General stress transcription factor sigmaB and its role in acid tolerance and virulence of Listeria monocytogenes.

abstract：:A bacterium was isolated by elective culture with p-hydroxybenzoate as substrate and nitrate as electron acceptor. It grew either aerobically or anaerobically, by nitrate respiration, on a range of aromatic compounds. The organism was identified as a pseudomonad and was given the trivial name Pseudomonas PN-1.
