It was seen that strain 6055 generated three kinds of dextransucrases whose molecular weights were 151 kDa,142kDa and 117kDa,respectively.Among them,the former two ones were found both in supematants and cell wall,while the later was only found in the fermentation liquor.Strain DM 1-2 synthesized two kinds of dextransucrases,and their molecular weights were 183kDa and 142kDa,respectively.The former existed both in cell wall and out of cell,but the later only was located on cell surface.Strain PC 13 produced three kinds of dextransucrases,and their molecular weights were 148kDa, 138kDa and 115kDa,respectively.The former two ones were ectoenzyme while the later was linked to cell.Resembled to strain 6055,strain L4 produced two types of dextransucrases coexisting in supernatants and cell wall with molecular weights of 145 kDa and 136kDa,respectively,but the dextransucrase of 115kDa was only found in free-cells supernatants.
