Wastewater from the demineralization of cheese whey for cost‑efcient cultivation of spirulina

Popis výsledku v původním jazyce

Worldwide, there is growing interest in achieving a meaningful use of natural resources, as epitomized in this work, which demonstrates the use of saline wastewater (WW) from the demineralization of cheese whey as the main component of a medium for cultivation of spirulina (Limnospira maxima). Based on Zarrouk medium and the fundamental composition of spirulina biomass, a novel cultivation medium for photoautotrophic cultivation of spirulina was developed. The wastewater medium (WWM) consisted of WW supplemented with NaHCO3, urea, K2HPO4, and FeSO4. The suitability of WWM was evaluated by comparison of spirulina growth in laboratory scale tubular or gas-lift photobioreactors in WWM and Zarrouk medium (ZM). The maximum biomass productivity of 0.36 g L−1 day−1 was achieved in WWM, compared with 0.24 g L−1 day−1 in ZM. The cost of WWM was less than 50% of the cost of ZM.
