Cell-cell communication, or quorum sensing, is a widespread phenomenon in bacteria that
is used to coordinate gene expression among local populations. Its use by bacterial …

Streptococcus pyogenes (Group A Streptococcus, GAS) is an important human commensal
that occasionally causes localized infections and less frequently causes severe invasive …

A nascent cellulosic ethanol industry is struggling to become cost-competitive against corn
ethanol and gasoline. Millions of dollars are spent on nitrogen supplements to make up for …

Microbial interactions, including mutualistic nutrient exchange (cross-feeding), underpin the
flow of energy and materials in all ecosystems. Metabolic exchanges are difficult to assess …

Quorum sensing (QS) regulates diverse and coordinated behaviors in bacteria, including the
production of virulence factors, biofilm formation, sporulation, and competence development…

The ecological significance of light perception in nonphotosynthetic bacteria remains largely
elusive. In terrestrial environments, diurnal oscillations in light are often temporally coupled …

Bacteria predominantly exist as members of surfaced-attached communities known as
biofilms. Many bacterial species initiate biofilms and adhere to each other using cell surface …

Recent studies have established the fact that multiple members of the Rgg family of
transcriptional regulators serve as key components of quorum sensing (QS) pathways that utilize …

Nutrient cross‐feeding can stabilize microbial mutualisms, including those important for
carbon cycling in nutrient‐limited anaerobic environments. It remains poorly understood how …

Microbial interactions abound in natural ecosystems and shape community structure and
function. Substantial attention has been given to cataloging mechanisms by which microbes …
