Abstract
The invention relates to a method for producing at least one organic compound comprising at least 3 C-atoms or at least 2 C-atoms and at least 1 N-atom by fermentation. Said method comprises the following steps: i) a starch source is ground in order to obtain a grinding material which contains at least one part of the non-starch containing solid components of the starch source; ii) the grinding material is suspended in an aqueous liquid in an amount such that the dry mass content in the suspension is at least 45 wt. %, iii) the starch component is hydrolysed in the grinding material by liquefying and optionally, subsequently, sweetening, in order to obtain an aqueous medium M, which contains the hydrolysed starch components and at least one part of the non-starch containing solid components of the starch source, is obtained; and iv) the aqueous substance M obtained in step iii) is used for fermentation in order to cultivate a micro-organism which is capable of over-producing the organic compound; the suspension obtained in step ii) is heated in step iii) by introducing vapor into the suspension, in order to obtain temperatures greater than the pasting temperature of the starch obtained in the grinding materials.
