Abstract

This study was conducted to isolate and identify Lactobacillus species and to find out their
incidence in 35 raw milk samples collected from different areas of Chennai city. A Total of 35
samples of raw milk were used in this study to isolate and identify the lactobaclillus and to find
out the incidence of lactobacillus. MRS agar and LBS agar and streak plate method were found
to be good for isolating and determine lactobacillus from raw milk. Lactobacilli comprised 46.15%
of the total bacterial load among which L.delbrueckii ssp. bulgaricus and L.acidophilus were
27.69 % and 18.46% respectively. All the isolates were confirmed by microscopical, cultural
and biochemical characters

Keywords
