Wild-type and saccharopine dehydrogenaseless mutant strains of Rhodotorula glutinis grew in minimal medium containing lysine as the sole nitrogen source and simultaneously accumulated, in the culture supernatant, large amounts of a product identified as alpha-aminoadipic-delta-semialdehyde. The saccharopine dehydrogenase and pipecolic acid oxidase levels remained unchanged in wild-type cells gr...

Bacteriol. 83:381-394. 1962.-The structure and manner of nuclear division in Rhodotorula glutinis was studied by electron microscopy of ultrathin sections. Parallel studies with the light microscope, employing conventional staining techniques and phase-co...

1. beta-Ionone vapour has been shown to cause an increase in the more saturated carotenes and a decrease in the less saturated carotenes of Rhodotorula glutinis. Lycopersene (dihydrophytoene) has been proposed as a precursor to phytoene. Attempts were made to isolate lycopersene from beta-ionone-treated cultures of R. glutinis. 2. Large samples of beta-ionone-treated cultures were examined for ...

UNLABELLED This study investigated the possible relationships between exposures to mite allergen and airborne fungi with sick building syndrome (SBS) symptoms for residents living in newly built dwellings. We randomly sampled 5709 newly built dwellings in six prefectures from northern to southern Japan. A total of 1479 residents in 425 households participated in the study by completing question...

Most small genera containing yeast species in the Pucciniomycotina (Basidiomycota, Fungi) are monophyletic, whereas larger genera including Bensingtonia, Rhodosporidium, Rhodotorula, Sporidiobolus and Sporobolomyces are polyphyletic. With the implementation of the "One Fungus = One Name" nomenclatural principle these polyphyletic genera were revised. Nine genera, namely Bannoa, Cystobasidiopsis...

some yeast species play important roles in biological control of some fruits’ post harvest infections. for instant, candida, rhodotorula and pichia species employed in biological control of such post harvest diseases as blue mold (penicillium expansum), and also grey mold (botrytis mali) in apple. species identification of yeasts is some most essential part of the related research activities. d...

1. The incorporation of [2-(14)C]acetate, [2-(14)C]mevalonic acid and [2-(14)C,2-(3)H(2)]-mevalonic acid into torulene and torularhodin by Rhodotorula rubra and Rhodotorula glutinis was studied. 2. A recovery of 14.3% of the label was obtained on decarboxylation of the torularhodin biosynthesized from [2-(14)C]mevalonic acid. 3. An analysis of the (3)H/(14)C ratio in torularhodin gave a value o...

Under intensive aeration (1.3 l/l min) the associated growth of Rhodotorula rubra GED2 and Lactobacillus casei subsp. casei in cheese whey ultrafiltrate (55 g lactose/l) proceeded effectively for both cultures with production of maximum carotenoids (12.4 mg/l culture fluid). For maximum amount of carotenoids synthesized in the cell, the yeast required more intensive aeration than the aeration n...
