摘要: In the present work Lactobacillus delbrueckii was used to utilize agro-industrial byproduct (cane molasses) for lactic acid production under submerged fermentation process. Screening of LAB done by Fourier transform infra red spectroscopy (FTIR). Effect different amino acids (DL-Phenylalanine, L-Lysine and DL-Aspartic acid) on process high performance liquid chromatography (HPLC). Central composite rotatable design (CCRD) optimize levels three parameters viz. tween 80, cane molasses concentration during fermentative acid. Under optimum condition enhanced from 55.89 g/L 84.50 g/L. Further, validation showed 81.50 g/L production. Scale up 7.5 L fermentor. Productivity found be 3.40 g/L/h which higher than previous studies with reduced time 24 h 12 h. Further characterization FTIR.
