Erratum to: Outdoor open thin-layer microalgal photobioreactor: potential productivity

Abstract

Figure 1 shown in the article does not represent real timecourse of algal growth in the photobioreactor during one fedbatch growth cycle. It was constructed as an ideal growth curve to estimate the maximum productivity using selected data obtained during clear summer days. Not included in the curve is the lower growth rate of the culture at the beginning of the curve. This would prolong the length of the cycle up to 12– 14 days and decreases the average daily net areal productivity in course of the growth cycle to about 29 g m d. Still, under ideal climate and growth conditions, yields of 80–100 t of dried Chlorella biomass per 1 ha area could be theoretically reached for a 300-day cultivation season. One of the major goals of algal biotechnology is to prove experimentally that such high biomass yields can be achieved in Chlorella strains with high starch content (50 % in biomass).
