Improved Production of Rhamnolipids by a Pseudomonas aeruginosa Mutant
A Pseudomonas aeruginosa mutant derived by random mutagenesis with N-methyl-N¢-nitro-N-nitrosoguanidine, producing high levels of the rhamnolipid biosurfactants was selected on Siegmund-Wagner (SW) plates. The mutant designated P. aeruginosa PTCC1637 produces rhamnolipids at concentrations 10 time more than parent strain. NMR analysis and surface tension measurement showed that the biosurfactan...
متن کاملPregnanes and pregnane glycosides from Hoya carnosa.
Eleven pregnanes were isolated from the hydrolysate of the CHCl3 extract fractionated from the caules of Hoya carnosa. Among these, six pregnanes, including 19-acetoxydigipurpurogenin II, were new, and their structures were elucidated. The structures of twenty new pregnane tetraosides and pentaosides, named hoyacarnosides A-T, besides three known ones from the CHCl3 extract, were determined.
متن کاملSquamous metaplasia of the middle ear epithelium.
This study deals with the expression of cytokeratins (Cks) in squamous cell metaplastic lesions in rat and human middle ear. In rats, squamous metaplastic lesions could be induced during chronic otitis media. The histological features of these lesions were similar to those observed in the human middle ear. Immunohistochemistry revealed that squamous cell metaplasia in both rat and human middle ...
متن کاملAdherence of Pseudomonas aeruginosa to tracheal epithelium.
Adherence of mucoid and nonmucoid strains of Pseudomonas aeruginosa to tracheal epithelium was studied with a perfused-trachea model. The species specificity of adherence was studied by infecting tracheas from hamsters, guinea pigs, or mice. Perfused tracheas from hamsters were infected with strains of P. aeruginosa in the presence of various sugars, lectins, cations, or charged polymers. Adher...
