- Abstract
Chemically, biodiesel is obtained from the trans esterification of vegetable oil or animal fat, in the presence of alcohol, such as methanol or ethanol, generating glycerol as by product. The aim of this work was to test the capacity of several halophilic microorganisms to grow on culture media supplemented with waste glycerol, derived from different sources (Mediaş and Slobozia), and to produced lipases and decarboxylases used as biocatalysts to convert residual glycerol to valuable compounds. From a total of 30 halophilic bacterial strains, isolated from Balta Albä, Buzäu County, and Techirghiol salt lakes, a number of eight halophilic/halotolerant strains showed lipolytic activity. Marinococcus halophilus strain JCM 2472, a moderately halophilic bacteria, was used in this study for its capacity to synthesized extracellular lipases and decarboxylases.
