Fermentative Utilization of Fruit Peel Waste for Lactic Acid Production by Lactobacillus plantarum

Mridul Umesh, Dr. K. Preethi

Abstract :

The high production cost involved in the chemical synthesis of lactic acid (LA) along with its increased demand calls for attempts to produce LA efficiently from inexpensive raw materials. The main focus of this research work was to carry out the fermentative production of LA from various fruit peel waste (mango, orange, banana and pineapple) as substrates by employing Lactoctobacillus plantarum as the starter culture. The optimal conditions, in terms of pH, temperature and salt concentration, for lactic acid production were determined. The technological properties such as acidification activity, exopolysaccharide (EPS) production, enzymatic activities and carbohydrate fermentation pattern were studied following standard procedures. The highest lactic acid production was obtained from mango peels (10.08 g/L) , whereas the other substrates viz. orange peels, banana peels and pineapple peels produced 5.74 g/L, 4.68 g/L and 4.68 g/L of lactic acid respectively..
