Typical progress of culture broth pigmentation of ammonium limited grown Pencillium ochrochoron CBS123823 bioreactor batch cultures in dependence on the illumination conditions. Cuvettes show the single sampling time points in ascending chronology, i.e. cuvette left sampling time point t = 0 h, cuvette right sampling time point t = 90 h. A darkness, B red light (λpeak = 660 nm), C blue light (λpeak = 451 nm), D ambient (white) light (4100 K)
