Both strains were immobilized by 4% (w/w) of pectin crude extract from Krung Kha Mao (KKM pectin) leaves, 1.52 mm inner diameters of silicone tube and 5% (v/v) inoculum for immobilization. Efficiency of lactic acid production was compared by immobilized cells ofL. casei subsp, rhamnosus TISTR 108 when KKM pectin, commercial citrus pectin, commercial apple pectin and sodium alginate were used as supporting materials to produce lactic acid 38.50, 38.76, 30.43 and 34.56 g/L, respectively, the productivity of lactic acid has been 0.40, 0.40, 0.36 and 0.36 g/L h, respectively.展开更多
