SYNTHESIS OF LACTIC ACID WITH CELLS OF LACTOBACILLUS PARACASEI IMMOBILIZED IN CALCIUM ALGINATE GEL

Lactobacillus paracasei cells immobilized in calcium alginate gel granules were used as the biocatalyst for glucose solutions fermentation to lactic acid. It was stated, that this way of immobilization does not reduce fermentation activity of the cells and calcium alginate gel does not make significant diffusive barriers for substrate and the products of cells metabolism. It was also stated that in the solutions with high lactic acid concentrations (over 63 g/l) the granules of calcium alginate gel destruct in less than 24 hours of use.
