Chlorella carveol

Microalgae were used for oxidation and hydroxylation of organic compounds (Fig. 3). For example, hydroxylation of (5 )-limonene affords a mixture of cis and trans carveols. " By hydroxylation and oxidation using Chlorella, " ... 

On the other hand, the high enantioselectivity for 81a was observed in the biotransformation of racemic (+)-tra i-carveol (81a) and -)-trans-carveol (81a ) by Chlorella sorokiniana SAG to give (-) -carvone (93 ).

Enantio- and diastereoselective biotransformation of trans- (81a and 81a ) and c -carveols by Euglena gracilis Z. (Noma and Asakawa 1992) and Chlorella pyrenoidosa lAM C-28 was studied (Noma et al., 1997).
