Immobilized yeast
Witryna1 dzień temu · The immobilized yeast with carrier had a better effect than yeast pellets for the remediation. The presence of carrier material provided more attachable sites for yeast, improved the stability of PRB material and facilitated the removal of Cd (Chen et al., 2012). Comparing the tests IMEK 6, IMEK 8, and IMEK 9, it can be found that the … Witryna1 sty 2004 · A one-stage continuous primary beer fermentation with immobilized brewing yeast was studied. The objective of the work was to optimize the operational conditions (aeration and temperature) in terms of volumetric productivity and organoleptic quality of green beer. The system consisted of an internal-loop airlift reactor and a carrier …
