priming mechanism.

Summary: Tomato plants are susceptible to infection by plant-parasitic nematodes, but the biosynthesized selenium nanoparticles show potential as a cost-effective and environmentally friendly biocontrol agent for RKN management in tomato plants. The nanoparticles significantly reduced the number of galls, egg mass, and eggs/egg mass of the nematode, and improved tomato growth and enzyme activity.

Summary: The root-knot nematode is a damaging pest in vegetable crops globally. The continuous use of nematicide has negative impacts on human and environmental health. To reduce nematicide usage, eco-friendly integrated nematode management is necessary. Trichoderma, an antagonistic fungus, has shown efficacy in controlling root-knot nematode. The strain Trichoderma asperellum FbMi6 exhibited significant nematicidal activity and when enriched in neem cake, it increased okra yield and decreased nematode population.

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.
