Safety assessment of L. plantarum strains. Bioamine production was tested using seven different amino acids with a Lactobacillus brevis strain from our collection as positive control. Hemolytic activity was tested using 5% sheep blood supplied Columbia agar. Mucin degradation activity was tested using 3% mucin (from porcine stomach) supplemented medium. For hemolytic activity and mucin degradation activity a Bacillus isolate from a human faeces was used as positive control. L. rhamnosus GG was used as the probiotic positive control
