Ground bark and heartwood from Alnus rubra and Pseudotsuga menziesii were added to a muddy sediment from a small Oregon stream and incubated in situ. Carbon dioxide and methane production rates were increased by all amendments, the biggest increase being shown with A. rubra wood. Except for sediment amended with A. rubra wood, nitrogen fixation rates from all treatments (including the control) ...

Rhodotorula spp. are capsulated, pigmented, ubiquitous basidiomycetous yeasts causing different superficial and deep-seated opportunistic infections in the debilitated and immunocompromised patient. Earlier considered as saprophytes, fungi belonging to this genus are now considered as emerging pathogens. This is a report of foot bleb infection due to Rhodotorula mucilaginosa in a diabetic patient.

Due to the problems encountered in routine morphological and physiological procedures that are used in yeast identification, DNA-based methods have recently been developed. In the present study, l66 yeast strains were isolated from several apple and citrus cultivars. After analysis by basic morphological methods, the ITS1 and ITS2 regions of the isolates were amplified separately, and the isola...

A fatal case of meningitis due to Rhodotorula mucilaginosa in a 28 year-old HIV-negative male with a history of Hodgkin lymphoma who underwent salvage chemotherapy is presented. Reviewing the literature we identified 13 cases with central nervous system infection due Rhodotorula spp. The disease usually occurs in HIV negative immunosupressed middle-aged males. It takes the form of subacute or c...

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...

Phylogenetic relationships among Chinese species of Morella (Myricaceae) are unresolved. Here, we use restriction site-associated DNA sequencing (RAD-seq) to identify candidate loci that will help in determining phylogenetic relationships among Morella rubra, M. adenophora, M. nana and M. esculenta. Three methods for inferring phylogeny, maximum parsimony (MP), maximum likelihood (ML) and Bayes...

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...
