NEUTRAL SUGARS IN LIPOPOLYSACCHARIDES OF RHIZOBIUM TRIFOLII AND ITS NON-NODULATING MUTANT

The nodulating Rhizobium trifola strain 24 and its non-nodulating mutant 24 nod⁻³ have been examined. The exopolysaccharides of both cultures studied contained mannose, galactose and glucose at similar molar ratios. On the other hand some quantitative differences have been found between the lipopoly...

Description
Summary:The nodulating Rhizobium trifola strain 24 and its non-nodulating mutant 24 nod⁻³ have been examined. The exopolysaccharides of both cultures studied contained mannose, galactose and glucose at similar molar ratios. On the other hand some quantitative differences have been found between the lipopolysaccharides in respect of the composition of neutral sugars. Glucose and rhamnose were the main constituents of the nodulating strain 24, whereas rhamnose and galactose in non-nodulating mutant 24 nod⁻³ deprived of the plasmid pWZ2.
