Pichia pastor

Nevertheless, for the production of the flavour-active aromatic alcohol derivatives, such as the corresponding aldehydes and acids, metabolic engineering approaches have to compete with conventional oxidative biocatalysis starting from the natural alcohol as a substrate. For instance, the whole-cell oxidation system based on Pichia pastor is AOX already described in Sect. 23.4.1.2 can also be used to convert benzyl alcohol to benzaldehyde in aqueous media although product inhibition restricted the final product concentration to about 5 g L h indicating the need for aqueous-organic two-phase reaction media [51]. Phenylacetalde-... 

Piovesta s alcohol oxidase, from the yeast Pichia pastor is. Described as "equally active on methanol and ethanol" (D. Ranasiak arid T. Hopkins, Provest a, personal communication) it is "one-third as active no ethanol than on methanol.." on an enzyme electrode (Hopkins and Muller (in )). The commercial product is virtually devoid of catalase and has a pH stability profile (5. -8. 3) that see/n.s to rule out its use in beer or wines. Alcohol oxidase is still of interest...
