Summary: This study investigated the effects of nitrogen fertilization under different water availability conditions on soil microbial biomass and composition. The results showed that nitrogen fertilization had a stronger impact on soil microbial biomass and composition compared to water regime. Especially under low soil water availability, nitrogen fertilization increased soil microbial biomass and altered the composition of soil microbial communities.

Summary: Potato domestication has altered the host response to its rhizosphere microbiome in nutrient-dependent ways. Taxonomically similar rhizosphere microbial communities between potato clades resulted in different host responses to microbes. However, studies testing how crop domestication-driven differences in rhizosphere microbial communities affect plant health are limited mostly to specific symbiont pairings.

Summary: Increasing microbial richness can improve plant biomass accumulation, indicating that diversity effects are stronger than single-strain effects. However, high antagonistic intensity between diverse microbes may have a consistent negative effect on plant growth, without altering positive BEF relationships.

Summary: This study examined the spatial distribution of soil microbial biomass and their metabolic nutrient limitations in mountain peatlands at different altitudes. The results showed that soil microbial PLFAs were higher in the sedge-dominated peatlands than in the shrub/Sphagnum-dominated peatlands. The soil microbial PLFAs in the sedge-dominated peatlands increased at high altitudes but decreased with altitude in the shrub/Sphagnum-dominated peatlands. The limitations on soil microbial metabolism were primarily controlled by soil physical properties and nutrient ratios.

Summary: Nonmycorrhizal root-colonizing fungi play a significant role in plant growth by affecting nutrient uptake and immune response. This study shows that diverse nonmycorrhizal fungi can consistently promote plant growth across different habitats, but not by enhancing nutrient uptake.

Summary: The potential of fungi and bacteria for residual C transformation depends on residue quality, with high-quality residues (such as grains) being strongly affected by soil disturbance. Conversely, few tillage-facilitated effects occur with a decline in substrate quality (such as leaves and roots).

Summary: Three fungal strains isolated from oily sludge contaminated soil, including Trichoderma atroviride, Aspergillus nidulans, and Aspergillus sydowii, were found to have the potential to degrade aliphatic hydrocarbons/crude oil. The degradation of aliphatic hydrocarbons was more efficient during the initial days of incubation (15 days) as compared to 30 days.

Summary: Intermingled uninfected and root-knot nematode-infected tomato plants were studied under protected cultivation. Rhizobacteria were isolated from the rhizosphere of these plants, and it was found that the nematicidal potential of rhizobacteria from uninfected soil was higher than that from infected soil. Certain strains of rhizobacteria showed effectiveness in reducing nematode penetration and reproduction in tomato plants.

Summary: Bacteria release volatile organic compounds (VOCs) into the environment, which have various effects on plants, including promoting growth, suppressing pathogens, and acting as signaling molecules. Some VOCs also exhibit antimicrobial and pesticidal activities. Different bacterial species produce different VOCs, with some contributing to plant growth promotion. Understanding the mechanisms by which VOCs affect plant genes and metabolic pathways is still a topic of ongoing research.

Summary: A passive composting method using a hybrid Bacillus commune and cow dung slurry for municipal solid waste was investigated, where four Bacillus strains were mixed with cow dung in different ratios. The temperature (ambient and pile) triggered physico-chemical changes in the compost mix, and the quality of the finished compost was tested after two seasons. Adding Bacillus commune and cow dung slurry during the peak summer season accelerated degradation and resulted in enriched compost. Various parameters such as color, pH, C/N ratio, organic carbon, conductivity, density, NPK availability, and phytotoxicity assays justified the effectiveness. Microbial diversity and suitable seasonal conditions play an important role in the waste degradation process and compost maturity.

Summary: This study analyzed the effect of granulation on the physico-functional properties of 'Itaborai' sweet orange. The results showed that granulated juice sacs had a thicker cell wall and higher respiration rate compared to healthy fruit. Granulated citrus juice sacs contained a higher amount of galacturonic acid and had diminished β-glucosidase activity, resulting in cellulose deposition. Additionally, healthy fruit exhibited higher ferrous ion-chelating activity and lower lipoxygenase activity than granulated fruits. The study suggests that granulation might be related to pectin metabolism.

Summary: This study investigated the effects of diazotrophic cyanobacteria on fruit quality attributes in tomato plants under elevated CO2 conditions. The results showed that cyanobacterial inoculation significantly increased soil microbiological parameters, plant growth attributes, and antioxidant/defense enzyme activities, resulting in higher yields and better-quality parameters of tomatoes, particularly under elevated CO2 conditions. This suggests that cyanobacterial inoculants have the potential to promote tomato crop production and improve fruit quality in the context of climate change.
