As photosynthetic efficiencies are relatively high at irradiation levels of
<500 mu mol m(-2) s(-1), photosynthetic productivity could be increased by
redistributing strong light over a larger photo-receiving area using conic
al, helical, tubular photobioreactors (HTP). When Chlorella were exposed to
light irradiation of 980 mu mol m(-2) s(-1), the ratio of productivities w
as 1.00:1.13:1.23:1.66 for conical HTPs with cone angles of 180 degrees (fl
at type), 120 degrees, 90 degrees, and 60 degrees, respectively. This sugge
sts that photo-redistribution technology is a highly effective and convenie
nt approach for increasing the photosynthetic productivity of microalgae. (
