Leuconostoc mesenteroides is a bacterial species sometimes associated with fermentation, under conditions of salinity and low temperatures (such as lactic acid production in fermented sausages). When grown in sucrose solution, it converts the sugar to dextrans having mostly alpha 1,6 linkages, but 1,2, 1,3, and 1,4 linkages are also present.
