Fig. 7. Protective effect of PmPV1 against astaxanthin damage as a function of time. Samples
were exposed to air, fluorescent light and 35 °C for 470 min. Free astaxanthin was
more sensitive to photooxidation than combined astaxanthin. The absorbance was recorded
as Abs(t) / Abs(t0). λ = 492 nm. : PmPV1; : reconstituted PmPV1; : free
astaxanthin. Data represents the mean of three determinations ± SD.
