| diversity of yeasts from puddles in the vicinity of midre lovénbreen glacier, arctic and bioprospecting for enzymes and fatty acids. | a total of 132 yeast strains were characterised from 4 sediment samples collected from small puddles in the vicinity of midre lovénbreen glacier, arctic. based on the d1/d2 domain sequence similarity, the isolates could be categorised into 6 groups. the nearest phylogenetic neighbour of groups i to vi were identified as cryptococcus gastricus, cryptococcus terricolus, rhodotorula muscorum, mrakia psychrophila, mrakia gelida and rhodotorula glacialis, respectively. strains representative of the s ... | 2010 | 19967375 |
| yeast and yeast-like diversity in the southernmost glacier of europe (calderone glacier, apennines, italy). | the present study reports the characterization of psychrophilic yeast and yeast-like diversity in cold habitats (superficial and deep sediments, ice cores and meltwaters) of the calderone glacier (italy), which is the southernmost glacier in europe. after incubation at 4 and 20 degrees c, sediments contained about 10(2)-10(3) cfu of yeasts g(-1). the number of viable yeast cells in ice and meltwaters was several orders of magnitude lower. the concomitant presence of viable bacteria and filamento ... | 2010 | 20402775 |
| cryptococcus ibericus sp. nov., cryptococcus aciditolerans sp. nov. and cryptococcus metallitolerans sp. nov., a new ecoclade of anamorphic basidiomycetous yeast species from an extreme environment associated with acid rock drainage in são domingos pyrite mine, portugal. | in this report, we describe three novel asexual basidiomycetous yeast species, cryptococcus aciditolerans sp. nov. (type strain cbs 10872t=sdy 081t), cryptococcus ibericus sp. nov. (type strain cbs 10871t=sdy 022t) and cryptococcus metallitolerans sp. nov. (type strain cbs 10873t=sdy 190t), which were isolated from acid rock drainage collected at the são domingos mine in southern portugal. phylogenetic analysis of molecular sequence data indicated that the novel species belong to the order filob ... | 2009 | 19620371 |
| rhodotorula himalayensis sp. nov., a novel psychrophilic yeast isolated from roopkund lake of the himalayan mountain ranges, india. | twenty-five psychrophilic yeasts were isolated from the soil of roopkund lake, himalayas, india. two colony morphotypes were identified and representatives of 'morphotype 1' were identified as cryptococcus gastricus. representatives of 'morphotype 2', namely 3at, 4a, 4b and rup4b, showed similar phenotypic properties and are identical with respect to the nucleotide sequence of the its1-5.8s rrna gene-its2 region and d1/d2 domain of the 26s rrna gene. the sequence of d1/d2 domain of 3at shows 97. ... | 2008 | 18305897 |
| green and brown colour effects in tremellaceous yeast fungi on staib agar. | fifty-eight species of basidiomycetous yeast fungi were examined for green and brown colour effects (gce, bce) on staib agar (guizotia abyssinica creatinine agar). in addition to 9% of cryptococcus laurentii strains tested, only cryptococcus podzolicus was gce-positive. out of 14 strains of this species, 13 showed a gce and four showed a bce. all gce-positive strains utilized creatinine and creatine as a source of nitrogen but not of carbon. none of these strains could grow at 37 degrees c. unli ... | 2000 | 10838839 |
