Abstract

STUDY of the formation of micro-organisms of polysaccharides from sucrose has been hampered by the absence of a satisfactory technique for the cell-free isolation of the enzyme catalysts concerned1. This obstacle has now been removed. The separation of a dextran-synthesizing enzyme from Leuconostoc mesenteroides has been reported recently by Hehre2. It is the purpose of the present note to report the isolation from Bacillus subtilis and Aerobacter of an enzyme or enzymes which act on sucrose with formation of levan.
