Summary: This study investigates the interaction mechanism between heavy metal Pb2+ and Trichoderma viride. The results show that Pb2+ exhibits toxic effects on T. viride, leading to decreased biomass, pH changes, and structural damage. T. viride can bio-adsorb and bioaccumulate Pb2+ and participate in biomineralization and reduction processes.

Summary: Biological plant protection is a promising alternative to chemical methods for safeguarding plants against diseases, using biological control agents (BCAs) to suppress plant pathogens. While microbial BCAs have the potential to effectively manage crop diseases, there is a need for further research to improve their efficacy. Microbial consortia, consisting of multiple microorganisms with different mechanisms of action, offer promise in enhancing the overall antipathogen effect. This article aims to present an analysis of the current status of microbial consortia-based biocontrol and explore future research directions for biological plant protection.

Summary: Wood inhabiting fungi release volatiles that play an important role in wood decomposition and have activity against other fungi and bacteria. The volatiles of Schizophyllum commune inhibit fungal growth and modify bacterial motility. The microbial community in the mycosphere of S. commune includes Actinobacteria, Proteobacteria, Pseudomonadaceae, Sphingomonadaceae, Erwiniaceae, Yersiniaceae and Mariprofundacea as the dominating families, as well as ascomycetes and basidiomycetes in the fungal community.

Summary: The use of plant growth promoting rhizobacteria (PGPR) is an environmentally friendly way to control plant disease and increase crop yield. PGPR can synthesize pathogen-antagonizing compounds and trigger plant immune responses to suppress diseases, as well as directly stimulate plant growth. Successful biocontrol agents (BCAs) provide strong support for the application of PGPR in greenhouse production, paving the way for their widespread use in agriculture to manage diseases and adapt to climate change conditions.

Summary: Recent studies have shown that there are different microbiomes between disease-suppressive and disease-conducive soils, with keystone species in suppressive soil playing a critical role in disease suppression. Pseudomonas strains, identified as keystone taxa, displayed strong inhibition on pathogens and reduced the incidence of bacterial wilt disease, providing a potential approach for crop protection against pathogen infection.

Summary: Agricultural land is deteriorating due to population increase, urbanization, and industrialization. To increase crop production from smaller areas, high doses of inorganic fertilizers are used, damaging soil health and causing nutrient imbalance. Recent technological advances have shown the benefits of microbial inoculants such as Actinobacteria in replacing harmful chemicals and promoting sustainable farming practices. Actinobacteria have multifunctional traits that promote plant growth, control phytopathogens, solubilize nutrients, produce phytohormones, enhance organic matter decomposition, and suppress soil-borne pathogens.

Summary: Aphytis species are considered important natural enemies in biological control of armoured scale insects. This study identified four characteristic pigmentation patterns of Aphytis pupae, which could be used as important supplementary diagnostic characters. Pupal pigmentation could be helpful in distinguishing closely-related species of Aphytis.

Summary: This study investigated the early response of grapevine to Esca pathogens and identified metabolites that may be associated with the biocontrol activity. The results showed that glycerophospholipids and polyphenol compounds, particularly stilbenoids, may play a role in limiting the development of Esca pathogens in planta. In vitro evaluation also demonstrated antifungal activity of some relevant biomarkers against Phaeomoniella chlamydospora and Botrytis cinerea.

Summary: Plant metabolomics is a discipline that studies plant biochemistry at the molecular level, identifying biochemical characteristics and metabolites. However, this technology is not widely applied in supporting weed biocontrol programs. Understanding plant biochemical phenotypes and the influences of biotic and abiotic factors is crucial for agent selection and non-target identification in weed biocontrol.

Summary: It is claimed that one g of soil holds ten billion bacteria representing thousands of distinct species. These bacteria play key roles in the regulation of terrestrial carbon dynamics, nutrient cycles, and plant productivity. We isolated novel soil bacteria from the soybean rhizosphere, identified their potential as novel species, and demonstrated their ability to promote plant growth and enhance soybean growth under drought stress. Our findings also provide insight into the genetic factors that contribute to plant growth promotion in these bacteria.

Summary: This study investigated the mechanisms induced by P. chlamydosporia in controlling Meloidogyne javanica, a harmful nematode, in tomato plants. The fungus was found to activate defense responses and modify gene expression and metabolite profiles in the host plant, contributing to the control of the nematode. The findings suggest that the interaction between the fungus and the nematode involves the activation of specific pathways and cascades related to plant defense.

Summary: This study isolated potential microorganisms from organic vineyard soils in Spain that have the ability to inhibit fungal growth and mycotoxin production. Among the isolates, Arthrobacter sp., Rhodococcus sp., and Bacillus mycoides showed excellent potential for controlling toxigenic grape fungi. Further research is needed for their possible industrial application as biological control agents.

Summary: The study successfully demonstrated the feasibility of using M1GS technology as a metabolic engineering tool to increase butanol production in Clostridium beijerinckii by knocking down the mRNA levels of CcpA and DisA. This approach led to an improvement in mixed-sugar utilization and solvent production, as well as alterations in c-di-AMP-mediated signaling and cell cycling, ultimately resulting in a sporulation delay and increased solvent production.

Summary: The study investigated a process engineering strategy to effectively convert hydrothermolysis pretreated non-detoxified switchgrass hydrolysates to acetone butanol ethanol (ABE) using a metabolically engineered strain of Clostridium beijerinckii. Through modifications to the engineered strain and the use of intermittent feeding, ABE fermentation was enhanced and detoxification of the hydrolysates prior to fermentation was eliminated. The ABE production from the non-detoxified hydrolysates by the engineered strain was comparable to the control medium, demonstrating the potential of this strategy in improving biofuel production.
