MESA C, Luz Mila et al. Comparison of the growth of Malassezia furfur and Malassezia slooffiae on Spondias dulcis gum exudate and Dixon media. Kasmera [online]. 2008, vol.36, n.1, pp.45-52. ISSN 0075-5222.

Malassezia yeasts are fungi that produce skin affections. Growth of these microorganisms requires specific conditions. The Dixon medium has generally been used for their culture and has been tested. The use of Spondias gum as a substrate for Malassezia furfur and Malassezia slooffiae was tried and compared with the Dixon medium. The growth kinetic for a given time range(0-120 h) was determined at different concentrations (1.2%) and pH levels (4,0; 6,0;7,0). The relatively high biomass obtained for the two tested yeasts demonstrated that the substrate prepared with S. dulcis gum exudate is suitable for their growth. Spondias dulcis, a species located in Venezuela, yields abundant gum. This fact and the results discussed above indicate that it could be used to prepare a substrate that could compete with Dixon for isolating and characterizing the Malassezia species.

Palabras clave : Malassezia furfur; Malassezia slooffiae; Spondias dulcis gum exudate; substrate.
