PRODUCTION OF LACTIC ACID BY Lactobacillus plantarum IN SEMI SOLID STATE FERMENTATION USING SOME RAW STARCHY MATERIALS.
Lactobacillus plantarum was selected to ferment raw starchy materials of 'rice bran ,wheat bran and potatoes peel" to produce lactic acid and calcium lactate in semi-solid state fermentation.
The noncooked starchy substrates were suspended in diluted solution of sulfuric acid over night not only for the sterilization of the substrate,but also to help the evolution of carbon dioxid upon addition of calcium carbonate( 0.5%) .,followed by inoculation of the bacteria( 1 Ox1 09 CFU/1 Oml).
The selected organism produced lactic acid ranged from 0.49 to 0.75 gIL and the yield of lactate ranged from 6 2 to 78 g IL of substrate.Maximum starch conversion
to lactic acid was obtained after 120 h.at pH 6.5. .
The addition of small amount of glucoamylase to the fermentation mixture . resulted in a significant shortening of the fermentation process by Lactobacillus plantarum cultivated at 37 C,without any other additives.
