Yeast diversity associated to sediments and water from two Colombian artificial lakes

Abstract

In Colombia, knowledge of the yeast and yeast-like fungi community is limited because most studies have focused on species with clinical importance. Sediments and water represent important habitats for the study of yeast diversity, especially for yeast species with industrial, biotechnological, and bioremediation potential. The main purpose of this study was to identify and compare the diversity of yeast species associated with sediment and water samples from two artificial lakes in Universidad del Valle (Cali-Colombia). Yeast samplings were performed from fifteen sediment samples and ten water samples. Grouping of similar isolates was initially based on colony and cell morphology, which was then complemented by micro/mini satellite primed PCR banding pattern analysis by using GTG5 as single primer. A representative isolate for each group established was chosen for D1/D2 domain sequencing and identification. In general, the following yeast species were identified: Candida albicans, Candida diversa, Candida glabrata, Candida pseudolambica, Cryptococcus podzolicus, Cryptococcus rajasthanensis, Cryptococcus laurentii, Williopsis saturnus, Hanseniaspora thailandica, Hanseniaspora uvarum, Rhodotorula mucilaginosa, Saccharomyces cerevisiae, Torulaspora delbrueckii, Torulaspora pretoriensis, Tricosporon jirovecii, Trichosporon laibachii and Yarrowia lypolitica. Two possible new species were also found, belonging to the Issatchenkia sp. and Bullera sp. genera. In conclusion, the lakes at the Universidad del Valle campus have significant differences in yeast diversity and species composition between them.

Diversity of yeasts and filamentous fungi in mud from hypersaline and freshwater bodies in Egypt.

“…Similar to the present finding, Candida albicans, C. pseudolambica, Rhodotorula mucilaginosa, Saccharomyces cerevisiae, but differently Candida diversa, C. glabrata, Cryptococcus podzolicus, C. rajasthanensis, C. laurentii, Williopsis saturnus, Hanseniaspora thailandica, H. uvarum, Torulaspora delbrueckii, T. pretoriensis, Trichosporon jirovecii, T. laibachii and Yarrowia lipolytica were recovered from sediment and water samples from two artificial lakes in Universidad del Valle (Cali, Colombia) (Silva-Bedoya et al 2014).…”

“…Hortaea werneckii was found in slope sediments of the Bay of Bengal on the east coast of the Indian peninsula, India (Kutty et al 2013b). Also, species of Candida, Cryptococcus, Williopsis, Hanseniaspora, Rhodotorula, Saccharomyces, Torulaspora, Trichosporon and Yarrowia lipolytica were recovered from sediment and water samples from two artificial lakes in Universidad del Valle (Cali, Colombia) (Silva-Bedoya et al 2014).…”

Yeasts from peat in a tropical peat swamp forest in Thailand and their ability to produce ethanol, indole-3-acetic acid and extracellular enzymes

“…A strain of Sa. (C.) diversa was reported to be obtained from grape must (Lachance et al 2011), and many strains of this species have recently been found in sediments and water from an artificial lake in Colombia (Silva-Bedoya et al 2014). Cryp.…”

Variations in Fungal Community and Diversity in Doushen With Different Flavors

“…These fungi have been identified in tea, olive cake, fruit juice, and other agricultural products and can produce amylase, xylanase, and cellulase (Adams, 1992;Wareing, 1997;Ping et al, 2018). Bullera, a genus belonging to Ballistosporous, can produce conidia and are present in diverse plants (phyllosphere), dairy products, and various environments (Nakase, 2000;Mushtaq et al, 2013;Silva-Bedoya et al, 2014). Some species of Bullera are producers of β-galactosidase, toxins, and coenzyme Q 10 (Golubev and Nakase, 1998;Cho et al, 2003).…”
