Resumen
Because of its outstanding biological and industrial importance, many efforts have been
made to characterize the mycobiota of new environments and their biochemical and biotechnological
potentials. Gut mycobiota can be a source of novel yeasts with the potential to be used as probiotics or
have industrial applications. In this work, we characterized two as-yet unexplored yeast communities
from the intestinal content of the cultured marine Chilean fishes Genypterus chilensis (G. chilensis)
and Seriolella violacea (S. violacea). Yeasts were isolated through culture, identified by sequencing
their ITS region, and characterized their enzymatic profile with API®ZYM. Rhodotorula mucilaginosa
was identified in both fish species. For the first time, Candida palmioleophila, Candida pseudorugosa,
Cystobasidium slooffiae, and a member of the Yamadazyma genus were also identified and described
as part of the normal fish gut–microbiota. Furthermore, the diverse enzymatic profile exhibited by
some of these isolates suggests that it may be possible to develop novel applications for them, such
as new probiotics and other biotechnological applications.
