Abstract
Potential benefits for anaerobic digestion processes of hydrolysing intact yeast cells in malt whisky distillery pot ale were investigated. Several yeast lytic enzymes, that can dissolve glucan and mannoprotein components of the cell wall, were effective. For example, anaerobic digestion of pot ale pre-treated with yeast lytic enzymes showed COD reductions of 87%, compared with only 13% without enzymes. It was therefore established that pre-hydrolysis of intact yeast cells in distillery pot ale was very beneficial for efficient anaerobic treatment of such residues for biogas production.
