"Formulation of Cost Effective Alternative Bacterial Culture Media Using Fruit and Vegetables Waste"

Vegetable stalks and fruit peels are generally used for composting or merely disposed off as waste. Considering their nutritional values, these kitchen wastes can be utilized for production of alternative cultivation media. Cost of conventional culture media is very high. Use of these alternatives would reduce the cost drastically. The present study is aimed at replacing the nutrient source by various locally available cheap materials, such as vegetables and fruits waste, that contains considerable amount of protein and starch. These raw materials are cheap and easily available in local shops and vegetable markets and also as kitchen wastes. They were selected as a natural nutrient source to prepare the alternative culture media. Growth of bacteria and pigment production efficiency was analyzed using nine formulations. The results showed that drumstick formulations having seed and peel extract, formulations B and D supported growth of E.coli, Serratia sp., Pseudomonas sp.
