This study aimed to evaluate the effect of various factors on the yield of lactic acid fermentation using sap from sugar palm and Lactobacillus casei. The sugar palm sap after harvesting, pretreatment was added with ammonium sulphate, calcium carbonate and microbial culture at density of 109 cells/ml and let fermented for acid lactic production. The results of the experiments showed that the culture size, amount of added ammonium sulphate and calcium carbonate had significant effect on lactic acid production. The most appropriate parameters determined were culture size of 5%, ammonium sulphate of 3.0 g/l and calcium carbonate of 4.0 g/l. Meanwhile, the optimum period of fermentation was 100 h, which gave the yield of lactic acid production of 22.30 g. Lactobacillus casei was considered to have lower ability to effectively produce lactic acid from sugar palm sap compared to Lactobacillus plantarum

The demand for lactic acid is steadily increasing due to the desire of its bioproduction over chemical synthesis. The associated cost, however, is a significant hurdle. This study reports lactic acid fermentation by Lactobacillus casei ATCC334 from cassava peel. It investigates the effect of unhydrolysed cassava peels, acidic, alkali hydrolysates; fermenting pH; substrate concentration; nitrogen source concentration; duration; and inoculum size. An attempt at a cheaper purification and recovery protocol relative to those currently in use was similarly performed. Acidic hydrolysate yielded 10.53%, unhydrolysed substrate gave 4.80% with alkali hydrolysate yielding 4.75%. The highest LA yield was obtained at pH 6.0, 2.0% v/v inoculum size, 25% w/v substrate concentration, 5% nitrogen source concentration. A post-optimisation combination yielded 18.3% LA suggesting that one-factor-at-a-time may be unsuitable for optimisation studies involving cassava peel and L. casei ATCC334. FTIR spectra of product suggests effective partial purification. Hence, an improvement in the optimization strategy for production is recommended for subsequent study.
