Downstream processing of biobased succinic acid (5)

Approach V: Sorption-Based SA Purification
(Davison et al. Appl. Biochem. Biotech, Vol. 113-116,653 (2004))

Key points for the process
–Key desirable properties for an ideal sorbent
--High capacity: >0.06 g SA/ g resin at moderate concentrations (1-5 g/l)
--Complete low-cost stable regenerability: 70% recovery using hot water and >95% using a modified extraction combining acid and hot washes
--Specificity for the product: a recovered concentration> 100 g/L

What about the feasibility for commercialization?
