Method for preparing at least one organic compound (I) with at least 3 C atoms or at least two C and at least one N by fermentation comprises: (a) milling a starch source (S) to form a milled product (MP) that includes at least part of the non-starch containing solid components (X) of (S); (b) suspending (MP) in aqueous liquid to form a suspension; (c) hydrolysis of the starch components of MP by liquefaction and optionally subsequent saccharification; to produce an aqueous medium (M); and (d) using (M) in a fermentation for culturing a microorganism (MO) capable of overproducing (I). Method for preparing at least one organic compound (I) with at least 3 C atoms or at least two C and at least one N by fermentation comprises: (a) milling a starch source (S) to form a milled product (MP) that includes at least part of the non-starch containing solid components (X) of (S); (b) suspending (MP) in aqueous liquid to form a suspension of at least 45 wt.% dry matter content; (c) hydrolysis of the starch components of MP by liquefaction and optionally subsequent saccharification; to produce an aqueous medium (M) that contains the hydrolyzed starch components and at least some of (X); and (d) using (M) in a fermentation for culturing a microorganism (MO) capable of overproducing (I). In step (c), the suspension from step (b) is heated to above the gelatinization temperature of the starch component in MP by introduction of steam. |
