Abstract: Disclosed is a method for synthesis of fatty acids by culturing a eukaryotic microorganism from the fungi kingdom, that is naturally oleaginous or rendered oleaginous. The culture is performed in the presence a fatty acid synthase inhibitor in the culture medium.

Abstract: Method for simultaneous selection and maintenance of a selected microbial consortium for polyhydroxyalkanoates (PHA) production in only one step, said microbial consortium being fed with at least one readily biodegradable carbon substrate, comprising a first step of aerobic cultivation of said microbial consortium in a mixed biological reactor. According to the invention, the specific cell growth rate ?l of said microbial consortium is fixed at a target value, in said first step of aerobic cultivation and in that said first step of aerobic cultivation is performed under nutrient limitation such as the readily biodegradable carbon substrate uptake rate qS1 unbalanced with said fixed specific cell growth rate ?1.

Abstract: Method for producing Yarrowia lipolytica acid-resistant recombinant lipase utilizing a culture medium without any products of animal origin or non-characterized mixtures such as tryptone, peptone or lactoserum, in addition to its uses. Recombinant strain of Yarrow lipolytica producing an excessive amount of lipase Lip2 referred to as YL-LIP2-6C and filed with the Collection Nationale de Cultures de Microorganismes (C.N.C.M.) under number I 3542, on Dec. 15, 2005 and its uses.
