| 摘要 |
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: al) 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; a2) the grinding material is suspended in an aqueous liquid and said grinding material contained in the aqueous liquid is liquefied in the presence of at least one enzyme which liquefies starch, an aqueous substance which contains dextrin (1), which contains at least one part of the non-starch containing solid components of the starch source, is obtained; and b) the aqueous substance which contains dextrin (1) is used in fermentation for cultivating a micro-organism which is capable of over-producing the organic compounds; enzymes, which hydrolyse the dextrin into monosaccharides, are not added or are added in an amount of less than 0.001 wt. %, in relation to the total weight of the used starch source. |
