Transcriptional and functional analysis of oxalyl-coenzyme A (CoA) decarboxylase and formyl-CoA transferase genes from Lactobacillus acidophilus.
Oxalic acid is found in dietary sources (such as coffee, tea, and chocolate) or is produced by the intestinal microflora from metabolic precursors, like ascorbic acid. In the human intestine, oxalate may combine with calcium, sodium, magnesium, or potassium to form less soluble salts, which can cause pathological disorders such as hyperoxaluria, urolithiasis, and renal failure in humans. In thi...
متن کاملOxalate consumption by lactobacilli: evaluation of oxalyl-CoA decarboxylase and formyl-CoA transferase activity in Lactobacillus acidophilus.
AIMS This study was undertaken to evaluate the oxalate-degrading activity in several Lactobacillus species widely used in probiotic dairy and pharmaceutical preparations. Functional characterization of oxalyl-CoA decarboxylase and formyl-CoA transferase in Lactobacillus acidophilus was performed in order to assess the possible contribution of Lactobacillus in regulating the intestinal oxalate h...
متن کاملPolyphasic taxonomic analysis of Bifidobacterium animalis and Bifidobacterium lactis reveals relatedness at the subspecies level: reclassification of Bifidobacterium animalis as Bifidobacterium animalis subsp. animalis subsp. nov. and Bifidobacterium lactis as Bifidobacterium animalis subsp. lactis subsp. nov.
The taxonomic standing of Bifidobacterium lactis and Bifidobacterium animalis was investigated using a polyphasic approach. Sixteen representatives of both taxa were found to be phenotypically similar and shared more than 70% DNA-DNA relatedness (76-100%), which reinforces the conclusions of previous studies in which B. lactis and B. animalis were considered to be one single species. However, t...
