(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em BiotecnologiaUTFPR, 2020-10-15)
Many microbial species are acknowledged by their ability to provide distinct organoleptic properties to countless foods and drinks, especially alcoholic beverages. Non-conventional yeasts stand out in using different ...
Interaction of Copper or Chromium with Yeasts: Potential Application on Polluted Environmental Clean Up
(Nova Science Publishers, 2011)
Heavy metal pollution is one the most serious environmental problems. Mining and industrial activity are the main sources of heavy metal contamination. Heavy metals, such as copper (Cu) and chromium (Cr), play an important ...
Caracterização de fungos presentes em solos sulfetados da Antártica e sua avaliação para estudos em processos de biolixiviação de metais
