Genomic and proteomic characterization of a newly isolated <i>Paenarthrobacter ilicis</i> strain and its plasmid-mediated xanthan degradation.

ABSTRACT: Environmental soil samples enriched with xanthan gum led to the discovery and isolation of a novel strain of motile Paenarthrobacter ilicis in Bielefeld, Germany, which possesses a previously uncharacterized xanthan utilization gene region on its sole plasmid. This bacterium is the first member of the Paenarthrobacter genus to feature the ability to degrade xanthan. Growth experiments elucidated the optimal growth conditions with regard to pH (7.0) and temperature (28°C-30°C). The genome of Paenarthrobacter ilicis strain 6C consists of two replicons, namely a chromosome with 4,049,144 nucleotides (62.8% GC content) and a plasmid of 147,742 base pairs (61.8% GC content). This novel Paenarthrobacter ilicis strain carries 3,806 predicted coding regions, approximate
