    Extracts derived from spirulina cultivated on media with Cu and CuO nanoparticles as active agents for triticale seed priming
    (CEP USM, 2024) Cepoi, Liliana; Rudi, Ludmila; Chiriac, Tatiana; Zosim, Liliana; Iațco, Iulia; Rudic, Valeriu
    This study investigates the effects of seed priming in triticale using extracts from Arthrospira platensis cultivated with copper nanoparticles (CuNP) and copper oxide nanoparticles (CuONP). Results demonstrate significant increases in chlorophyll, carotenoid, and phenolic content, alongside enhanced antioxidant activity in the leaves. Notably, the treatment with nanoparticle-enriched extracts reduced malondialdehyde (MDA) levels, indicating a protective effect against oxidative stress. The findings suggest that spirulina-based extracts, even with the addition of nanoparticles, can enhance crop health, offering a sustainable approach to agriculture.

    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; Iațco, Iulia; Cordeleanu, Cornel; Doni, Veronica
    The study of stimulative effect of some Fe(III) heterotrinuclear clusters and Cr(III) coordinative compouds on peptides and proteins content in Spirulina platensis biomass has been carried out.The protein content decreases with the growth of concentrations in the case of utilization of all coordinative compounds 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.
