    ACTIVITATEA ANTIOXIDANTĂ A PREPARATULUI ETANOLIC ÎN BAZA BIOMASEI DE PORPHYRIDIUM CRUENTUM
    (CEP USM, 2014) Sadovnic, Daniela; Cepoi, Liliana; Rudi, Ludmila; Valuţa, Ana; Chiriac, Tatiana; Codreanu, Svetlana; Miscu, Vera; Cojocari, Angela
    There wasstudied the impact ofantioxidant complex from microalga Porphyridium cruentum biomass on the antioxidant activityof vegetable oilsand their oxidation process. The antioxidant complex was obtained by extracting in 96% ethylalcohol. Antioxidant assay using the radical1,1-diphenyl-2-picryl-hydrazil (DPPH) revealed an increase of the antioxidant activity of oils supplemented with microalgal antioxidant complex. There was determineda decrease (up to 40% for olive oil) in fatty acid oxidation for vegetable oils with microalgal antioxidant extract.

    STUDIUL ACŢIUNII COMPUŞILOR COORDINATIVI NOI AI Fe(III) ŞI AI Cr(III) ASUPRA PROCESULUI DE ACUMULARE A UNOR PRINCIPII BIOACTIVE ÎN BIOMASA DE SPIRULINĂ
    (CEP USM, 2009) Ciumac, Daniela; Zosim, Liliana; Chiriac, Tatiana; Prodius, Denis; Olan, Olga; Popa, Veaceslav; Sadovnic, Daniela; Iaţco, Iulia; Cordeleanu, Cornel; Oni, Veronica
    The study of stimulative effect of some Fe(III) heterotrinuclear clusters and Cr(III) coordinative compouds on pep-tides and proteins content in Spirulina platensis biomasshas been carried out.The protein content decreases with the growth of concentrations in the case of utilization of all coordinative com-pounds tested. The peptides content increases in the limits of 5,00-50,00 mg/l for Fe(III) coordinative compounds and 10,00-40,00 mg/l for Cr(III) coordinative compounds.
