Dissimilatory nitrate reduction by liquid membrane encapsulated cell-free extracts and whole cells of Micrococcus denitrificans.

The combination of Sephadex G-15 and ion-exchange resin columns allows one-step desalting and separation of cellodextrins using water as the sole eluent. The column apparatus described in this paper has the potential of producing up to 3 g cellodextrins in one day. In addition, the columns described are stable and do not require repacking or regeneration after each run. Hence the potential exists for scaling up this system for even greater production of cellodextrins if need be.
