3.2. Morphologic and growth characteristics of the selected
microorganisms
The selected yeasts after growing on agarized YPS proliferation
medium presented white-creamy colonies. When strains were
developed in liquid medium the strain A2 showed a homogeneous
and dispersed growth, whereas the growth of the strains A10 and
A11 wasflocculent. The biomass was associated forming clusters or
1 mm diameterflocs, being deposited at the bottom of the culture
flasks at the end of fermentation. The three strains were observed
by optical microscopy, showing the 3 isolates an ovoid shape, which
is characteristic in yeasts. It was also observed cell division by
gemmation and the absence of pseudomycelia (Fig. 2).
Furthermore, no significant differences were observed in th
