[SEROLOGICAL PROPERTIES AND BIOLOGICAL ACTIVITY OF PANTOEA AGGLOMERANS LIPOPOLYSACCHARIDES].

The serological and phytotoxic properties of lipopolysaccharide (LPS) of plant pathogens--Pantoea agglomerans were studied. It is known that the thin variations in the structure of the O-specific polysaccharides determining serological specificity of gram- negative bacteria and used as a molecular basis of serological classification schemes. For P.

[Monosaccharide composition of Ralstonia solanacearum lipopolysaccharides].

Results of monosaccharide analysis of Ralstonia solanacearum lipopolysaccharides of the strains of different geographical origin are shown. Such monosaccharides as glucose, rhamnose and glucosamine prevail. Following the results of analysis, strains with supposedly truncated O-polysaccharide are revealed.

[Serological characteristic of lipopolysaccharides of Ralstonia solanacearum].

By immunochemical investigations of eight strains of Ralstonia solanacearum six strains were attributed to four serogroups. Two of them are formed by pairs of R. solanacearum strains 4 and 526; 758 and 7954; two others are represented by single strains--TX1 Ta TS3, correspondingly.

[Characteristic of extracellular lectin in Bacillus subtilis IMV B-7014].

The monosaccharide and fatty acid composition of water and organic phase of lectin was studied. It was established that extracellular lectin contains 15.0% of protein, 4.

[Characterization of Budvicia aquatica lipopolysaccharides].

For the first time lipopolysaccharides (LPS) of 6 Budvicia aquatica strains--representatives of new Enterobacteriaceae species have been isolated. It was shown that the yield of LPS ranged from 0.9 to 7.
