In this study, the phylogenetic relationships between cachaça strains of Saccharomyces cerevisiae isolated from different geographical areas in Brazil were obtained on the basis of sequences of one mitochondrial (COX2) and three nuclear (EGT2, CAT8, and BRE5) genes. This analysis allowed us to demonstrate that different types of strains coexist in ...
The aim of this study was to evaluate the chemical composition of sugar cane spirits, fermented by different commercial Saccharomyces cerevisiae yeast strains and double distilled by pot still. Sugar cane juices were separately fermented by yeasts CA-11, Y-904, BG-1, PE-2, SA-1 and CAT-1 and distilled by pot still according to the methodology used ...

We used a cultivation-independent, clone library-based 16S rRNA gene sequence analysis to identify bacterial communities present during traditional fermentation in sour cassava starch, cachaça and cheese production in Brazil. Partial 16S rRNA gene clone sequences from sour cassava starch samples collected on day five of the fermentation process ind...

During the production of traditional cachaça (alembic´s cachaça), contamination of the fermented must is one of the factors leading to economic losses in the beverage manufacturing industry. The diversity of bacterial populations and the role of these microorganisms during the cachaça production process are still poorly understood in Brazil. In our...
This work describes a simple and fast method for the direct and simultaneous determination of Al, As, Fe, Mn and Ni in cachaça by graphite furnace atomic absorption spectrometry (GFAAS). The upside of platform of the graphite tube was coated with a W-based film (W xCyOz). The optimized heating program (temperature, ramp time, hold time) involved th...

Besides its economical and social importance, there are very few studies, about the Brazilian sugar cane spirit, or cachaça, quality. This Brazilian beverage is very quite appreciate by its typical aroma and flavor, that can be improved by aging in wood recipes. The complex process that occurs during the aging depends, among various things, on the ...
