Summary: This study investigated the effects of adding pig manure and microbial agents on the performance and product quality of laboratory-scale composting of vegetable waste, and analyzed the succession of the microbial community during composting. The results showed that the addition of pig manure and microbial agents accelerated composting, enhanced organic carbon degradation, and promoted compost maturation. The addition of these additives also increased enzyme activity, reshaped the microbial community, and reduced the relative abundance of potential animal and plant pathogens. Specific microbial taxa were enriched in different stages of composting and played important roles in compost maturation.

Summary: This review discusses the application of microbial inoculation in agro-industrial waste composting and its role in improving the composting process and compost quality. The addition of microorganisms can accelerate the degradation and mineralization of organic matter, enhance microbial enzyme activities, and improve the quality of the final products. It also reduces the production cost. In pilot-scale and industrial-scale productions, sludge's microbial consortium can effectively enhance the composting process.

Summary: This study investigated the changes in the protist community during composting and found that phagotrophic protists play a significant role in the composting process. The protist community structure varied among different phases, and it was influenced by NO3- and NO2- concentrations as well as the bacterial community.

Summary: Anthropogenic disturbance on natural ecosystems is increasing, affecting all components of the ecosystems. A metacommunity framework is needed to understand the response of different biocoenosis types to human disturbance. Through advanced molecular techniques, sediment communities of Fungi, Bacteria, and Archaea in Italian show caves were investigated to unravel the effects of tourism on their diversity and identify changes in the driving forces of community composition. The study showed that cave tourism directly affects the community of Bacteria and indirectly influences Fungi and Archaea.

Summary: This study investigated the changes in TBBPA and Cu concentrations and microbial community responses in co-contaminated sediments during long-term incubation. Fungal communities showed a stronger response to pollutant addition after a long incubation compared with bacterial and archaeal communities. Bacterial, archaeal, and fungal microbial communities were distinctly distributed into two separated clusters according to incubation time, indicating temporal changes in response.

Summary: This study investigates the relationships among the relative abundance of guild-plant pathogenic fungi, compost maturation index, and microbial community variation during vegetable waste composting, influenced by the C/N ratio. The results show that the treatment with a C/N ratio of 15 (CN15) has greater microbial community variation and a better overall compost maturation index value compared to the treatment with a C/N ratio of 25 (CN25). However, the CN25 treatment experiences a greater decline in plant-pathogenic fungi compared to the CN15 treatment. It is suggested that moderately delayed maturation of composting is beneficial for reducing guild-plant pathogenic fungi in vegetable waste.

Summary: This study investigated the effects of different concentrations of low-density polyethylene microplastics on the chemical properties and bacterial communities of agricultural soil. The results showed that higher concentrations of microplastics significantly altered soil electrical conductivity and exchangeable cation content, and also had an impact on bacterial abundance and diversity, potentially affecting the ecological functions of soil ecosystems.

Summary: This study analyzed the bacterial and fungal structures in Cu/TCH-amended composting and found that Cu and TCH had a significant impact on fungi but not on bacteria. TOC and TN were identified as the primary controls on microbial diversity, with NH4+-N and NO3--N being more beneficial to fungi.

Summary: Our study used metagenomics and sequencing techniques to investigate the fungal diversity in mesophilic and thermophilic environments during composting of sewage sludge, cow manure, and wheat straw. We found enhanced microbial activity in the thermophilic phase, while the beta-glucosidase enzyme activity was higher in the mesophilic zone. The range of alpha-diversity values was greater in the mesophilic habitats, and specific fungal types were more abundant in each environment.

Summary: This study investigated the bacterial and fungal diversity during composting of textile waste, finding Proteobacteria, Bacteroidetes, and Actinobacteria to be dominant in the mesophilic phase but not in the thermophilic phase. Despite the sustained thermophilic profile of composting textile waste, fungi were observed during the thermophilic phase. Rozellomycota, Basidiomycota, and Ascomycota were the most dominant phyla during both composting phases, suggesting their potential for bioaugmentation to improve the maturity level of textile waste compost.

Summary: This study investigates the impact of different cropland management systems on microbial diversity in soil during the transition period from winter to summer. The results show that bacteria and fungi respond differently to seasonal changes, and the changes in diversity between treatments do not sync with each other. The complex interaction between land management and sampling time affects bacterial diversity more than fungal diversity. It is suggested that assessing fungal diversity between management practices can be done without considering temporal variation.

Summary: The conversion of organic matter and phosphorus during the composting process of vegetable waste is influenced by the addition of microbial inoculants. This study investigated the effects of straw-decomposing microbial inoculant (SDMI) on the stability of organic matter and activation of phosphorus in the composting of vegetable waste. The addition of SDMI promoted the degradation of dissolved organic carbon, improved phosphorus stability, and enhanced the thermal stability of organic matter. The results showed that stable forms of phosphorus, such as aluminum phosphate and iron-containing phosphate, were the main forms of phosphorus in the final compost. These findings provide a basis for producing high-quality vegetable compost products and improving the reutilization potential of vegetable waste.

Summary: In the study, it was found that treatment with the last-resort antibiotic polymyxin B caused continuous variations in tolerance among different clinical isolates of Acinetobacter baumannii. The activity of superoxide dismutase (sodB) was identified as a major contributor to the tolerance of A. baumannii to polymyxin B. Rifampicin was effective in eradicating polymyxin B-induced A. baumannii persisters by increasing the generation of reactive oxygen species (ROS), which was linked to significant downregulation of sodB. The combination of polymyxin B and rifampicin was proposed as an effective antipersister strategy in clearing polymyxin B-induced A. baumannii persisters.

Summary: Gaurav et al. report a synergistic interaction between nalidixic acid and tetracycline against multi-drug resistant bacteria Acinetobacter baumannii and Escherichia coli. They find that this synergy does not work for clinical isolates susceptible to antibiotics, suggesting the potential application of nalidixic acid and tetracycline against the emergence of multi-drug resistant bacteria.
