Web13 Citations Metrics Abstract Conversion of benzaldehyde to l-phenylacetyl carbinol (l-PAC) was achieved with immobilized, growing cells of Saccharomyces cerevisiae in different reactors. Product formation increased (31%) with the subsequent initial reuses of the entrapped cells. WebJan 1, 1989 · Summary. The rate of production of l-phenylacetyl carbinol bySaccharomyces cerevisiae in reaction mixtures containing benzaldehyde with sucrose or pyruvate as cosubstrate was investigated in short 1 h incubations. The effect of yeast dose rate, sucrose and benzaldehyde concentration and pH on the rate of reaction was determined.
Phenylacetylcarbinol (PAC) is an organic compound that has two enantiomers, one with R- and one with S-configuration. (R)-PAC, which is commonly called l-PAC, is known as a precursor in the synthesis of pharmaceuticals such as ephedrine and pseudoephedrine. See more (R)-PAC or (R)-(−)-phenylacetylcarbinol is identical to l-PAC, referring to the outdated d/l system. (R)-PAC is the levo-rotating isomer of phenylacetylcarbinol. The IUPAC name of phenylacetylcarbinol is 1-hydroxy-1 … See more (R)-PAC is widely synthesized by fermentation of benzaldehyde and dextrose.
