| phylogenetic placement of dialister pneumosintes (formerly bacteroides pneumosintes) within the sporomusa subbranch of the clostridium subphylum of the gram-positive bacteria. | the nucleotide sequence of the 16s rrna gene of the type strain of dialister pneumosintes was determined. phylogenetic analysis revealed that this species belongs to the sporomusa branch of the clostridium subphylum of the gram-positive bacteria and should therefore be excluded from the family bacteroidaceae. within this branch, which encompasses several other gram-negative taxa, such as acidaminococcus, pectinatus, phascolarcobacterium, quinella, selenomonas, and zymophilus, dialister showed a ... | 1995 | 7537075 |
| proposal of quinella ovalis gen. nov., sp. nov., based on phylogenetic analysis. | quin's oval is a relatively large bacterium often seen in the rumens of sheep fed diets containing some readily fermented carbohydrates. it has not been obtained in axenic cultures, but a number of its features have been determined by various methods, such as studying cell suspensions purified from rumen fluid by differential centrifugation. we obtained similarly purified suspensions from a sheep fed a diet containing a large amount of molasses. nearly complete 16s rrna sequence analysis of thes ... | 1993 | 7684240 |
| changes in the rumen bacterial community in response to sunflower oil and fish oil supplements in the diet of dairy sheep. | rumen microbial biohydrogenation of dietary unsaturated fatty acids has a major effect on the process of developing healthier dairy products. this study aimed to investigate in vivo the effect of diet supplementation with sunflower (so) and fish (fo) oils on the rumen bacterial community in dairy sheep. first, 32 lactating ewes, divided in 8 lots of 4 animals each (2 lots per treatment), were fed a high-concentrate total mixed ration supplemented with 0, 2% so, 1% fo, or 2% so plus 1% fo. after ... | 2010 | 20630243 |
| performance of a sulfidogenic bioreactor and bacterial community shifts under different alkalinity levels. | the performance of a sulfidogenic bioreactor and the response of bacterial populations to influent alkalinity changes were investigated. the bioreactor reached 40% of sulfate removal efficiency (sre) with 0 mg l(-1) of alkalinity, and single-stranded conformation polymorphism profiles showed that some members of bacteroides, dysgonomonas, sporobacter, quinella, and citrobacter became dominant populations. 16s rrna gene library analysis indicated that the actinobacteria group increased from 0% in ... | 2010 | 20688512 |
