A biopolymer bacterial cellulose is obtained by Acetobacter species and this biopolymer has unique properties because of that it is considered better than plant-based polymers. In the present investigation attempt has made for low-cost media preparation for Acetobacter xylinum NCIM 2526 growth and bacterial cellulose production. Carbohydrate rich fraction was extracted from the soybean industry waste products (Tofu whey, soymilk okara and deffated soy flour) and this fraction was used for the replacement of sugar in the standard medium (Hestrin schramn) composition. Acetobacter xylinum (NCIM 2526) was cultured in the developed medium and a process is was developed for the maximum yield of bacterial cellulose. The design of the study optimised three conditions: inoculum level 8.47%, incubation temperature 28.85°C and soluble carbohydrate rich fraction 90% (conc.) of soybean by products in dilute form. Yield of bacterial cellulose was 4.66gm/ 100ml of medium which was more than the predicted value 4.55gm/ 100ml of RSM. Finally, it is concluded that the process developed for the production of edible bacterial cellulose increases with use of particular carbon sources in some media and selection of medium and growth conditions greatly affect the yield of edible bacterial cellulose.
