Item 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, VictorThe 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.Item MODIFICAREA COMPONENŢEI CALITATIVE A PROTEINELOR LA CIANOBACTERIA SPIRULINA PLATENSIS CULTIVATĂ ÎN PREZENŢA UNOR COMPUŞI COORDINATIVI AI CR(III)(CEP USM, 2008) Rudic, Valeriu; Bulimaga, Valentina; Ciumac, Daniela; Zosim, Liliana; Chiriac, Tatiana; Efremova, NadejdaSDS-electrophoresis of polypeptide chains of total protein fraction obtained from Spirulina cultivated in the presence of Cr(III) coordination compounds have been carried out. New bands with apparent molecular mass 60, 4 kDa and 66, 7 kDa have been detected in the presence of Cr(III) coordination compounds.Item TEHNOLOGIA OBŢINERII ÎN BAZA BIOMASEI DE SPIRULINĂ A REMEDIULUI MEDICAMENTOS FERRIBIOR ŞI STUDIUL ACŢIUNII LUI ANTIANEMICE(CEP USM, 2008) Rudic, Valeriu; Gudumac, Valentin; Zosim, Liliana; Chiriac, Tatiana; Bulimaga, Valentina; Ciumac, DanielaThe technological scheme of obtaining of the preparation Ferribior with high content of organic iron (0,04-0,05%)and other bioactive substances: immunoactive amino acids (71% from free total amino acids and 70,57% from conjugated amino acids) and polysaccharides (6-7%) from spirulina biomass has been elaborated. The capacity of Ferribior to reestablish the plasmatic iron and zinc level and to stimulate hemathopoesis at experimental rats has been demonstrated.Item COMPONENŢA AMINOACIDĂ A OLIGOPEPTIDELOR ŞI AMINOACIZILOR LIBERI DIN BIOMASA DE SPIRULINĂ CULTIVATĂ ÎN PREZENŢA UNOR COMPUŞI COORDINATIVI AI Fe(III) Ş I Zn(II)(CEP USM, 2007) Rudic, Valeriu; Chiriac, Tatiana; Bulimaga, Valentina; Zosim, Liliana; Turtă, Constantin; Prodius, DenisAmino acid composition of oligopeptids and amino acids fractions in spirulina biomass cultivated in the presence of some coordinative compounds of Fe(III) and Zn(II) has been determined. High content of essential and especially immunoactive amino acids was pointed out in this study.Item EFECTUL STIMULATOR AL COMPUŞILOR COORDINATIVI AI CROMULUI(III) ASUPRA PRODUCTIVITĂŢII SPIRULINEI(CEP USM, 2007) Rudic, Valeriu; Gulea, Aurelian; Bulimaga, Valentina; Ciumac, Daniela; Ciornea, Valeriu; Zosim, Liliana; Popa, AlexeiThe action of some coordinative compounds of Cr(III) on Spirulina strain growth and development has been studied. High stimulation action of K2[Cr(NTA)(C2O4)(H2O)]·2H2O and [K2Cr2(SO4)4]·12H2O on Spirulina productivity has been established.Item STUDIUL UNOR PARAMETRI DE CULTIVARE A MICROALGEI VERZI DUNALIELLA SALINA LA CREŞTEREA PE LICHID CULTURAL REZULTAT DIN PRODUCEREA BIOMASEI DE SPIRULINĂ(CEP USM, 2007) Bivol, Cezara; Rudic, ValeriuAfter cultivating blue-green algae Spirulina platensis remains its cultural liquid actually becomes a biotechnological waste. This liquid contains important biologically active substances and might be used as culture medium for other microalgae. An appropriate representative is the green microalgae Dunaliella salina – a valuable source of β-carotene. The medium D. salina optimization has been carried out. The major cultural factors of influence (salinity, light intensity) on Dunaliella salina productivity have been determined.Item STUDIUL INFLUENŢEI COMPUŞILOR COORDINATIVI AI Cu(II) ASUPRA PRODUCTIVITĂŢII CIANOBACTERIEI SPIRULINA PLATENSIS(CEP USM, 2009) Rudic, Valeriu; Batîr, Ludmila; Gulea, Aurelian; Ţapcov, VictorThe 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
