Multiplex PCR was used to investigate the presence of enterotoxins genes (sea, seb, sec, sed and see) and femA gene (specific for Staphylococcus aureus) in coagulase-positive staphylococci (CPS) isolated from cheese and meat products. From 102 CPS isolates, 91 were positive for femA, 10 for sea, 12 for sed and four for see.
Micrococcaceae strains are applied to fermented sausage as starter cultures, where several members of this family are naturally found. The aim of the present work was to isolate and characterize Staphylococcus xylosus from artisanal sausages produced in South Region of Brazil. From 89 isolates presenting catalase positive and coagulase negative activities,(More)
Staphylococcus xylosus is a microorganism involved in fermentation of meat products and also a natural producer of extracellular lipases. The aim of the present work was to clone and express in E. coli a lipase from S. xylosus (AF208229). This lipase gene (1084 bp) was amplified from a S. xylosus strain isolated from naturally fermented salami and(More)
