| Abstract |
The taxonomic position of a novel bacterial strain, Ch06T, isolated from an upflow anaerobic sludge blanket reactor was determined. Strain Ch06T was Gram-negative, aerobic, motile and oxidase- and catalase-positive. A comparative 16S rRNA gene sequence analysis showed a clear affiliation of strain Ch06T to the Alphaproteobacteria and it was most closely related to Zoogloea ramigera ATCC 19623 and Mycoplana dimorpha IAM 13154T (97.9 and 96.3% sequence similarity, respectively). The major respiratory quinone was Q-10 and the predominant fatty acids were C16:0, 3-OH C16:0, C18:0, C19:0 cyclo omega8c and summed feature 7 (C18:1omega7c/omega9t/omega12t, C18:1omega7c/omega9c/omega12t). On the basis of phenotypic, chemotaxonomic and phylogenetic characteristics, the novel isolate was assigned to a new genus, Shinella gen. nov., as Shinella granuli gen. nov., sp. nov. (type strain Ch06T=KCTC 12237T=JCM 13254T). It is proposed that Zoogloea ramigera ATCC 19623 is reclassified into the novel genus Shinella as Shinella zoogloeoides sp. nov. (type strain ATCC 19623T=IAM 12669T=I-16-MT).
