Fed-batch cultivation of Arthrospira (Spirulina) platensis: Potassium nitrate and ammonium chloride as simultaneous nitrogen sources

Arthrospiraplatensis was cultivated in minitanks at 13klux, using a mixture of KNO3 and NH4Cl as nitrogen source. Fed-batch daily supply of NH4Cl at exponentially-increasing feeding rate allowed preventing ammonia toxicity and nitrogen deficiency, providing high maximum cell concentration (Xm) and h...
