paenibacillus bovis sp. nov., isolated from raw yak (bos grunniens) milk.strain bd3526t, isolated from raw yak milk collected in tibet, china, was studied to determine its taxonomic status. the strain is gram-positive, motile, catalase positive, aerobic or facultatively anaerobic. the dna g+c content of the strain is 47.5 mol% and its peptidoglycan contains meso-diaminopimelic acid. the predominant menaquinone is mk-7. the major cellular fatty acids of the strain are anteiso-c15:0, anteiso-c17:0 and c16:0. for 16s rrna sequence, similarities among strain bd3526t and ...201626769366
characterization of the levan produced by paenibacillus bovis sp. nov bd3526 and its immunological activity.paenibacillus bovis sp. nov bd3526 synthesizes a large amount of exopolysaccharides (epss) (36.25g/l) in a semi-defined chemical medium containing 20% (w/v) sucrose. the epss were extracted from the cultured broth by ethanol precipitation and purified via anion-exchange and gel permeation chromatography. the fourier transform infrared (ft-ir) and nuclear magnetic resonance (nmr) spectra showed that the primary eps fraction (f1) was a linear β (2→6)-linked levan. the peak molecular weight (mp) of ...201627083807
