Improving ethanol production by co-culturing of Saccharomyces cerevisiae with Candida tropicalis from rice husk hydrolysate media

The use of agricultural by-product as feed stock and co-culture fermentation is a good strategy for improving the efficiency of fermentation and ethanol production. Most rice husks have low protein and nitrogen content and need to be supplemented with nitrogen for fermentation process. This research sought to determine the optimal supplementation of rice husk stream–based fermentation medium with nitrogen and...

Engineered microbial consortium for the efficient conversion of biomass to biofuels: A preliminary study

This work showed ethanol production by a microbial consortium of Clostridium cellulolyticum and a recombinant Zymomonas mobilis (ZM4 pAA1). The ZM4 pAA1 and wild type ZM4 (ZM4 WT) were first tested on RM medium (ATCC 1341) containing 2% cellobiose as the carbon source. Ethanol production from ZM4 pAA1 was three times higher than that observed from the ZM4 WT. Concomitant with ethanol production was the reduction in OD...

Antibiotic resistance and molecular characterization of Staphylococcus species from mastitic milk

Species within the Staphylococcus genus are important mastitis pathogens. Studies to describe virulence and antibiotic resistance as well as rapid techniques that permit analyses strains are needed. The aims were to identify and characterize Staphylococcus spp. isolated from mastitic milk, and to optimize multiplex polymerase chain reactions (PCR). Staphylococci previously isolated from milk of dairy cows with...

Diversity and distribution of the endophytic fungal community in eucalyptus leaves

Eucalyptus species are among the most widely grown and most economically valuable trees worldwide. In Brazil, eucalyptus is of major environmental and economic importance because it generates thousands of jobs and offers an alternative to using wood from native forests. In forest ecosystems, plant shoots are considered a common habitat for various microorganisms, and plants of the family Myrtaceae are an important...

Dual-path platform (DPP) and enzyme-linked immunosorbent assay (ELISA): Change the sequence of the tests does not change the number of positive dogs for canine visceral leishmaniasis

The Brazilian Ministry of Health determined in 2012 that the official protocol for diagnosis of Canine Visceral Leishmaniasis (CVL) would be the Dual-Path Platform (DPP) for screening, followed by enzyme-linked immunosorbent assay (ELISA) for confirmation. This study evaluated serum samples from 426 dogs from a region in northern Brazil. All samples were tested according to the Official Protocol and the sequence...
