A novel configuration of photobioreactor
is described in which filaments of alginate containing
immobilized cells of a leaky mutant of Dunaliella
parva are wound round a central light well which is
located within a glass outer chamber so that a liquid
medium is caused to flow in the annular space between
the outside chamber and the alginate filaments.
Glycerol production by D. parva was maintained for
700 h and the highest concentration of glycerol
attained was approx. 12 mg l-1
