Enzyme production from different fruit and vegetable waste using lactic acid fermentation

Laboratory experiment conducted with the objective of utilizing fruit and vegetable wastes and by-products viz., mango stone, citrus and mixed fruit peels, mosambi peel, banana pseudo-stem cuttings and cauliflower leaves, left over in the open in the fruit and vegetable mandies and processing industries or thrown in rivers for enzyme production showed highest pectinase, cellulose and amylase activity of 0.7605, 021465 and 0.3174 U μmol ml^-1 min^-1 in mosambi peel on 7^th day of Laetobacillus plantarum inculation and 05289 & 0.5218, 0.4543 & 0.4314 and 0.4424 & 0.3626 U m^-1 min^-1 in the mango waste after 13 and 28 days of L. plantarum inoculation, respectively. The Lactobacillus counts were highest (>10⁸) in animal feed from mixed fruit pomace and mango stone waste till 13 days of incubation.
