A brief history of the ethnological and microbiological
aspects of pulque, beverage prepared by fermentation of the agave
or "maguey .. juice (Agave sa1miana Otto and other species of the
same genus) is made . Yeasts were isolated and registered from both
types of pulque studied: white or natural pulque and oat cured
pulque, and also from a mixture of oat and other ingredients added
to the first type of pulque to obtain the last mentioned beverage.
The following species of yeasts were identified: Candida
co11icu1osa, c. rugope11icu1osa, C. rugosa, C. va1ida,
K1uyveromyces marxianus var. bu1garicus, K. marxianus var. 1acti•,
Saccharomyces cerevisiae race aceti and S. cerevisiae race
g1obosus, all of them present in the white or natural pu.lque; the
same were 1solated from the oat-cured pulque except C. co11icu1osa,
C. va1ida and K. marxianus var . 1actis, and only the two varieties
of K1uyveromyces marxianus were isolated from the mixture of oat
and other ingredients
