Summary

Mass cultivation of Spirulina for commercial application suffers from poor productivity when measured against laboratory results or theoretical projections. Wider applications of algal products require that this gap be reduced. Addition of eucalyptus kraft black liquor at a maximum of 0.1% to Spirulina cultures enhanced biomass productivity by at least 40%. The factors enhancing Spirulina biomass productivity were insoluble at low pH, of low molecular mass and stable to high temperature. Single addition of kraft black liquor in outdoor continuous cultures afforded sustained enhancement in biomass productivity for at least eight weeks.
