Statutul antioxidant în corelare cu componenţa biochimică a biomasei unor microalge în condiţii de tehnologii intensive

Abstract

The coordination compounds of Fe (III) with Schiff bases cause the Porphyridium cruentum biomass reduction and Haematococcus pluvialis biomass increasing in case of application of the mentioned compounds in an amount of 20 mg / l. Between antiradical activity of extracts from biomass and the amount of malonic dialdehyde was detected a moderate inverse correlation to Porphyridium cruentum, and a close correlation to Haematococcus pluvialis. The amount of carotenoids in microalgae biomass correlate with antiradical activity of ethanol extracts, being the major components with antiradical effect both in porfiridium and hematococcus biomass.
