- ... A recently proposed pathway for heme b biosynthesis, common to diverse bacteria, has the conversion of two of the four propionates on coproheme III to vinyl groups as its final step. This reaction is catalyzed in a cofactor-independent, H₂O₂-dependent manner by the enzyme HemQ. Using the HemQ from Staphylococcus aureus (SaHemQ), the initial decarboxylation step was observed to rapidly and obligate ...

- ... Microbial contamination is a problem in food industry. The effects produced by the metabolic activity of yeasts are diverse. If they are found in high numbers it might affect the organoleptic quality of the product. Zygosaccharomyces is the most frequent contaminant genus in sweetened juices that are not properly processed and stored. The aim of this work was to compare the action of five commerci ...
