“…The region features different types of vegetation, ranging from dense forests to savannahs and mountain refuges. Several works have been published on the yeast diversity in Amazonian rainforest biomes (Barriga et al, 2014;Barros et al, 2023;Cadete et al, 2012;Guamán-Burneo et al, 2015;Jacques & Casaregola, 2019;James et al, 2009James et al, , 2013Lopes et al, 2018;Matos et al, 2021;Mok et al, 1984;Morais, Rosa, et al, 1995;Neves et al, 2006;Vital et al, 2001). Most of these works show that the Amazonian rainforest biome is a vast source of novel yeasts.…”

Tropical rainforests and related biomes are found in Asia, Australia, Africa, Central and South America, Mexico, and many Pacific Islands. These biomes encompass less than 20% of Earth's terrestrial area, may contain about 50% of the planet's biodiversity, and are endangered regions vulnerable to deforestation. Tropical rainforests have a great diversity of substrates that can be colonized by yeasts. These unicellular fungi contribute to the recycling of organic matter, may serve as a food source for other organisms, or have ecological interactions that benefit or harm plants, animals, and other fungi. In this review, we summarize the most important studies of yeast biodiversity carried out in these biomes, as well as new data, and discuss the ecology of yeast genera frequently isolated from tropical forests and the potential of these microorganisms as a source of bioinnovation. We show that tropical forest biomes represent a tremendous source of new yeast species. Although many studies, most using culture‐dependent methods, have already been carried out in Central America, South America, and Asia, the tropical forest biomes of Africa and Australasia remain an underexplored source of novel yeasts. We hope that this review will encourage new researchers to study yeasts in unexplored tropical forest habitats.

“…In 1976, Porter (1976) determined that ~30 % of all vascular plant species found in the Galápagos have a Neotropical origin. Remarkably in their more recent study, Carvajal Barriga et al (2014) identified that 31 % of the yeast species isolated on the Galápagos Islands were also found on mainland Ecuador. This would indicate that plant dispersal may have played an important role in the dispersal of yeast species from the mainland to the archipelago.…”

“…An ecological analysis of the Ecuadorian yeast strains registered in the CLQCA database was performed recently in order to develop a simple mathematical model for calculating how well individual yeast species have adapted to the differing habitats found in Ecuador (Carvajal Barriga et al , 2014). In this study, a set of 881 yeast strains, representing 104 species, was analysed using a mathematical approach which focused on the number of different natural regions of Ecuador each species was found to colonize as well as the number of different types of substrate from which they had been isolated.…”

“…Thus, the higher the Si value, the more specialized the yeast species. In Ecuador it was possible to find yeast species exhibiting Si values ranging from 0.02 (generalist) to 0.92 (specialist) (Carvajal Barriga et al , 2014).…”

“…nov., the Si value was calculated to be 0.62. This meant it grouped with the majority of yeast species (67 %) analysed which were found to be highly specialized and restricted to a small number of habitats and substrates, both on mainland Ecuador and in the Galápagos archipelago (Carvajal Barriga et al , 2014). Other species sharing the same Si value as Kazachstania yasuniensis sp.…”

Seven strains representing a novel yeast species belonging to the genus Kazachstania were found at several collection sites on both mainland Ecuador (Yasuní National Park) and the Galá pagos (Santa Cruz Island). Two strains (CLQCA 20-132 T and CLQCA 24SC-045) were isolated from rotten wood samples, two further strains were isolated from soil samples, and three strains were isolated from decaying fruits. Sequence analyses of the D1/D2 domains of the LSU rRNA gene and ribosomal internal transcribed spacer (ITS) region indicated that the novel species is most closely related to Kazachstania servazzii and Kazachstania unispora. Although the strains could not be distinguished from one another based upon their differing geographical origins, they could be differentiated according to their isolation source (fruit, soil or wood) by ITS sequencing. The species name Kazachstania yasuniensis sp. nov. is proposed to accommodate these strains, with CLQCA 20-132 T (5CBS 13946 T 5NCYC 4008 T ) designated the type strain.>The genus Kazachstania was first proposed by Zubkova in 1971 with the description of Kazachstania viticola, a yeast isolated from fermenting grapes in Kazachstan . Later in the same decade, the taxonomic status of Kazachstania viticola was reassessed by Von Arx et al. (1977), and it was considered to be a synonym of Saccharomyces dairenensis. However, the genus was reintroduced and redefined in 2003(Kurtzman, 2003 to accommodate Kazachstania viticola (type species) and 19 other species from the genera Arxiozyma, Kluyveromyces, Pachytichospora and Saccharomyces (sensu lato). This resulted from a detailed multigene sequence analysis carried out by Kurtzman & Robnett (2003) to examine the phylogenetic relationships and genus boundaries of the approximately 80 species belonging to the 'Saccharomyces complex'. In the most recent (fifth) edition of The Yeasts, A Taxonomic Study, 32 species were listed as belonging to the genus (Vaughan-Martini et al., 2011). Since then, the genus has continued to increase in size as additional species have been discovered and described including Kazachstania bromeliacearum, Kazachstania ichnusensis, Kazachstania intestinalis, Kazachstania pyschrophila, Kazachstania rupicola, Kazachstania taianensis and Kazachstania wufongensis (Lee et al., 2009;Chen et al., 2010;Suh & Zhou, 2011;Araú jo et al., 2012;Cardinali et al., 2012; Kabisch et al., 2013; Safar et al., 2013).On the basis of multigene sequencing, using both nuclearand mitochondrial-encoded genes, Kurtzman & Robnett (2003) resolved the genus into three main lineages (see Fig. 1 of Kurtzman & Robnett, 2003).
