Modulation of the ComA-dependent quorum response in Bacillus subtilis by multiple Rap proteins and Phr peptides.

abstract：:The nonstarter lactic acid bacterium Lactococcus raffinolactis is prevalent in a wide range of environments, such as the dairy environment, but little is known about this species. Here, we present the draft genome of Lactococcus raffinolactis strain 4877, isolated from a natural mesophilic dairy starter culture. ...
