Manufacture of gluconic acid: A review towards process

The recovery process may vary from type of products like gluconic acid, glucono-δ-lactone, calcium gluconate and sodium gluconate. Currently gluconic acid produced by batch submerged-fermentation using A. niger and Zymomonas mobilis from carbon source glucose syrup of 70 Brix strength.

It is metabolized to glucose; one gram of D-(+)-Glucono-1,5-lactone yields roughly the same amount of metabolicenergy as one gram of sugar. Upon addition to water, GDL is partially hydrolysed to gluconic acid, with the balance between the lactone form and the acid form established as a chemical equilibrium.

Like glucose, it cyclizes in solution, in this case to form an ester (glucono-δ-lactone) rather than a hemiacetal. Gluconic acid widely exists in nature, especially in fruits and in sucrose-containing substances such as honey. Early methods of synthesizing gluconic acid from glucose included hypobromite oxidation and alkaline hydrolysis.
