Undoubtedly, HYVOLUTION has significantly contributed to the
improved understanding of the two-stage process including photofermentation
stage. Research presently being carried out by
various research groups is aimed at improving the performance of
that stage and optimizing the photobioreactor design, so that reductions
in the operation and investment costs are possible in short
to medium term. Work is also conducted on ways to decrease the
consumption of chemicals in both fermentation stages, aiming at
further reduction in the operating cost.
