dc.description.abstract Procedeul, conform invenţiei, prevede utilizarea biomasei de levuri din deşeurile industriei de bere (30 g) care se amestecă cu 30 ml soluţie tampon fosfat de sodiu (raport 1:1), apoi se supune autolizei la +37°C sau +45°C timp de 8 ore, cu agitare periodică, centrifugarea, prelucrarea sedimentelor cu soluţie 1N NaOH (raport 1:5) la temperatura de +80±5°C timp de 2 ore, apoi se efectuează centrifugarea la 3500 rot./min timp de 15 min şi supernatantele alcaline obţinute se sedimentează cu alcool etilic 96% în volum 1:2. Procedeul permite obţinerea cu 7-16% mai multe manoproteine comparativ cu varianta martor. en_US
dc.description.abstract The process according to the invention includes the use of brewer's yeast biomass (30 g) which is mixed with 30 ml of sodium phosphate buffer (1:1 ratio) then subjected to autolysis at +37°C or +45°C for 8 hours, with periodic stirring, then centrifugation and the process of remaining the sediments with 1N NaOH solution (1:5 ratio) at +80±5°C for 2 hours,, centrifugation at 3500 rpm. for 15 minutes, the obtained alkaline supernatants were sedimented with 96% ethyl alcohol in a volume of 1:2. The process allows obtaining 7-16% more mannoproteins compared to the control variant. en_US
