TL;DR: A Cr(VI)-resistant yeast was isolated from tanning liquors from a leather factory in Leon, Guanajuato, Mexico and showed ability to reduce Cr( VI), a phenotypic trait similar to that of Candida albicans.
Journal ArticleDOI
Hexavalent chromium removal in vitro and from industrial wastes, using chromate-resistant strains of filamentous fungi indigenous to contaminated wastes.

TL;DR: Two chromate-resistant filamentous fungi, strains H13 and Ed8, were selected from seven independent fungal isolates indigenous to Cr(VI)-contaminated soil because of their ability to decrease hexavalent chromium levels in the growth medium andQuantitative determinations of oxidized and reduced chromium species during the reduction process revealed stoichiometric conversion of Cr( VI) toCr(III).
Journal ArticleDOI
Abundance of airborne Penicillium CFU in relation to urbanization in Mexico City.
TL;DR: Air was sampled simultaneously at three localities in Mexico City differing in urbanization index and air pollution level on 22 days during a period covering both dry and rainy seasons to give concentrations of total fungal spores and of Penicillium spp.
Journal ArticleDOI
Microbiology of Indian and Mestizo pozol fermentations
TL;DR: Pozol is a beverage prepared from fermented nixtamal consumed in Southeastern Mexico and the number of micro-organisms in the initial doughs were quite constant day by day, and viable enterobacteria were still present at the end of the fermentation.
