ABSTRACT:
The invention provides a process for preparing medium chain dicarboxylic acids by biochemical oxidation so that in particular C.sub.8 and C.sub.10 dicarboxylic acids are prepared from nontoxic levels of C.sub.8 -C.sub.14 fatty acids using a nitrogen-restricted yeast propagated in a carbon substrate containing growth medium. Preferably the fatty material is supplied to the yeast in the form of a glyceride. Also it is preferred that the amount of nitrogen in the biomass is between 4 and 9%, in particular between 5.5 and 7% (w/w).
