چکیده

The complete structure of the O-specific polysaccharide of the lipopolysaccharide isolated from the cultivated mushrooms pathogen Pseudomonas tolaasii is described. The structural determination, achieved by chemical and spectroscopical analyses, indicates a novel tetrasaccharide repeating unit built up of two units of 2-acetamido-2,6-di-deoxy-glucopyranose (Quinovosamine, QuipNAc) and two units of 2-acetamido-2-deoxy-gulopyranuronamide (GulpNAcAN), one of which is acetylated at C-3 position:

Bioactive and Structural Metabolites of Pseudomonas and Burkholderia Species Causal Agents of Cultivated Mushrooms Diseases1

Pseudomonas tolaasii, P. reactans and Burkholderia gladioli pv. agaricicola, are responsible of diseases on some species of cultivated mushrooms. The main bioactive metabolites produced by both Pseudomonas strains are the lipodepsipeptides (LDPs) tolaasin I and II and the so called White Line Inducing Principle (WLIP), respectively, LDPs which have been extensively studied for their role in the...

Purification of a pore-forming peptide toxin, tolaasin, produced by Pseudomonas tolaasii 6264.

Tolaasin, a pore-forming peptide toxin, is produced by Pseudomonas tolaasii and causes brown blotch disease of the cultivated mushrooms. P. tolaasii 6264 was isolated from the oyster mushroom damaged by the disease in Korean. In order to isolate tolaasin molecules, the supernatant of bacterial culture was harvested at the stationary phase of growth. Tolaasin was prepared by ammonium sulfate pre...

Bioactivity of volatile organic compounds produced by Pseudomonas tolaasii

Pseudomonas tolaasii is the main bacterial pathogen of several mushroom species. In this paper we report that strains of P. tolaasii produce volatile substances inducing in vitro mycelia growth inhibition of Pleurotus ostreatus and P. eryngii, and Agaricus bisporus and P. ostreatus basidiome tissue blocks brown discoloration. P. tolaasii strains produced the volatile ammonia but not hydrogen cy...
