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...
متن کاملBioactivity 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...
متن کاملTolaasins A--E, five new lipodepsipeptides produced by Pseudomonas tolaasii.
Pseudomonas tolaasii, the causal organism of brown blotch disease of Agaricus bisporus and of the yellowing of Pleurotus ostreatus, was shown to produce in culture tolaasin I (1), tolaasin II (2), and five other minor metabolites, tolaasins A, B, C, D, and E (3-7). These compounds were demonstrated to be important in the development of the disease symptoms. This paper reports on the structural ...
متن کاملAntibacterial performance of MELITININ - BMAP27 hybrid peptide against Staphylococcus aureus and Pseudomonas aeruginosa strains
Abstract Background and purpose: Multiple drug-resistant (MDR) bacterial strains have spread in different parts of hospitals. The aim of this study was to design and synthesize an effective hybrid peptide by combining different parts of two peptides to achieve the highest antibacterial activity and its inhibitory effect against Staphylococcus aureus and Pseudomonas aeruginosa strains. Materia...
متن کاملIn silico study of the ion channel formed by tolaasin I produced by Pseudomonas tolaasii.
A toxin produced by Pseudomonas tolaasii, tolaasin, causes brown blotch disease in mushrooms. Tolaasin forms pores on the cellular membrane and destroys cell structure. Inhibiting the ability of tolaasin to form ion channels may be an effective method to protect against attack by tolaasin. However, it is first necessary to elucidate the three-dimensional structure of the ion channels formed by ...
