Two strains of Rhodotorula and one of Trichosporon precipitated dissolved copper with H(2)S formed by reducing elemental sulfur with glucose. Iron stimulated this activity under certain conditions. In the case of Rhodotorula strain L, iron stimulated copper precipitation aerobically at a copper concentration of 18 but not 180 mug/ml. Anaerobically, the L strain required iron for precipitation o...

Rhodotorula sp. have emerged as opportunistic pathogens, particularly in immunocompromised patients. Knowledge about the susceptibility of Rhodotorula strains to the common antifungal drugs is essential for the treatment of such new infections. The 68 isolates identified as: Rhodotorula mucilaginosa (47 strains; 69%), R. minuta (14; 21%) and R. glutinis (7; 10%) obtained from various sources (f...

One of the major obstacles in the discovery of new antibiotics is the absence of a method for rapid recognition of known compounds. The use of microbes resistant to specific groups of antibiotics as a means of eliminating these compounds was proposed in 1946 by EISMAN, et al.l> and more extensively utilized by STAPLEY2>. In a conventional screening program, based on detection of activity agains...

vanillin is undoubtedly one of the most popular and widely used flavoring agents in the world. natural vanillin is extracted from vanilla beans and is relatively expensive. moreover, the consumer demand for natural vanillin highly exceeds the amount of vanillin extracted by plant sources. this had led to the investigation of alternative routes for its production such as microbial bioconversion....

A study was undertaken to find out the incidence of fungal mastitis in cattle. Out of 200 clinical cases of mastitis, 17 (8.5 %) were found to have been caused by fungi and 9 (4.5%) were identified to be mixed infection of fungi and bacteria. The yeast and yeast like fungi isolated were Candida tropicalis, Candida parapsilosis, Candida guillermondii, Geotrichum candidum, Trichosporon cutaneum, ...
