Investigations were carried out into the capacity of waste brewery yeast Saccharomyces uvarum for biosorption of magnesium originated from a solution of dehydrated salt of magnesium chloride, depending on the number of cells and diferent pH of the suspension during 6 hours. The concentration of MgCl2·6H2O in the solution was adjusted so as to maintain a stable content of magnesium as expressed per...
The study aimed at determining which part of magnesium permanently bound with bakers yeasts S. cerevisiae No. 102 during batch culture in control (YPD) and experimental medium (YPD with the addition of magnesium) remains in the cell wall and which undergoes intracellular bio-accumulation. The experimental media were supplemented with the amount of MgCl2*6H2O providing 1.25 g/dm3 content of Mg2+ ions...
In this research, the No. 1 Sacharomyces cerevisiae brewery yeast strain capacity to bind the Mg2+ ions was studied. The yeast were cultivated in dynamic conditions in the YPD medium enriched with the MgSO4 · 7H2O or MgCl2 · 6H 2O magnesium salts. The salts were being added in such an amount, to make the sheer element content in the medium amounting to 0.25 g · dm-3; 0.5 g · dm-3 or 1.25 g · dm-3...
Badano zdolność wiązania magnezu przez przemysłowy szczep drożdży piekarskich podczas hodowli stacjonarnej na podłożu YPD, wzbogaconym w jony magnezu w ilości 0,25, 0,5 i 1,25 Mg2+/dm3. Jony magnezu pochodziły z dwóch soli: MgS04 x 7H20 lub MgCl2 x 6H20. Sole magnezu dodawano do podłoży doświadczalnych na początku hodowli lub pod koniec logarytmicznej fazy wzrostu drożdży. Równolegle prowadzono hodowlę...
