abstract= A xanthan-degrading bacterium, strain AS7T, was isolated from soil and its taxonomic position was determined using a polyphasic approach. Strain AS7T was a Gram-stain-variable, spore-forming, motile, aerobic, rod-shaped bacterium. Phylogenetic analysis based on 16S rRNA gene sequence analysis revealed that strain AS7T belongs to the genus Paenibacillus , sharing the highest level of sequence similarity with Paenibacillus phyllosphaerae PALXIL04T (98.0 %). The cell-wall peptidoglycan contained meso-diaminopimelic acid. MK-7 was the dominant isoprenoid quinone and the major fatty acid was anteiso-C15 : 0. Polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and two unknown phospholipids. These chemotaxonomic characteristics were consistent with the isolate belonging to the genus Paenibacillus . The G+C content of the genomic DNA was 51.0 mol% and the DNA–DNA hybridization value between strain AS7T and P. phyllosphaerae PALXIL04T was only 14.4±2.5 %. On the basis of phylogenetic analyses, phenotypic and chemotaxonomic characteristics, and DNA–DNA relatedness value, strain AS7T represents a novel species of the genus Paenibacillus , for which the name Paenibacillus xanthanilyticus sp. nov. is proposed. The type strain is AS7T (=IBRC M 10987T=LMG 29451T).,
