Investigation Of Probiotic Potential Of Lactic Acid Bacteria And Its Response To Cold Stress:- Eke, Mercy U
ABSTRACT
This study was aimed at investigation of
probiotic potential of Lactic acid bacteria and its response to cold stress.
Two (2) samples each of ogiri and ugba were purchased from local vendors within
Umuahia metropolis and taken to Microbiology laboratory for the isolation of
lactic acid bacteria, using standard microbiological method. After the
microbial analysis, two species of LAB were isolated as Lactobacillus
bulgaricus and Leuconostroc mesenteriods. The percentage occurance of
Lactobacillus bulgaricus was higher (80%) was higher than Leuconostroc
mesenteriods (20%). The result of the cold stress showed that a decrease in
temperature results in decrease in survival rate of LAB. Antimicrobial activity
of the isolates showed a high sensitivity to some pathogenic bacteria. High
level of sensitivity (20mm) to S. aureus and Puedomonas aeruginosa and 5- I 0mm
of inhibition for £. coli and Salmonella typhi were recorded among the
isolates. The finding of this study therefore calls for high consumption of
fermented food products as it helps ameliorate immunologic diseases such as
allergy, cancer, and ulcerative colitis and also subjection of fermented food
products to cold stress help in its preservation.
