Abstract: The present invention is directed to an industrial fermentation process for cultivating a Bacillus cell in a chemically defined fermentation medium and a method for producing a protein of inter-est comprising the steps of providing a chemically defined fermentation medium, inoculating the fermentation medium with a Bacillus cell comprising a gene encoding a protein of interest, cultivating the Bacillus cell in the fermentation medium under conditions conductive for the growth of the Bacillus cell and the expression of the protein of interest, wherein the cultivation of the Bacillus cell comprises the addition of one or more feed solutions comprising one or more chemically defined carbon sources and magnesium ions to the fermentation medium.

Abstract: The present invention provides a modified Bacillus cell for the production of a compound of interest, wherein the Bacillus cell comprises a genetic modification that leads to decreased production of enzymes with lipase and/or esterase activity. The use of compounds of interest produced with said improved Bacillus host cells reduces the formation of malodour and/or off-flavour when used for applications such as washing or cleaning or as feed or food additives.
