Anaerobic gut fungi can grow at redox potential values higher than that encountered in their natural habitats.

One-sentence summary: This study demonstrates that interactions among larvae of two Culex mosquitoes strongly impact the composition of bacteria in container aquatic habitats and mosquito bodies.

Our study unveils the community impact on the conjugation efficiency of uropathogenic E. coli isolates, with Gram-positive species, particularly enterococci, enhancing the conjugation efficiency.

Yarrowia lipolytica, known for its metabolic flexibility, forms various products from diverse carbon sources and transitions adeptly between planktonic and biofilm growth. This study examines its biofilm metabolic activities, suggesting potential for continuous bioprocessing.

Assessment on the feasibility of a novel, magnetic bead-based extraction of viruses from wastewater for quantitative (PCR-based) and qualitative (sequencing-based) analyses.
