  • Using different growth medium greatly improves distinction of Butyrivibrio fibrisolvens and Pseudobutyrivibrio xylanivorans strains by the cellular fatty acids and aldehydes profiles = Uporaba različnih gojišč bistveno olajša ločevanje sevov Butyrivibrio fibrisolvens in Pseudobutyrivibrio xylanivorans na osnovi profilov maščobnih kislin in aldehidov

    A total of 11 ruminal strains currently assigned to Butyrivibrio fibrisolvens and Pseudobutyrivibrio xylanivorans were cultivated in two different media, rumen fluid containing M2 and short-chain ... fatty acid (SCFA ) containing M330, and their cellular fatty acid methyl esters (FA ME) and dimethylacetals (DMA) were analyzed using gas chromatography. A comparison of the FA ME/DMA compositions revealed that the difference in SCFA contents in the growth medium induced a pronounced quantitative effect on the cellular branched-chainfatty acid and aldehydes proportions only in the P. xylanivorans strains. This study shows that FA ME/DMA analysis is a powerful chemotaxonomic tool in the group of phenotypically similar rumen butyrivibria especially when the influence of the growth medium is evaluated.
