Although some authors have concluded that tissue lipases are primarily responsible for lipolysis during fermentation, numerous studies over the last decade described lipolytic bacteria, especially staphylococci Hugas and Monfort (1997) highlighted the need to use selected strains of Gram-positive, catalasepositive cocci to ensure sensory quality of fermented sausages, Moreover, Stahnke et al.(2002), Beck et al. (2004), and olesen et al. (2004) described the capability of Staphylococcus xylosus and Staphylococcus carnosus strains to modulate the aroma through the conversion of amino acids and free fatty acids (FFA) Strains of S. xylosus have been recommended for the production of the very aromatic sausages of southern Europe (Samelis et al. 1998).
