Discussion
Lactic acid bacteria are represented among the members
of the normal microflora and inhabit the digestive
tract of many animal species including human beings,
numerous species of lactic acid bacteria can be detected
in the digestive tract but their prevalence and distribution
varies according to the animal species with which
they are associated14,13 isolated lactic acid bacteria with
probiotics potentials from fermented Nigerian dairy
foods, raw cow milk, whey and intestine of cows. In
this study, lactic acid bacteria were isolated from cow
faeces.
The isolated LAB were identified presumptively based
on phenotypic properties and more accurately by molecular
method. Although for identification of LAB,
phenotypic methods have been most commonly15.
More recently, genetic techniques, such as 16S rDNA
sequencing have been developed which allows a more
consistent and accurate identification of individual
strains16. The identification of the isolated lactic acid
bacteria in this study was done by the sequencing of the
16S rRNA genes of the isolates.
