Disclosed are methods for preparing phenolic branched chain fatty acids or alkyl esters thereof, involving subjecting in a pressurized container (a) at least one phenolic compound, (b) unsaturated fatty acids having 6 to 25 carbon atoms, alkyl esters thereof, or mixtures thereof, and (c) H-ferrierite zeolite catalyst in the presence of distilled water or alcohol and a nitrogen atmosphere at a temperature of about 100&#xb0; C. to about 400&#xb0; C. and a pressure of about 10 to about 1000 psi, and isolating saturated phenolic branched chain fatty acids or alkyl esters thereof or mixtures thereof. Also disclosed are methods for killing microorganisms on or in an object, involving contacting said object with an effective microorganisms killing amount of a composition comprising phenolic branched chain fatty acids or alkyl esters thereof, and optionally a carrier; the phenolic branched chain fatty acids or alkyl esters thereof may be produced by the methods described herein.

Methods for preparing phenolic branched chain alkyl fatty acids or esters thereof and methods for killing microorganisms

The present invention relates to a method for producing fatty acid alkyl esters, involving transesterifying a feedstock containing lipid-linked fatty acids with an alcohol and an alkaline catalyst to form fatty acid alkyl esters. The feedstock has not been previously treated to release the lipid components of said feedstock, or the feedstock has been previously treated to release lipid components and the feedstock contains residual lipids (e.g., &#x3c;about 30% of the original content of lipids).

Production of fatty acid alkyl esters

The present invention relates to a method for producing fatty acid alkyl esters, involving esterifying a material containing free fatty acids (FFA) with an alcohol and an inorganic acid catalyst to form a product containing fatty acid alkyl esters, wherein (i) the material contains at least about 40% FFA and is produced by reacting a feedstock with steam and sulfuric acid at a pH of about 1-about 2 or (ii) the material contains at least about 80% FFA and is produced by reacting a feedstock with steam and alkali at a pH of about 11-about 13 and further reacting the feedstock with steam and sulfuric acid at a pH of about 1-about 2. The feedstock may be selected from the oils or soapstocks of soy, coconut, corn, cotton, flax, palm, rapeseed/canola, safflower, sunflower; animal fats; waste greases; and mixtures thereof; or other fully or partially hydrolyzed preparations of such feedstocks. The present invention also relates to a method for producing a lipid rich composition containing at least about 80% FFA, the method involving reacting a feedstock with steam and alkali at a pH of about 11-about 13 and further reacting the feedstock with steam and sulfuric acid at a pH of about 1-about 2. The feedstock may be selected from soy, coconut, corn, cotton, flax, palm, rapeseed/canola, safflower, sunflower, animal fats, waste greases, and mixtures thereof. The feedstock may be selected from the oils or soapstocks of soy, coconut, corn, cotton, flax, palm, rapeseed/canola, safflower, sunflower; animal fats; waste greases; and mixtures thereof; or other fully or partially hydrolyzed preparations of such feedstocks. Furthermore, the present invention concerns a lipid rich composition containing at least about 80% FFA.

Process for the production of fatty acid alkyl esters

A method of producing fatty acids and glycerol from oleaginous materials utilizing comminuted seeds as an immobilized lipase catalyst. The comminuted lipase-containing seeds are combined with an oleaginous material, an organic solvent and water with the resultant heterogenous mixture being agitated under non-energy intensive conditions to provide free fatty acids and glycerol. The lipase catalyst may be recovered and recycled.

Method of rapid fat and oil splitting using a lipase catalyst found in

The present invention describes a method of producing biofuels by carrying out the enzymatic transesterification of fatty acid-containing materials directly in automotive fuels.

Fuels as solvents for the conduct of enzymatic reactions

A lipase purified from Rhizopus delemar can be produced by cultivating a genetically engineered host microorganism transformed with a gene coding for the lipase. Additionally disclosed is a method for the detection or screening for production of lipase by genetically engineered organisms.
