Abstract: | Summary Whole filaments of the N2-fixing cyanobacterium Anabaena ATCC 27893 have been immobilized by entrapment in calcium alginate gel beads. In a continuous flow fluidized bed reactor sustained photosynthesis, N2-fixation, and ammonia production have been achieved over a 130 hour period, the longest tested. |
