“…Bromeliad tanks contain a highly active microbial community, which can perform rapid decomposition of plant litter through extracellular enzymes and the transformation of nutrients, including nitrogen forms (Humber 2008). Although new yeast species associated with bromeliads of tropical environments have been described (Landell et al 2006(Landell et al , 2009(Landell et al , 2014Araújo et al 2012;Safar et al 2013), little is known about the diversity of yeasts associated with rupicolous tankbromeliads. The enzymatic abilities of these microorganisms may have a significant ecological function for bromeliad life cycles.…”

“…Yeast communities have been associated with a wide variety of plants, including phylloplane and the water tanks of bromeliads (e.g., Hagler et al 1993;Ruivo et al 2005;Landell et al 2006Landell et al , 2009Landell et al , 2010Landell et al , 2014Araújo et al 2012;Safar et al 2013). Bromeliad water tanks in tropical ecosystems are extremely variable aquatic microhabitats, in both space (among bromeliads) and time (environmental conditions can change within hours).…”

The diversity of yeast species collected from the bromeliad tanks of Vriesea minarum, an endangered bromeliad species, and their ability to produce extracellular enzymes were studied. Water samples were collected from 30 tanks of bromeliads living in a rupestrian field site located at Serrada Piedade, Minas Gerais state, Brazil, during both the dry and rainy seasons. Thirty-six species were isolated, representing 22 basidiomycetous and 14 ascomycetous species. Occultifur sp., Cryptococcus podzolicus and Cryptococcus sp. 1 were the prevalent basidiomycetous species. The yeast-like fungus from the order Myriangiales, Candida silvae and Aureobasidium pullulans were the most frequent ascomycetous species. The diversity of the yeast communities obtained between seasons was not significantly different, but the yeast composition per bromeliad was different between seasons. These results suggest that there is significant spatial heterogeneity in the composition of populations of the yeast communities within bromeliad tanks, independent of the season. Among the 352 yeast isolates tested, 282 showed at least one enzymatic activity. Protease activity was the most widely expressed extracellular enzymatic activity, followed by xylanase, amylase, pectinase and cellulase activities. These enzymes may increase the carbon and nitrogen availability for the microbial food web in the bromeliad tank of V. minarum. Sequence analyses revealed the existence of 10 new species, indicating that bromeliad tanks are important sources of new yeasts. The novel species Occultifur brasiliensis, f.a., sp. nov., is proposed to accommodate the most frequently isolated yeast associated with V. minarum. The type strain of O. brasiliensis, f.a., sp. nov. is UFMG-CM-Y375(T) (= CBS 12687(T)). The Mycobank number is MB 809816.

“…The prevalent species in this community were Candida orthopsilosis, Candida pseudointermedia, Cryptococcus heveanensis and Meyerozyma guilliermondii. The phytotelmata of bromeliads are a rich source of novel yeast species, and several species have been described from this microhabitat in Brazil, namely Candida aechmeae (Metschnikowia clade), Candida bromeliacearum (Phaffomyces/Komagataella clade), Candida ubatubensis (Metschnikowia clade), Candida vriseae (Yamadazyma clade), Cryptococcus bromeliarum (Tremellales clade), Kazachstania bromeliacearum, Kazachstania rupicola and Hannaella pagnoccae (Ruivo et al, 2005;Landell et al, 2009Landell et al, , 2010Landell et al, , 2014Araú jo et al, 2012;Safar et al, 2013). The yeast communities probably survive using the water and organic detritus accumulated in phytotelmata.…”

Three strains of a novel yeast species were isolated from water tanks (phytotelmata) of a bromeliad species collected in the state of Tocantins, Brazil. Analysis of sequences for the region spanning the SSU rRNA gene, the internal transcribed spacer, the 5.8S rRNA gene and the D1/D2 domains of the LSU rRNA gene and RNA polymerase II gene showed that these novel yeasts belong to a species that is distinct from all recognized ascomycetous yeast species. Based on the results of gene sequence analyses, a novel species representing a new genus in the Saccharomycetaceae is proposed. The novel species is assigned to the genus Hagleromyces gen. nov. The three isolates of the novel yeast species failed to form sexual spores alone or in mixtures. The name Hagleromyces aurorensis sp. nov. is proposed to accommodate these isolates. The type strain of H. aurorensis sp. nov. is UFMG-CM-Y311T ( = CBS 13264T).

“…Bromeliads are typically abundant plants in the Atlantic Forest and sustain a great diversity of organisms, including yeasts and animals that can act as yeast vectors (Hagler et al, 1993;Araú jo et al, 1998;Landell et al, 2006). Novel yeast species have been isolated from the water tanks and leaves of bromeliads in Brazil, showing the high microbial diversity associated with this substrate (Ruivo et al, 2005;Inácio et al, 2008;Landell et al, 2009).…”

Two novel yeast species, Candida aechmeae sp. nov. and Candida vrieseae sp. nov., were isolated from bromeliads in Itapuã Park, Rio Grande do Sul, Brazil. These species are genetically isolated from all other currently recognized ascomycetous yeasts based on their sequence divergence in the D1/D2 domain of the LSU rRNA gene. C. aechmeae sp. nov. is phylogenetically close to Candida ubatubensis, a species also isolated from bromeliads in Brazil, but the novel species can be differentiated on the basis of differences in the D1/D2 domain and positive results for the assimilation of l-arabinose, raffinose, inulin and citrate. Candida vrieseae sp. nov. is phylogenetically placed in a clade near Candida membranifaciens that is composed of several species associated with insects, but the novel species can be differentiated from them by the D1/D2 and ITS gene sequences, positive results for the assimilation of nitrite and a negative result for the assimilation of ethylamine. The type strain for Candida aechmeae sp. nov. is BI153T (=CBS 10831T=NRRL Y-48456T) and the type strain for C. vrieseae sp. nov. is BI146T (=CBS 10829T=NRRL Y-48461T).
