The role of carotenoids in suppression of oxigen reactive species in red alga Porphiridium Cruentum

Abstract

Reaction of any living organisms, including the unicellular in case of xenobiotic interventions and life conditions modification is expressed in modifying of antioxidant status, which tends to maintain homeostasis and elimination of induced oxidative stress status. Antioxidant components of the living cell are the first who react to any changes, so it is possible to determine the early changes in normal reaction and requires the further development of events that will take place. In the experiments with oxidative stress, microalga Porphyridium cruentum was grown in conditions of cultural medium supply with compounds of Fe (III) with the Schiff base and dioximes, in concentration of 20 mg / l. The production of biomass for the majority of samples was under the blank limit with 20-40%.
