Abstract
The biotechnological potential of yeasts associated to different habitats in Colombia has been poorly studied, especially the yeasts associated with different plant structures. Fruit pulps are interesting substrates mainly for the growth of yeast species, that can positively affect the productivity and quality of some bioeconomic species. Therefore, the objective of this study was to identify the dominant yeast species associated with mango and rose apple fruit pulps in Cali, Colombia. A total of 90 isolates were obtained, which were grouped considering their colony morphology. The D1/D2 domain of the large ribosomal RNA gene (LSU rRNA gene) or internal transcribed spacer (ITS) 1, ribosomal gene 5.8S and ITS 2 (ITS) regions of one to several representative isolates from each group was sequenced and compared with type strains for identification. The species Hanseniaspora thailandica, H. opuntiae and Clavispora lusitaniae were reported as shared by both fruits, specific for rose apple (H. uvarum, Pichia terricola, Rhodosporidiobolus ruineniae and Candida albicans), or for Mango (Meyerozyma caribbica, M. guilliermondii, C. natalensis, Aureobasidium pullulans, Pichia sp., Saturnispora diversa and C. jaroonii). Two morphotypes were not identified at the taxonomic level of species and were reported as candidates for new species, belonging to the genera Wickerhamomyces and Pichia.
Highlights
Yeasts have been reported in almost all natural and artificial ecosystems
Yeasts were obtained between 2010 and 2011 from the pulps of mango and rose apple fruits in Santiago de Cali, Colombia. This city is framed within a climate of tropical valley, with precipitation up to 1200 mm, average temperature of 26oC, minimum of 19oC and maximum of 34oC. 50 mangoes were picked from a fruit distribution center and 50 rose apples were randomly collected at Universidad del Valle
It should be noted that the sampling and development of the research was culturedependent, so the analyses of different species found are biased by the type of methodology used
Summary
Yeasts have been reported in almost all natural and artificial ecosystems. The conditions that prevail in each substrate determine the ecology, metabolic activity, growth and survival of different yeastBiological SciencesAn Acad Bras Cienc (2019) 91(4)MAURICIO RAMÍREZ-CASTRILLÓN et al.YEASTS FROM MANGO AND ROSE APPLE IN CALIB1, B2, and vitamin C (ascorbic acid) (at: http:// www.traditionaltree.org/). Yeasts have been reported in almost all natural and artificial ecosystems. The conditions that prevail in each substrate determine the ecology, metabolic activity, growth and survival of different yeast. YEASTS FROM MANGO AND ROSE APPLE IN CALI. Vitamin C concentrations decrease, and glucose, fructose and sucrose levels increase (reported here as oBrix), which can be used by fermentative yeasts. In this sense, the fermentative capacity, enzymatic activity and other physiological properties of yeasts are of interest and have been extensively explored in other countries (Pampulha and Loureiro 1989, Palnitkar and Lachke 1990, Mejía et al 2009, Thierfelder et al 2011). In Colombia the composition or biotechnological potential of these yeasts is less documented (Ulloa et al 2009)
