Abstract

Enzymatic membrane reactor (EMR) is well established and accepted as one of the most recent and advanced technologies in the biotechnology area. Many patents and scientific papers dealing with the membrane application are only focusing on the production of CDs but inattentive on the membrane performance and configuration. As a result the membrane fouling is a crucial problem that hinders the wide application of membrane process. In addition, most of the previous studies applied corn and potato starch as a raw material to produce CDs but not much study has been carried out in application of tapioca starch as a raw material. Even though its viscosity is greater than other starches, it will produce higher yield in CDs production compared to other starches. In fact, there is still little agreement on the contribution of tapioca starch in CDs production to membrane fouling. As a matter of fact the rate and extent of contribution by the size distribution, concentration and structural variation of foulants to the fouling are also not well understood. Additionally, none of the previous journals employed a membrane cleaning system in their production of CDs.
