Reverse phase HPLC chromatogram showing the carotenoids extracted from P. rhodozyma cells grown with (+ Cu culture) and without Cu+2 (− Cu culture). The yeast cells were recovered at 30 and 72 h, just at the onset of ethanol accumulation and after the exhaustion of ethanol, respectively. Peak 1 represents astaxanthin in all instances. Peak 8 in − Cu, 30 h; peak 10 in + Cu, 30 h and peak 9 in + Cu, 72 h correspond to β-carotene. All other peaks correspond to intermediary unknown carotenoids. Peak detection wavelength was at 480 nm using a diode arrangement detector
