| Abstract: | Eight bacterial dextrans from NRRL strainsLeuconostoc mesenteroides B-742, B-1299, B-1355, B-1399, and B-1402, and from Streptobacterium dextranicum B-1254 were examined by methylation structural analysis. Methyl ethers of d-glucose that were present in hydrolyzates of permethylated dextrans were analyzed by combined g.l.c.?m.s. as the peracetylated aldononitriles. The various dextrans differed significantly in frequency and type of chain branching. |
