Human milk is a source of various lactic acid bacteria
with the potential of probiotics. The aim of this study was to screen in vitro
some probiotic properties of Lactobacillus
gasseri MA-1 originated from human milk. The strain showed γ-hemolytic
activity (no hemolytic activity) and susceptibility to Chloramphenicol, Cloxacillin
and Penicillin G antibiotics. MA-1 with safety properties also exhibited a good
tolerance to pH 2 and 0.3% bile conditions. L. gasseri MA-1 showed high ability of
auto-aggregation (97%). The
co-aggregation activities the strain with five human (Listeria monocytogenes ATCC 7644, Escherichia coli ATCC 35218, Salmonella enteritidis
ATCC 13076, Escherichia coli O157:H7 and Salmonella enteritidis RSKK 171) and two fish (Streptococcus
agalactiae and Vibrio alginolyticus) originated bacteria varied from 45% to 57%. The results indicated that, L. gasseri MA-1 strain could be a
promising candidate for probiotic products.
