Abstract

The capsular polysaccharide of Acetobacter methanolicus MB 129 consists of D-Glc, D-Gal, L-Rha, and L-glyceric acid in the molar ratios 1:1:1:0.3. Periodate oxidation, methylation analysis, solvolysis with HF, and detailed 1H and 13C NMR analysis resulted in the structure of the repeating unit shown below. [formula: see text] Bacteriophage Acm7-associated end-alpha-L-rhamnopyranoside hydrolase depolymerizes the CPS even in the presence of the O-acyl group, to give the respective hexa-, nona-, and dodeca-saccharides.

Abstract

Acetobacter methanolicus MB 70 was shown to be related to the type strain of this species MB 58/4 (IMET 10945) having the same galactan-->2)-beta-D-Gal f-(1-->3)-beta-D-Gal p-(1-->as the capsular polysaccharide (CPS) and the O-side-chain of the lipopolysaccharide (LPS). Additionally, a glucan built up of the disaccharide repeating unit-->6)-alpha-D-Glc p-(1-->2)-alpha-D-Glc p-(1-->was identified in strain MB 70. In the CPS, the polymers were present in the ratio approximately 1:1, whereas the glucan preponderated in the LPS. Bacteriophage Acm6 specific to A. methanolicus MB 70 hydrolysed selectively the glucan component of both CPS and LPS. Structural elucidation of the resulting oligosaccharides led to the identification of the phage-associated depolymerase as an endo-alpha-(1-->6)-D-glucopyranoside hydrolase.
