    STUDIUL ACUMULĂRII CUPRULUI LA CULTIVAREA CIANOBACTERIEI SPIRULINA PLATENSIS ÎN PREZENŢA COMPUŞILOR COORDINATIVI AI Cu(II)
    (CEP USM, 2009) Rudic, Valeriu; Batîr, Ludmila; Bulimaga, Valentina; Zosim, Liliana; Elenciuc, Daniela; Gulea, Aurelian; Ţapcov, Victor
    The acumulation of copper in biomass of cyanobacteria Spirulina platensis CNM - CB – 02 at the cultivation in the presence of coordination compounds of Cu (II) has been determined. Bioaccumulation of copper depends on the nature of ligands of the compounds. It was established that compounds [CuL2(Sfz)3H2O] and [Cu(L-2H)] contribute to the increasing of copper content in the biomass of spirulina in 2,94 – 3,42 times compared to the reference sample.

    STUDIUL INFLUENŢEI COMPUŞILOR COORDINATIVI AI Cu(II) ASUPRA PRODUCTIVITĂŢII CIANOBACTERIEI SPIRULINA PLATENSIS
    (CEP USM, 2009) Rudic, Valeriu; Batîr, Ludmila; Gulea, Aurelian; Ţapcov, Victor
    The productivity of cyanobacteria Spirulina platensisat the cultivation in presence of coordinative compound of Cu(II) havs been determined. The spirulina productivity depends on coordination compounds nature and concentrations. Coordinative compounds: [Cu(L1-H)H2O(NO3)], CuL32(NO3)2 and CuL(NO3)2 had the most favorable effect for biomass accumulation

    PROCEDEE DE OBŢINERE A BIOMASEI DE SPIRULINĂ CU CONŢINUT SPORIT DE CUPRU LEGAT ORGANIC
    (Agentia de Stat pentru Proprietatea Intelectuala a Republicii Moldova (AGEPI), 2013) Zosim, Liliana; Ţapcov, Victor; Gulea, Aurelian; Batîr, Ludmila; Rudic, Valeriu
    În prezentul articol este descrisă elaborarea a două procedee de obţinere a biomasei de spirulină cu conţinut sporit de cupru legat cu compuşi organici componenţi ai biomasei (proteine, oligopeptide, aminoacizi, lipide, glucide), utilizându-se în calitate de reglatori compuşii coordinativi ai Cu(II).
