dc.description Lucrare brevetată sau în curs de brevetare: Cerere de brevet nr. a 2022 0059 din 29.12.2022. en_US
dc.description.abstract Se propune un procedeu nou de obținere a preparatului proteoglicanic din biomasa reziduală de Arthrospira platensis. Biomasa se amestecă cu alcool etilic de 96% (1:10), se plasează la baia cu apă la +45˚C 30 min cu agitare periodică, se centrifughează. Biomasa restantă se amestecă cu apă distilată (1:3 v/v), se supune sonicării 5 min, se încălzește la +45˚C 30 min sau se autoclavează la +115°C 30 min, se centrifughează. Preparatul conține 661±2.30-733±1.55 mg/l polizaharide sulfatate, 20.66±0.12- 26.50±0.06% S.U. proteine, 23.69±0.73-20.71±0.42% S.U. carbohidrați, posedă activitate SOD de 54.68±2.82-38.41±0.42 U/mg proteină. en_US
dc.description.abstract A new process for obtaining the proteoglycan preparation from the grinding residual biomass of Arthrospira platensis is proposed. The biomass is mixed with 96% ethyl alcohol (1:10), placed in a water bath at +45˚C for 30 min with periodic stirring and centrifuged. Then the remaining biomass is mixed with distilled water (1:3 v/v), sonicated for 5 min, heated at +45˚C for 30 min or autoclaved at +115°C for 30 min, centrifuged. The obtained preparation contains 661±2.30-733±1.55 mg/L sulphated polysaccharides, 20.66±0.12-26.50±0.06% S.U. proteins, 23.69±0.73-20.71±0.42%U.S. carbohydrates, possess SOD activity of 54.68±2.82-38.41±0.42 U/mg protein. en_US
