“…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.

“…D. siamensis, and epiphytic yeast species such as Hannaella siamensis, H. phetchabunensis, H. pagnoccae, Nakazawaea siamensis, Pseudozyma vetiver and Wickerhamomyces siamensis (Chamnanpa et al, 2013;Kaewwichian et al, 2013a, 20142015;Landell et al, 2014). Some species were described based on the strains isolated from the phylloplane and inner tissue of plant leaves such as O. tropicalis, Papiliotrema siamense and Wickerhamomyces siamensis (Surussawadee et al, 2014;Khunnamwong et al, 2014Khunnamwong et al, , 2015a.…”

Strain DMKU-CE23 T representing a novel yeast species was isolated from tissue of a corn leaf (Zea may L.) collected in Thailand. A phylogenetic analysis based on the combined sequences of the internal transcribed spacer (ITS) region and the D1/D2 region of the LSU rRNA gene indicated that strain DMKU-CE23 T belongs to the Yamadazyma clade and is clearly distinct from other related species. It therefore represents a novel species of the genus Yamadazyma although the formation of ascospores was not observed. The strain of novel species was most closely related to the type strain of Yamadazyma epiphylla but with 5.1 % nucleotide substitutions in the ITS region and 3.7 % nucleotide substitutions in the D1/D2 region of the LSU rRNA gene. The name Yamadazyma endophytica f.a., sp. nov. is proposed. The type strain is DMKU-CE23 T (=CBS 14163 T =TBRC 5174 T ).

“…Hannaella and Gibberella spp were also overrepresented in OSCC tissues. These are typically found on plants as commensals and pathogens, respectively [34,35]. Therefore, they probably represent contaminants of the OSCC rather than members of the oral mycobiome community, especially that they were found in only one control sample.…”
