Abstract: Objective: The aim of this study was to test the ability of Lactobacillus brevis and Lactobacillus plantarum derived from fermented cabbage waste juice to acts as probiotics. Materials and Methods: Tests of probiotic ability included tests of bile salt resistance and pH resistance and tests of sensitive inhibition of Escherichia coli and Salmonella pullorum growth. Results: Lactobacillus brevis and Lactobacillus plantarum derived from fermented cabbage waste juice were able to grow and develop at pH values from 2.5-5.5 and bile salt concentrations of 1-5%. Lactobacillus brevis was able to strongly inhibit Escherichia coli and Salmonella pullorum growth, while Lactobacillus plantarum showed very potent inhibition of Escherichia coli growth and potent inhibition of Salmonella pullorum growth. Conclusion: Lactobacillus brevis and Lactobacillus plantarum derived from fermented cabbage waste juice are suitable for use as poultry probiotics.
