Disclosed is an improved process for the production of fatty acid lower alkyl esters according to formula (I)RCO&#x2014;OR&#x2003;&#x2003;(I)in which RCO represents a linear or branched acyl moiety having from about 6 to about 22 carbon atoms and 0 to 6 double bonds and wherein Ris a linear or branched alkyl moiety having 1 to 6 carbon atoms, by transesterification of triglycerides or fatty acid esters using C-Caliphatic alcohols, which includes the steps of The products thus obtained are particularly useful as components of the fuel known as biodiesel.

Process for the production of fatty acid alkyl esters

The invention concerns compositions and methods combining at least two phytases for hydrolyzing phytic acid (myo-inositol hexakis phosphate) into inorganic monophosphates, into myo-inositols with lower degree of phosphorylation and into free myo-inositol. Said compositions and methods are of particular interest for animal feeding.

Synergetic effect of the phytase combination on the hydrolysis of phytic acid

A reaction medium for enzyme-catalyzed reactions is provided, comprising an oil-in-water emulsion including water, an emulsifier, an oil phase and at least one interfacially active enzyme, where the emulsion is produced by the phase inversion temperature process and has a droplet size of 50 to 400 nm. A method for the enzyme-catalyzed esterification, transesterification or hydrolysis of fatty acid alkyl esters and/or triglycerides is also provided where the oil-in-water emulsion is used as the reaction medium.

Emulsions in enzymatic reactions

Polypeptides comprising a polypeptide chosen from the group consisting of the polypeptide of SEQ ID No. 2 and a polypeptide exhibiting at least 90% identity with the polypeptide of SEQ ID No. 2. Polynucleotides selected from the group consisting of the polynucleotide whose sequence is between position 1538 and position 2923 of SEQ ID No. 1, and a polynucleotide encoding the polypeptide chosen from the group consisting of the polypeptide of SEQ ID No. 2 and a polypeptide exhibiting at least 90% identity with the polypeptide of SEQ ID No. 2. Furthermore, vectors and expression cassettes comprising the polynucleotide.

[object Object]

Polypeptides with lipase/acyltransferase activity are described with an amino acid sequence which has identity to the sequence reported in SEQ ID NO 2 of at least 49%, also polypeptides which display this activity, as well as nucleic acids (genes) which code for these polypeptides, vectors which contain nucleic acids which code for these polypeptides, transformed microorganisms which contain these nucleic acids, processes for production of these polypeptides and the application of nucleic acids for discovering new lipase/acyltransferases and the use of these lipase/acyltransferases as catalysts in chemical and biochemical processes.
