“…In the leaves and fruits of S. brasiliensis, the dominant species belong to the genera Candida, Aureobasidium, Wickerhamiella, and Rhodotorula. Species of the genera Candida and Rhodotorula are frequently reported in studies on the diversity of yeasts that occur in fruits [19,41,48,[50][51][52] and leaves [35,53,54]. It is only A. humile that has had part of its mycobiota recently studied by our team using samples from another region of the Brazilian Cerrado [19], where Candida easanensis, Debaryomyces fabryi, D. nepalensis, Hanseniaspora meyeri, H. opuntiae, Meyerozyma caribbica and Rhynchogastrema complexa were reported.…”

Background: This work studied the occurrence, density, and diversity of yeast species associated with the leaves and fruits of Sabicea brasiliensis and Anacardium humile. Methods: Fragments of leaves and fruits were subjected to maceration and placed under agitation in peptone water. One hundred µL aliquots of each of the decimal dilutions were plated on YM chloramphenicol agar medium. The different morphotypes were identified through sequence analysis of the 26S rDNA. Results: A total of 83 yeast isolates were recovered from the organs sampled, 40 from fruits and 19 from the leaves of S. brasiliensis, while 14 were recovered from fruits and 10 from the leaves of A. humile. The isolates were identified as belonging to two phyla, six classes, eight orders, and eight families. Most isolates, at 71 (84.3%), belong to Ascomycota, with Saccharomycetes dominant in fruits and Dothideomycetes in leaves. The remaining 12 (15.7%) isolates belong to the phylum Basidiomycota. The most frequent genera were Aureobasidium, Candida, Rhodotorula, and Wickerhamiella. The Wickerhamiella isolates made possible the subsequent description of a new species within this genus. Conclusions: Our data reveal the yeast species that inhabit different Cerrado plant organs and indicate that these hosts can be considered an important habitat for yeast diversity, including new and/or previously unreported species in this biome.

“…Many yeast species were isolated from either plants, plant materials, or plant associated sources including fruits, exudates of plants, peat moss, phylloplane of plants, flowers, decomposed plants, fermented tea leaves (Miang), cacti, bark of trees, and cotton. These species include C. albicans [55] , C. jaroonii [56] , [57] , C. palmioleophila [58] , Lodderomyces elongisporus [59] , Metschnikowia koreensis [57] , [59] – [61] , M. saccharicola [62] , Cyberlindnera fabianii [57] , [59] , Cy. jadinii [63] , Cyberflaneur subsufficiens [64] , Starmera stellimalicola [65] , [66] , C. ethanolica [67] , C. pseudolambica [57] , Pichia manshurica [47] , P. occidentalis [68] , Kluyveromyces marxianus [47] , K. starmeri [69] , C. nonsorbophila [70] , Diutina rugosa [57] , Wickerhamiella martinezcruziae [71] , Papiliotrema ruineniae [72] , Rhodosporidiobolus fluvialis [73] , and Rhodotorula diobovata [74] .…”

<abstract> The diversity of duckweed (<italic>Lemnaceae</italic>) associated yeasts was studied using a culture-dependent method. A total of 252 yeast strains were isolated from 53 duckweed samples out of the 72 samples collected from 16 provinces in Thailand. Yeast identification was conducted based on the D1/D2 region of the large subunit (LSU) rRNA gene sequence analysis. It revealed that 55.2% and 44.8% yeast species were Ascomycota and Basidiomycota duckweed associated yeasts, respectively. Among all, <italic>Papiliotrema laurentii</italic>, a basidiomycetous yeast, was found as the most prevalent species showing a relative of frequency and frequency of occurrence of 21.8% and 25%, respectively. In this study, high diversity index values were shown, indicated by the Shannon-Wiener index (<italic>H′</italic>), Shannon equitability index (<italic>EH</italic>) and Simpson diversity index (<italic>1-D</italic>) values of 3.48, 0.86 and 0.96, respectively. The present results revealed that the yeast community on duckweed had increased species diversity, with evenness among species. Principal coordinate analysis (PCoA) revealed no marked differences in yeast communities among duckweed genera. The species accumulation curve showed that the observed species richness was lower than expected. Investigation of the plant growth promoting traits of the isolated yeast on duckweed revealed that 178 yeast strains produced indole-3-acetic acid (IAA) at levels ranging from 0.08–688.93 mg/L. Moreover, siderophore production and phosphate solubilization were also studied. One hundred and seventy-three yeast strains produced siderophores and exhibited siderophores that showed 0.94–2.55 activity units (AU). One hundred six yeast strains showed phosphate solubilization activity, expressed as solubilization efficiency (SE) units, in the range of 0.32–2.13 SE. This work indicates that duckweed associated yeast is a potential microbial resource that can be used for plant growth promotion. </abstract>

“…Representatives of the genus Rhodosporidiobolus have been isolated from various sources, including cold ecosystems [ 31 , 32 ], apple and pear surfaces [ 33 ], apple pulps [ 34 ], grapes [ 35 ], marine ecosystems associated with invertebrates such as sponges [ 36 ] and corals [ 37 ], and waste deposit of a leaf-cutting ant [ 38 ]. The frequent association of members of the genus Rhodosporidiobolus with plant structures points to their ability to utilize lignin-derived compounds.…”

Low-Temperature Biodegradation of Lignin-Derived Aromatic Model Monomers by the Cold-Adapted Yeast Rhodosporidiobolus colostri Isolated from Alpine Forest Soil

The contribution of cold-adapted yeasts to the emerging field of lignin biovalorization has not yet been studied. The red-pigmented basidiomycetous yeast strain Rhodosporidiobolus colostri DBVPG 10655 was examined for its potential to degrade five selected lignin-derived aromatic monomers (syringic acid, p-coumaric acid, 4-hydroxybenzoic acid, ferulic acid, and vanillic acid). The strain utilized p-coumaric acid, 4-hydroxybenzoic acid, and ferulic acid not only as the sole carbon source; full biodegradation occurred also in mixtures of multiple monomers. Vanillic acid was not utilized as the sole carbon source, but was degraded in the presence of p-coumaric acid, 4-hydroxybenzoic acid, and ferulic acid. Syringic acid was utilized neither as the sole carbon source nor in mixtures of compounds. Biodegradation of lignin-derived aromatic monomers was detected over a broad temperature range (1–25 °C), which is of ecological significance and of biotechnological relevance.
