Many of the demands in the production of microalgae at a technical scale cannot presently be met by state-of-the-art cultivation technologies based on suspensions. Immobilized cultivation using porous substrate bioreactors (PSBRs) is characterized by a reduction of liquid reaction volumes by several orders of magnitude and has solved several volume-related problems. Recently, PSBRs demonstrated potential for both established and novel applications in microalgal biotechnology, and first insights into biophysical processes have provided an understanding of the benefits of PSBR biofilm cultivation. Further efforts should primarily focus on scale-up and engineering challenges in this emerging field and, additionally, provide experience in the long-term operation of bioreactors. The results may contribute to assessing the technical and economic potential of PSBR cultivation.<\/p>\n
Trends
\nPorous substrate bioreactors (PSBRs) grow microalgae immobilized in dense biofilm cultures. They solve some substantial problems related to the high liquid volume and low culture densities attributed to state-of-the-art cultivation methods in microalgal biotechnology.<\/p>\n
Recently, proof of principle for several established and innovative products and applications in algal biotechnology and environmental biotechnology has been demonstrated. Scalability was demonstrated at a small pilot scale.<\/p>\n
The first insights into the biophysical processes occurring within PSBR biofilms have provided a basic understanding of some advantages of PSBR cultivation.<\/p>\n
Areal productivities compare favorably with highly productive closed suspension photobioreactors. The simple construction and low energy demands of PSBRs may indicate the significant economic potential of this novel microalgal cultivation system.<\/p>\n","protected":false},"excerpt":{"rendered":"
