Abstract excerpt
A nonpolar mutation was made in the oac2 gene of Azorhizobium caulinodans. oac2 is an ortholog of the Salmonella typhimurium rfbD gene that encodes a dTDP-L-rhamnose synthase. The knockout of oac2 changed the lipopolysaccharide (LPS) pattern and affected the extracellular polysaccharide production but had no effect on bacterial hydrophobicity. Upon hot phenol extraction, the wild-type LPS partitioned in the...
