The use of natural health supplements has become widely accepted as a natural means to promote health for both humans.
The study deals with the use of fruit peels for growth of bacteria, natural health supplements called as Probiotics. Lactobacillus, which is used in food industry for fermentation, preservation and as food additives, in pharmaceutical industry as probiotic and antimicrobial substances. Different fruit peels were tested. Maximum growth was observed in papaya peel extract. Quantitative analysis of papaya peel extract was found to be having sugar concentration of 20.23mg/ml.Various factors affecting growth of Lactobacillus in PPE media were determined and it was found that optimum pH was 7.0,temperature was 370C and the organism was found to survive at 2.0% NaCl and 0.3% MB. On comparing the results of PPE with MRS, the growth was found to be about 1/5th in PPE than in MRS media.
