Abstract: Disclosed are an enzymatic batchwise or continuous process for the production of fatty acid alkyl esters for use in the biofuels, food and detergent industries and a system therefor. The process utilizes enzymes immobilized on a hydrophobic resin mixed with a fatty acid source and an alcohol or alcohol donor in the presence of an alkaline or mild alkaline aqueous buffer, or in the presence of water or aqueous solution. The production process for fatty acid alkyl esters is carried out by transesterification or esterification simultaneously or sequentially. The biocatalyst activity is maintained with no significant activity losses in multiple uses and also avoids the accumulation of glycerol and water by-products or other hydrophilic compounds on the biocatalyst.

Abstract: Disclosed are preparations of modified interfacial enzymes, particularly lipases and phospholipases, immobilized on a solid support, wherein the enzyme is surrounded by hydrophobic microenvironment, thereby protected from deactivation and/or aggregation in the presence of hydrophilic agents, substrates and/or reaction products. The enzyme may be protected by being covalently bonded with lipid groups which coat the enzyme, or by being immobilized or embedded in a hydrophobic solid support. Also disclosed are processes for the preparation of the hydrophobically protected enzymes. The enzymes may be efficiently used in the preparation of biodiesel.

Abstract: Disclosed is a process for the preparation of an interfacial enzyme immobilized on an insoluble support, by providing a bi-phase system comprised of an aqueous buffer solution and at least one first organic solvent; mixing said interfacial enzyme with the bi-phase system provided; adding the support to the obtained mixture and mixing; and isolating from the mixture obtained in the last step the interfacial enzyme immobilized on said support. The produced enzyme is locked in its catalytically active confirmation, and thus exhibits improved activity and stability. Also disclosed are uses of the produced enzymes, particularly in the preparation of biodiesel.

Abstract: Disclosed is an enzymatic process for the preparation of fatty acid alkyl esters, particularly fatty acids methyl esters (biodiesel) in a solvent-free microaqueous system, from a fatty acid source and an alcohol or alcohol donor, employing a robust lipase preparation that comprises at least two lipases separately or jointly immobilized on a suitable support, where one of the lipases has increased affinity to partial glycerides, another is sn-1,3 positional specific, and an optional third lipase has high selectivity towards sn-2 position of the glycerol backbone of the fatty acid source.
