Debaryomyces hansenii (Candida famata), a rare human fungal pathogen often misidentified as Pichia guilliermondii (Candida guilliermondii).
Debaryomyces hansenii is a hemiascomycetous yeast commonly found in natural substrates and in various types of cheese. Pichia guilliermondii is widely distributed in nature and is a common constituent of the normal human microflora. Both species have been described in human infections but are extremely difficult to differentiate phenotypically. Thus, frequent errors in identification occur. The...
متن کاملReducing oxidative stress in sweet cherry fruit by Pichia membranaefaciens: a possible mode of action against Penicillium expansum.
AIMS To investigate the effect of antagonistic yeast Pichia membranaefaciens on alleviating oxidative stress caused by Penicillium expansum in sweet cherry fruit. METHODS AND RESULTS At two maturity stages of sweet cherry fruit, P. membranaefaciens restrained blue mold rot caused by Pe. expansum. There was not any decay in yeast-treated fruit even at 5 days after inoculation. Carbonylated pro...

در این تحقیق تغییرات فعالیت آنزیم پراکسیداز و نیز ترکیبات فنلی در میوه سیب، پس از تیمار با مخمرpichia guilliermondii a6 و سیلیکون (si) و مایه زنی با قارچ عامل بیماری کپک آبی penicillium expansum f1 بررسی شد. نمونه برداری در روزهای صفر، دوم، چهارم، ششم و هشتم پس از مایه زنی قارچ عامل بیماری انجام گرفت. نتایج این آزمایش نشان داد که فعالیت آنزیم پراکسیداز در طی روز های نمونه برداری افزایش یافته و ...
متن کاملThe Ability of the Antagonist Yeast Pichia Guilliermondii Strain Z1 to Suppress Green Mould Infection in Citrus Fruit
In previous studies it was shown that Pichia guilliermondii strain Z1, isolated from healthy Moroccan citrus Valencia-Late oranges, was effective against Penicillium italicum. Here the effectiveness of strain Z1 was assessed against Penicillium digitatum, the causal agent of green mould, under different temperature (5-25°C) and relative humidity (RH) (45-100%) regimes for its reliable and large...
متن کاملResidual Activity of Fludioxonil and Pyrimethanil Against Penicillium expansum on Apple Fruit
At harvest, apple fruit are placed into wooden or plastic bins (approximately 400 kg of fruit per bin), which are then transported to storage and packing facilities. Prior to storage, fruit may be drenched with a fungicide to control postharvest diseases (10). Fruit are stored in the bins in either regular atmosphere (RA) or controlled atmosphere (CA) (1 to 2% O2 and 0.5% CO2) at –1 to 3°C (9)....
