Production of dextran by newly isolated strains of Leuconostoc mesenteroides through batch fermentation, [Yeni ayrıştırılmış Leuconostoc mesenteroid PCSIR-4 ve PCSIR-9 suşlarında dextran üretimi]

Different isolated strains of Leuconostoc mesenteroides produce dextran compared with that of L. mesenteroides NRRL B-512 F. Among nine newly isolated strains, strains PCSIR-4 and PCSIR-9 produced dextran of different quality. Using these two newly isolated strains, the development of dextran coi...
