Abstract:
... Aims: A novel ferulic acid esterase gene from rumen fungus Anaeromyces mucronatus was cloned, heteroexpressed in Escherichia coli and characterized. Methods and Results: A total of 30 clones exhibiting activity on α-naphthyl acetate (α-NA) were isolated from an A. mucronatus YE505 cDNA library. Sequence analysis revealed that these clones represented two esterase-coding sequences. The gene, fae1A, ...

dairy cows; Ruminococcus flavefaciens; probiotics; feed concentrates; forage; cow feeding; rumen fermentation; cellulolytic microorganisms; digestibility; digestive system diseases; strains; microbial ecology; feed supplements; hay
Abstract:
... Many studies have introduced exogenous bacterial strains into the rumen in an attempt to improve fermentation processes or counteract ruminal digestive disorders. Some attempts have been successful in the establishment of the new strain although others have failed. To a large extent, particular conditions necessary to the establishment of a new strain are not yet fully understood. In the present s ...

Abstract:
... Aims: To develop a real-time Taq nuclease assay (TNA) to enable the in vivo enumeration of Megasphaera elsdenii. Methods and Results: Megasphaera elsdenii YE34 was phenotypically characteristic of the species and had 16S rDNA sequence similarity of 98% to previously described isolates. Calibration of the number of cells of M. elsdenii against the cycle threshold of fluorescent dye release gave a s ...

Streptococcus bovis; ribosomal DNA; cattle; phylogeny; bacteriocins; amino acid sequences; genes; nucleotide sequences; molecular weight; rumen bacteria; antibacterial properties
Abstract:
... Streptococci obtained from rumen sources were tested for the production of antibacterial compounds using a deferred-antagonism plating assay. Of 35 isolates tested, 7 were identified that inhibited the growth of other streptococci. None of the inhibitory activity was due to bacteriophage. Three isolates, LRC0253, LRC0255, and LRC0476, were selected for further characterization. Analysis of 16S rib ...

Abstract:
... Bacterial populations in the ileum of broiler chickens were analyzed by molecular analysis of 16S rRNA genes and compared to those in the cecum. Bacteria found in the ileal mucosa were mainly Gram-positive with low G+C content. There were 15 molecular species among 51 cloned sequences. More than 70% of the cloned sequences were related to lactobacilli and Enterococcus cecorum. Two sequences had 95 ...
