A. Lomascolo et al., Enhanced benzaldehyde formation by a monokaryotic strain of Pycnoporus cinnabarinus using a selective solid adsorbent in the culture medium, CAN J MICRO, 45(8), 1999, pp. 653-657
A monokaryotic strain of the white-rot fungus Pycnoporus cinnabarinus was s
hown to produce, in a 2-L bioreactor culture, 100 mg.L-1 benzaldehyde (bitt
er almond aroma) from L-phenylalanine with a productivity of 33 mg.L-1.day(
-1). The addition of HP20 resin, a styrene divinylbenzene copolymer highly
selective for benzaldehyde, enabled an eightfold increase in the production
of benzaldehyde and a twofold increase in productivity. In the presence of
HP20 resin, the production of 790 mg.L-1 benzaldehyde was concomitant with
the synthesis of cinnamic acid derivatives of high organoleptic notes such
as cinnamaldehyde, cinnamyl alcohol, and methyl cinnamate.
