Kluyveromyces marxianus has a high potential for industrial production of aroma compounds, such as 2-phenylethanol, which is derived in a bioconversion from L-phenylalanine. In the present work the product yield of K. marxianus in batch cultivation was estimated as 0.65 mol 2-phenylethanol/mol L-phenylalanine and thus significantly below the theoretical optimum of 1 mol/mol. By a comprehensive approach of stoichiometric balancing and GC-MS analysis of various substrates and products of K… CONTINUE READING
