FIELD: chemistry.
SUBSTANCE: group of inventions relates to succinic acid-producing mutant microorganism, which is able to apply simultaneously saccharose and glycerine as carbon sources. Mutant microorganism is obtained by weakening of mechanism of saccharose-mediated catabolite repression of glycerol by removal of gene, which codes fructosephosphotransferase, or by introduction of gene, which codes glycerolkinase. Mutant microorganism is selected from the group, which consists of Mannheimia sp., Actinobacillus sp. and Anaerobiospirillum sp. Also claimed is method of obtaining mutant microorganism and versions of method of obtaining succinic acid with application of claimed microorganism.
EFFECT: group of inventions provides obtaining succinic acid with high output 1,54 mol/mol.
