Processes for transesterifying wax esters. Implementations may include providing a feedstock including wax esters, introducing into the feedstock an alcohol with a carbon number ranging from 1 to 34 carbons where the alcohol is selected from the group consisting of a straight chain alcohol, a branched chain alcohol, any combination of straight chain alcohols, any combination of branched chain alcohols, and any combination thereof. The process may include contacting the feedstock with a lipase, and catalytically transesterifying the wax esters in the feedstock with the lipase to form a transesterified product. The enzymatically transesterified product may be adapted to produce a finished product having a certain formula that has a viscosity that substantially matches a viscosity of a finished product having the same certain formula including chemically catalyzed transesterified wax esters.

Implementations may include: providing a feedstock including wax esters, contacting the feedstock with a lipase, and catalytically transesterifying the wax esters in the feedstock with the lipase to form a transesterified product. An oxidative stability index (OSI) of the transesterified product may be greater than an OSI of the feedstock.

A method for oxidizing an alkyl, including a) contacting the alkyl with an aqueous solution comprising a microorganism where the microorganism has a reduced fatty acid degradation capacity compared to its wild type, wherein the fatty acid degradation capacity is reduced by deletion, inhibition or inactivation of a gene encoding an enzyme involved in the β-oxidation pathway; and the microorganism expresses a recombinant alkane oxidase, and b) contacting the aqueous solution from a) with a water-immiscible organic solvent.
