This study investigates how organic nitrogen inputs and associated microbial communities affect Microcystis growth and toxin production, showing that microbial interactions influence nitrogen availability and cyanotoxin levels.

The paper isolates and sequences 21 Microcystis cultures from Lake Erie, revealing genomic diversity and toxin production variability, along with associated bacterial communities.

The paper introduces a semi-automated DNA-SIP pipeline to improve efficiency and reproducibility in microbial community studies, demonstrating its application in analyzing the hyphosphere of arbuscular mycorrhizal fungi.

This study uses qSIP with metagenomics to link microbial activity and physiology to soil moisture in Mediterranean grasslands, finding that precipitation levels influence microbial growth and phage dynamics.

The paper examines how mean annual precipitation affects microbial community growth and soil carbon cycling in three California grasslands, finding that growth rates and community composition vary with precipitation.

The paper develops a hydrogel-based microplate to study bacterial responses to spatial nutrient gradients from algae, showing taxon-specific community development influenced by nutrient availability.
