- Abstract
- Cyanobacteria play a major role as direct producers of biofuels, such as ethanol and butanol, with the aid of genetic engineering. However, development of a new harvesting-technology is essential to achieve economic viability of biofuel production from cyanobacteria. In this study, we demonstrated the feasibility of harvesting the unicellular cyanobacterium Synechocystis sp. PCC 6803 using pre-made filamentous fungal pellets and investigated key factors affecting efficiency of harvest, including fungal strain, pellet quantity (number of pellets), initial pH, and organic carbon source. Synechocystis sp. PCC 6803 cells attached to Aspergillus oryzae pellets, indicating that this fungal pellet had a desirable harvesting effect, while Rhizopus oryzae pellets had no effect on harvesting. Increasing pellet quantity and adding organic carbon sources, such as glucose and xylose, improved the harvesting efficiency of Aspergillus oryzae pellet; efficiency was not affected by the initial pH.
