摘要:
The capsular polysaccharide (CPS) and the O-side-chain of the lipopolysaccharide (LPS) of Acetobacter methanolicus MB 58/4 (IMET 10945) have been shown to contain the same disaccharide repeating unit, namely, --> 2)-beta-D-Galf-(1 --> 3)-beta-D-Galp-(1 -->. Degradation of the CPS and the LPS with the bacteriophage Acm1 gave fragments built up of 1-5 repeating units: the octasaccharide preponderated. The phage-associated depolymerase proved to be a beta-D-galactofuranoside hydrolase.
