Item ELABORAREA SCHEMEI TEHNOLOGICE DE OBTINERE A UNOR PRINCIPII BIOACTIVE DIN BIOMASA DE ALGE CIANOFITE(CEP USM, 2014) Bulimaga, Valentina; Zosim, Liliana; Pisova, Maria; Şalaru, Vasile; Ţurcanu, Olga; Trofim, AlinaThe technological scheme of obtaining of phycoerythrin, phycocyanin, microcystins, endo– and exopolysaccharides from the blue green algae biomass in a single technological process has been developed and a sorbent for the separation of microcystins and phycobiliproteins have been proposed.Item PRODUCTIVITATEA MICROALGEI VERZI DUNALIELLA SALINA LA CULTIVARE ÎN PREZENŢA UNOR COMPUŞI AI Ge(IV(CEP USM, 2013-09-26) Bivol, Cezara; Zosim, Liliana; Elenciuc, Daniela; Djur, Svetlana; Olan, Olga; Batîr, LudmilaItem INFLUENŢA CITRATULUI DE FIER ŞI INTENSITĂŢII LUMINII ASUPRA CONŢINUTULUI DE CAROTENOIZI ŞI FIER ÎN BIOMASA DE SPIRULINĂ(CEP USM, 2013-09-26) Bulimaga, Valentina; Zosim, Liliana; Pisov, MariaItem EFECTUL UNOR COMPUŞI COORDINATIVI AI CU(II) ASUPRA CONŢINUTULUI DE GLICEROL ÎN BIOMASA MICROALGEI VERZI D. SALINA LA VARIEREA UNOR PARAMETRI FIZICI DE CULTIVARE(CEP USM, 2014) Bivol, Cezara; Zosim, Liliana; Elenciuc, Daniela; Batîr, Ludmila; Djur, Svetlana; Olan, OlgaItem 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 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, VeronicaThe 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.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 ELABORAREA PROCEDEELOR DE OBŢINERE A BIOMASEI DE SPIRULINĂ CU CONŢINUT ÎNALT DE FIER CA PARTE COMPONENTĂ EFECTIVĂ(CEP USM, 2007) Zosim, LilianaSome procedures of the iron fortified spirulina biomass have been elaborated. These pro cedures provide a high iron content în biomass – 1,01-1,2% and can be used to obtain antianemic products.
