Visualizing and identifying selfish bacteria: a hunting guide

The paper provides a guide to identify and visualize selfish bacteria through methods to detect their unique polysaccharide processing mechanism in complex bacterial communities.

Selfish bacteria are active throughout the water column of the ocean

The paper shows that selfish bacteria are active in deep ocean waters, suggesting that the return on investment for their energy-intensive strategy is sufficient to sustain them in these environments.

A Sea Change in Microbial Enzymes: Heterogeneous latitudinal and depth-related gradients in bulk water and particle-associated enzymatic activities from 30°S to 59°N in the Pacific Ocean

The paper measures hydrolytic enzyme activities in bulk water and particle-associated samples across the Pacific Ocean, revealing heterogeneous latitudinal and depth-related patterns.

Quantifying fluorescent glycan uptake to elucidate strain-level variability in foraging behaviors of rumen bacteria

The paper uses fluorescent glycan uptake and genomic analyses to study strain-level differences in carbohydrate metabolism among rumen bacteria.

Short-term changes in polysaccharide utilization mechanisms of marine bacterioplankton during a spring phytoplankton bloom

The paper tracks changes in polysaccharide utilization modes by heterotrophic bacteria during a spring phytoplankton bloom, showing shifts from selfish uptake to external hydrolysis as the bloom progresses.

Global ecotypes in the ubiquitous marine clade SAR86

The paper identifies five SAR86 gene clusters with distinct geographic distributions and environmental associations, revealing complex biogeography and functional specialization.
