Interspecies Chemical Signaling in a Methane-Oxidizing Bacterial Community.

ABSTRACT: Multiple species of bacteria oxidize methane in the environment after it is produced by anaerobic ecosystems. These organisms provide reduced carbon substrates for species that cannot oxidize methane themselves, thereby serving a key role in these niches while also sequestering this potent greenhouse gas before it enters the atmosphere. Deciphering the molecular details of how methane-oxidizing bacteria interact in the environment enables us to understand an important aspect that shapes the structures and functions of these communities. Here we show that many members of the Methylomonas genus possess a LuxR-type acyl-homoserine lactone (acyl-HSL) receptor/transcription factor that is highly homologous to MbaR from the quorum-sensing (QS) system of Methylobacter tundripaludum,
