Researchers investigated how anthropogenic land uses (agricultural and urbanized) versus natural land uses shape denitrification-related microbial communities in the Weihe and Hanjiang Rivers in China's Qinling Mountains using deep 16S rRNA gene sequencing of water and sediment samples. Results revealed that land-use type significantly alters the composition and function of nitrogen-cycling microbial communities in freshwater river ecosystems.
Microplastics drive microbial assembly, their interactions, and metagenomic functions in two soils with distinct pH and heavy metal availability
Researchers investigated how microplastics affect soil microbial communities and their functions in two different soil types, one acidic and one neutral. They found that microplastics altered bacterial and fungal community composition and disrupted genes involved in carbon cycling, nitrogen metabolism, and pollutant degradation, with effects varying between the two soil types. The study reveals that soil characteristics like pH and existing heavy metal contamination play a significant role in determining how microplastics impact underground ecosystems.
