abstract = {An increasing number of investors is looking at algae as a
viable source of biofuels, beside cultivation for
human/animal feeding or to extract high-value chemicals and
pharmaceuticals. However, present biomass productivities are
far below theoretical estimations implying that a large part
of the available photosynthetically active radiation is not
used in photosynthesis. Light utilisation inefficiency and
rapid light attenuation within a mass culture due to high
pigment optical density of wild type strains have been
proposed as major limiting factors reducing solar-to-biomass
conversion efficiency. Analysis of growth yields of mutants
with reduced light-harvesting antennae and/or reduced
overall pigment concentration per cell, generated by either
mutagenesis or genetic engineering, could help understanding
limiting factors for biomass accumulation in
photobioreactor. Meanwhile, studies on photo-acclimation can
provide additional information on the average status of
algal cells in a photobioreactor to be used in
modelling-based predictions. Identifying limiting factors in
solar-to-biomass conversion efficiency is the first step for
planning strategies of genetic improvement and domestication
of algae to finally fill the gap between theoretical and
industrial photosynthetic productivity.},
