Abstract
Effects of undecanoic acid on exocellular lipase, phospholipase A and keratinase activities of wild type undecanoic acid-sensitive (udas) and an undecanoic acid-resistant mutant (udar) of Trichophyton rubrum (derived from the udas strain) were determined. Undecanoic acid inhibited the production of exocellular lipase and keratinase but stimulated the production of exocellular phospholipase A in T. rubrum udas. Undecanoic acid did not affect exocellular lipase production by T. rubrum udar. Lipase production by the udar mutant was lower than that of the udss parent. No exocellular keratinase could be detected in the udar strain which had very low capacity for invasion of keratinized tissue. Die Wirkung von Undecanoidsäure auf die Aktivität von exozellulärer Lipase, Phospholipase und Keratinase eines Pilztypes eines Undecanoidsäure-sensitiven T. rubrum und einer von diesem Stamme selektionierten resistenten Mutante wurden bestimmt. Undecanoidsäure hemmte die Produktion der exozellulären Lipasen und Keratinasen, stimulierte aber die Produktion exozellulärer Phospholipasen in T. rubrum (sensitiver Stamm). In der resistenten Mutante beeinflusste Undecanoidsäure die Produktion von exozellulären Lipasen nicht. Die Produktion der Lipase war im resistenten Stamm niedriger als im sensiblen Pilzstamm. Keine exozelluläre Keratinase wurde in der resistenten Mutante gefunden, die eine geringere Fähigkeit hatte, in keratinisiertes Gewebe einzudringen.This publication has 18 references indexed in Scilit:
