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 ?-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.eninfo:eu-repo/semantics/openAccessHuman Breast MilkTolerance to Gastrointestinal ConditionAuto-aggregationCo-aggregationArticle9221121810.18036/estubtdc.635397
