Lactate dehydrogenase (LDH) was crystallized from concentrated ammonium sulfate solution and cross-linked with glutaraldehyde to afford long-lived enzymatically active cross-linked crystals (LDH-CLC). The crystals were employed in an electrolytic cell for lactate production from pyruvate, in which the cathode consisted of a carbon electrode containing a coating of lipoamide dehydrogenase (LiDH) immobilized with methyl viologen under a Nafion membrane. This cell was more effective than a similar cell containing LDH in soluble form. An even greater improvement in performance was achieved by chemically binding a viologen derivative to the LiDH and using an electrode based on this modified enzyme in a cell containing LDH-CLC. The activity of the LDH-CLC is much less sensitive to pH than that of the soluble enzyme.

Menthyl lactate process

Page/Page column 5-8, (2008/06/13)
A simple, high-yield process for making menthyl lactate (ML) is disclosed. Menthol and lactic acid react to produce a mixture comprising menthyl lactate and one or more higher lactoyl esters of ML. Hydrolysis of the esterification mixture follows in the presence of aqueous base under conditions effective to convert the higher lactoyl esters to menthyl lactate. Coincidentally, the conditions minimize hydrolysis of menthyl lactate to menthol, thereby maximizing the overall yield of ML.
