USE OF NOVEL WASTE PRODUCTS IN THE MICROBIAL PRODUCTION OF LACTIC ACID
Original language description
The objective of our project was to design and optimize the process of microbial production of lactic acid using an alternative, inexpensive substrate with the goal to achieve high yield and concentration of lactic acid produced by the strain Lactobacillus casei 198. Firstly, the chicken feather was investigated as a low-cost source of nitrogen. Feather was hydrolysed with sodium hydroxide at a concentration of 2, 5, 10, 15 and 20 % by weight and used as a replacement of all nitrogen sources in MRS medium. Taking the growth of biomass and the final concentration of lactic acid as the main criterions, 20% hydrolysate of chicken feather was chosen for the next experiments, where it was used not only as a source of nitrogen but also as an neutralizing agent. Using this hydrolysate caused minimal dilution of the total volume of the culture medium in the bioreactor. The final concentration of lactic acid in the medium was 48 g l-1.
