Pilot scale semicontinuous production of Spirulina biomass in southern Brazil

We evaluated the feasibility of the pilot scale production of Spirulina strain LEB-18 in southern Brazil and assessed the quality of biomass produced in relation to its kinetics characteristic, nutritional value, heavy metal content and microbial content. The maximum mean biomass concentration was 1...

Zusammenfassung:	We evaluated the feasibility of the pilot scale production of Spirulina strain LEB-18 in southern Brazil and assessed the quality of biomass produced in relation to its kinetics characteristic, nutritional value, heavy metal content and microbial content. The maximum mean biomass concentration was 1.24 g L−1 and the maximum productivity was 69.16 g m−2 d−1. The biomass showed 84.0% digestibility, 86.0% (w/w) protein and 3.3% (w/w) lipid content. Analyses showed that the concentration (mg kg−1) of heavy metals (As, 0.28±0.01; Cd,
