Notizen:
As part of a program to investigate the use of biological nitrogen fixation for fertilizer ammonia production, an investigation into the immobilization of the aerobic, nitrogen-fixing bacterium, Azotobacter vinelandii was undertaken. Immobilization was accomplished by adsorption onto an anionic exchange cellulose (Cellex E)with loadings as high as 1011cells/g resin. Immobilized cell preparations were tested under both batch and continuous-flow conditions. Nitrogenase activity as high as 4200 nmol/min g resin were observed as measured by the acetylene reduction assay. Immobilized cells retained their activity for as long as 177 hr in a continuous-flow reactor. Activity loss appeared to be related to the development of a variant strain.
