Mass cultivation of microalgae for commercial applications suffers from poor productivities when measured against laboratory results or theoretical projections. In an effort to reduce this gap it was discovered that addition of eucalyptus kraft black liquor (BL) enhanced biomass productivity in outdoor cultures of Spirulina by increasing growth rate by 38% and biomass yield by 43%. BL treatment resulted in elevation of nitrogen assimilating enzyme activities and efficiency of phosphate utilization. Analyses of forenoon and afternoon oxygen production rates (OPRs) indicated higher photosynthetic and respiratory activity in BL‐treated cultures compared to untreated cultures.
