Explanation
Leuconostoc mesenteroides NRRL B-512F (and B-512(F)) is the primary industrial organism for dextran production. Dextran is a branched polysaccharide:-1,6-linked glucan backbone with-1,2,-1,3, and-1,4 branch points. Produced by the enzyme dextransucrase from sucrose:sucrosedextranfructose. Industrial applications: Sephadex® gel filtration media (cross-linked dextran); clinical plasma volume expanders (Dextran 40, Dextran 70); drug delivery carriers; food thickeners. Molecular weight can be controlled by reaction conditions. Streptomyces olivaceus produces erythromycin; Bacillus thuringiensis produces Bt toxin; Bacillus polymyxa produces polymyxin antibiotics.
