Method of producing normal butyric acid by fermentation from a sugar substrate in the presence of at least one strain of clostridium species.

摘要

PRODUCTION IN A reaction AREA OF A MIXTURE OF ORGANIC ACIDS OR SALTS FOR, CONTAINING more of n-butyric acid or the corresponding salt, fermenting a medium INITIAL reaction CONTAINING A SWEETENED SUBSTRATE, IN THE PRESENCE OF A strain belonging to Clostridium species. PRODUCTION STAGES: A) the strain in substrate supplied with an initial concentration between 1 and 80 g of substrate per liter of medium INITIAL reaction; B) GETS DOWN IN SUBSTRATE CONCENTRATION 20% of its initial value and to a value between 0 and 30 G of substrate per liter of medium INITIAL reaction; C) the strain in substrate fed a between 0.01 and 25 g per liter of reaction INITIAL AMOUNT AND TIME, THAT Prara feeding time as equal concentration is maximum 80 g / l reaction medium INITIAL; YD) RECOVER THE BLEND SALES acids or so produced.
