    COORDINATION COMPOUNDS AND CHEMICAL COMPOSITIONS WITH ANTIOXIDANT PROPERTIES
    (2023) Bulhac, Ion; Ștefîrță, Anastasia; Brînză, Lilia; Coropceanu, Eduard; Voloșciuc, Leonid; Cocu, Maria
    In the paper are presented the main results that argue the antioxidant effect of BACC and some chemical compositions on plants. The anti-stress action of the new preparations - Conimid, Difecoden, Fludisec, Polyel, Galmet and Thiogalmet, is provided by increasing the antioxidant protection capacity due to the decrease of the content of malondialdehyde, intensification of the activity of antioxidant enzymes, increase in the content of non-enzymatic antioxidants with low molecular mass. The possibilities of optimizing the resistance of plants to oxidative stress, caused by drought, and stabilization of plant productivity are promising. The biological performance of plants pre-treated with BACC and antioxidant preparations are more fully realized under both optimal moisture and moderate drought conditions.

    THE INFLUENCE OF SOME Ca(II) AND BA(II) WITH Co(II) COMPOUNDS ON THE PRODUCTIVITY OF THE CYANOBACTERIA SPIRULINA PLATENSIS
    (2023) Nedbaliuc, Boris; Coropceanu, Eduard; Ciobanu, Eugeniu; Grigorcea, Sofia; Ureche, Dumitru; BrÎınză, Lilia
    The article includes experimental results related to the productivity of the Spirulina platensis (Nordst.) Geitl - CALU - 835 strain, which was cultivated for 8 days on modified nutrient media supplemented with two coordination compound containing Ca and Ba. A greater amount of biomass was recorded when growing spirulina on the Zarrouk culture medium supplemented with these coordination compound in a concentration of 5 mg/L, accumulating a fresh biomass of about 13,3 g/L and 12,8 g/L, respectively, or about 14,5% and 9,9% higher than that accumulated by the witness.
