HCID 222656L-Malic Acid

Procedure

Cell mass grown according to example C is suspended in 16 liters of a 240 g/l solution containing fumaric acid (neutralized with NH4OH and NaOH in the molar ratio of 2 to 1). The concentration of the cell mass in the fumaric acid solution amounts to 6 g/l (calculated as dry mass). After 24 hours of incubation, 234 g of L-malic acid per liter of fermentation liquid is produced.

Workup

  1. dry with materialThe concentration of the cell mass in the fumaric acid solution amounts to 6 g/l (calculated as dry mass)
