Summary: This study aimed to investigate the impact of moisture content and temperature on fungal growth in rice under different storage conditions. The results showed that high temperature and moisture were favorable for the growth of dominant strains, and PCR-DGGE could identify some uncultured strains. This study provides a foundation for understanding the evolution of fungal flora in rice during storage in China and may contribute to the development of biological control methods for preventing mold contamination in rice.

Summary: In recent decades, hydrocarbon concentrations in soil and water have increased due to accidents or operations involving crude oil and petroleum input into the environment. Bioremediation has emerged as an effective environmental recovery approach, utilizing hydrocarbon compounds as growth substrates for microorganisms, contributing to the stabilization of impacted areas.

Summary: This study evaluated the effectiveness of natural attenuation, microbial remediation, phytoremediation, and microbial-phytoremediation in degrading petroleum hydrocarbons. The findings showed that the roots of the plant absorbed small amounts of polycyclic aromatic hydrocarbons, resulting in changes in the soil microbial community structure. The abundance of petroleum-degrading bacteria and plant growth-promoting rhizobacteria increased, along with microbial diversity.

Summary: This study assessed arbuscular mycorrhizal fungi (AMF) diversity in cereal species roots exposed to aluminum phytotoxic levels at different plant phenological stages. The results suggest that AMF diversity based on OTUs analyses depends on cereal plant phenological stage and aluminum supply, which is relevant for developing management strategies for acidic soils.

Summary: This study investigates the biodegradation and impact of SMX in high altitude soils, showing lower degradation compared to lowland soils. SMX significantly alters the structure and composition of soils at high altitudes, with Actinobacter phylum showing high sensitivity to SMX. The presence of SMX resistance genes appears to be related to irrigation with wastewater carrying the studied resistance genes.

Summary: This study evaluated the agronomic, microbiological, and nutritional characteristics of quinoa and amaranth seeds grown in Southern Italy. The results showed that all seeds, regardless of the geographical area of production, were contaminated with yeasts, moulds, and spore-forming bacteria. Bacillus spp. must be strongly monitored as their presence in quinoa and amaranth seeds could result in economic losses for the bread production industry.

Summary: This study aims to determine the bacterial composition in crude oil-contaminated soil from Tabasco and Tamaulipas states, Mexico. The structure and diversity of bacterial communities in the contaminated soil samples were evaluated. It was found that the most abundant phylum is proteobacteria, and some genera showed higher abundance in alkaline or acidic soil.

Summary: Microbial research in petroleum production focuses on MIC control and MEOR, but biofilms on vertical wellbores have received little attention. Study found distinct microbial communities between biofilms and water phase, with richness and diversity decreasing and bacteria-archaea ratio shifting with depth. The geothermal gradient, depleted oxygen, and turbulence were identified as factors influencing community variations.

Summary: This study investigated the microbial communities related to the C-N-S cycle in petroleum reservoirs under different pH conditions using 16S rRNA gene data. The results revealed that pH was a crucial factor influencing the microbial communities, with the lowest diversity observed in acidic conditions. The study also identified a significant number of functional genera which were influenced by pH.

Summary: This study utilized aerobic granular sludge technology to remove ammonium from landfill leachate, analyzing the stability of microbial community structures using PCR-DGGE technology. It was found that high nitrogen loading rates hindered ammonium removal, while low loading rates achieved satisfactory results, indicating the importance of stable wastewater treatment bioreactors in maintaining microbial community stability.

Summary: This study analyzed sediment samples from the non-volcanic Tatta Pani hot springs in Azad Kashmir using both culture-dependent and culture-independent techniques. The results showed high microbial diversity in the enriched sediment samples but adverse changes in the composition of relatively dominant bacteria. Metagenomic analyses are recommended for further study of hot spring microbiota diversity and functionality.
