Comparative analysis of the fermentation performance of high-quality milk beer strains (Kluyveromyces marxianus) and optimisation of medium formula for high-density fermentation
Milk beer is a new type of dairy beverage in China and increasingly popular with consumers. The strain FXJ1 isolated in our laboratory was an excellent strain for the production of milk beer with alcohol content of 0.48%. Our research verified that the strain FXJ1 was superior to the commercial strain MJ for milk beer production and got the optimal medium formula (67.37 g/L sucrose, 29.7 g/L yeast extract, 15.61 g/L corn steep liquor, 4.13 g/L KH 2 PO 4 and 0.3 g/L MgSO 4 ) which allowed the biomass production of strain FXJ1 to achieve 8.88 ± 0.08 g/L and increase 2.94-fold as compared with yeast extract peptone dextrose base medium.
