Abstract
Methanol-consuming yeasts have an FAD-dependent methanol oxidase, which catalyzes the reaction between methanol and oxygen to form formaldehyde and hydrogen peroxide. The catalâse that is present in the same peroxisomes decomposes the hydrogen peroxide; it also acts as a formaldehyde producer by oxidation of the methanol (1,2). A subsequent enzymatic step incorporates formaldehyde into different metabolic pathways through an NADH2 - dependent formaldehyde dehydrogenase, which requires a mechanism for NAD regeneration. Therefore, non-viable cells will not decompose formaldehyde since the NAD cannot be regenerated (1).
