Application of recent developments in filtration separations have been applied to separation of biopolymers from fermentation broths. More economical production of biopolymers near the site of use would be especially attractive for use in micellar flood programs for enhanced oil recovery. Solutions of the organisms Sclerotium rolfsii producing scleroglucans were used for the tests because the organisms are genetically more stable than the organisms that produce xanthan gums and because their more acid broths are less apt to become contaminated. Three types of filtration, axial filtration, pleated ultrafiltration module, and microscreens were tested on the broth. Filtration results are reported for broths with various preparation histories. An economic comparison is presented for processing of a ton of biopolymer per day, and the microscreening process is shown to be the most efficient, but a polishing step would have to be added.
