RESUMO
Studies were carried out to explore the possibility of decreasing the toxic and inhibitory effects of the substrate benzaldehyde during its biotransformation to L-PAC by free cells of Torulaspora delbrueckii using beta -cyclodextrin (beta -CD). Use of various levels of benzaldehyde and acetaldehyde in presence of 2% of beta -CD showed that, in presence of beta -CD, the organism could tolerate higher levels of benzaldehyde and acetaldehyde. Semi-continuous feeding of benzaldehyde and acetaldehyde was found to increase the yield of L-PAC in comparison with one time feeding.
