| characterization of a polysaccharide component of lipopolysaccharide from pseudomonas aeruginosa iid 1008 (atcc 27584) as d-rhamnan. | structural studies were carried out on a rhamnose-rich polysaccharide isolated from the o-polysaccharide fraction of lipopolysaccharide in pseudomonas aeruginosa iid 1008 (atcc 27584) after destruction of the major o-specific chain by alkaline treatment. the isolated polysaccharide contained rhamnose, 3-o-methyl-6-deoxyhexose, glucose, xylose, alanine, galactosamine and phosphorus in a molar ratio of 67:6.9:4.3:2.1:1.1:1.0:4.1. data from analysis involving smith degradation, methylation, 1h-nmr ... | 1987 | 3113949 |
| structure of the sidechain of lipopolysaccharide from pseudomonas syringae pv. morsprunorum c28. | the sidechain of the lipopolysaccharide from the phytopathogen pseudomonas syringae pv. morsprunorum c28 was shown to be composed of d-rhamnose. using 1h and 13c-nmr spectroscopy, methylation analysis, smith degradation and optical rotation data, the repeat unit was found to have the structure: ----3)-d-rhap-(alpha 1----3)-d-rhap-(alpha 1----2)-d-rhap-(alpha 1---- and a degree of polymerization of approximately 70. attention is drawn to the possible prevalence of d-6-deoxyhexoses in the lipopoly ... | 1985 | 3996404 |
| effect on lipopolysaccharide structure of aeration during growth of a plum isolate of pseudomonas syringae pv. morsprunorum. | the composition of lipopolysaccharide (lps) extracted with aqueous phenol from a virulent english plum isolate of pseudomonas syringae pv. morsprunorum varied according to the partial pressure of oxygen (po2) in the culture medium at the time of harvest. when po2 was low, the organism grew slowly and produced smooth lps bearing rhamnan sidechains. as po2 was raised, the rate of growth increased and smooth lps was replaced by a rough species deficient in rhamnose, which co-extracted with a d-gluc ... | 1994 | 8075800 |
| characterization of pseudomonas pathovars isolated from rosaceous fruit trees in east algeria. | a survey of bacterial diseases due to pseudomonas on rosaceous fruit trees was conducted. in forty two orchards located in the constantine region ( east algeria). pseudomonas isolates were identified on the bases of their cultural and biochemical characteristics . a total of fifty nine phytopathogenic bacteria were isolated from diseased pome and stone fruit trees. thirty one strains comparable to pseudomonas syringae pv. syringae were isolated from cherry (prunus avium l.), plum (p. domestica l ... | 2004 | 15756824 |
