The invention relates to the combination of the TLG1 glucoamylase from Thermomyces lanuginoses with: (i) the SFA1 alpha-amylase from Saccharomycopsis fibuligera; and/or (ii) the LKA alpha-amylase. The enzyme combinations may be expressed in a host cell (e.g. in Saccharomyces cerevisiae) or provided as an enzyme composition. Methods for making the enzyme combinations of the invention are provided. The invention also relates to a yeast strain which exhibits amylolytic activity and promising fermentative abilities. Processes for producing a fermentation product (in particular alcohol) from starch-containing material are described.
