Abstract
As part of an undergraduate microbiology course, a yellow–orange pigmented, Gram-staining negative, rod-shaped, non-motile bacterial strain, designated CTMT, was isolated from a creek in North-central Pennsylvania during the winter of 2006. The 16S rRNA gene sequence of the strain showed ~97 % similarity to that ofChryseobacterium soldanellicolaPSD1-4TandChryseobacterium soliJS6-6T, while the protein-codinggyrBgene sequence of strain CTMTshowed Twas characterized and compared to these and other closely related species of the genusChryseobacterium. Strain CTMTwas similar to other strains of the genusChryseobacteriumin that it contained MK-6 as its major respiratory quinone, produced flexirubin-type pigments, oxidase and catalase, hydrolysed DNA, gelatin and aesculin and contained the fatty acids iso-C15 : 0, iso-C17 : 1ω9c, iso-C17 : 03-OH and summed feature 3 (C16 : 1ω6c, C16 : 1ω7cand/or iso-C15 : 02-OH). Based on the results of this study, strain CTMTrepresents a novel species of the genusChryseobacterium, for which the nameChryseobacterium piperisp. nov. is proposed. The type strain is CTMT( = ATCC BAA-1782T = CCUG 57707T = JCM 15960T = DSM 22249T = KCTC 23267T).
