Description Spirulina is known to produce high protein and phycocyanin of commercial importance with concomitant CO2
utilisation. The pH is one of the most important factors for cell growth, CO2 utilisation and controlling contamination.
In this study, an indigenously developed automated system for Spirulina cultivation was used at
pilot scale, where CO2 supply was aimed to provide carbon source and to control culture pH. Among all the
studied pH (7.5 ± 0.1,8.5 ± 0.1, 9.5 ± 0.1), pH 8.5 was found to be the best where biomass productivity, CO2
bio-fixation rate, protein and phycocyanin content were noted as 72 mg L−1 d-1, 0.13 g L-1 d-1, 64%, and 14%,
respectively. Though the culture at pH 9.5 experienced late CO2 feeding, it was healthy and showed almost
similar metabolite content compared to pH 8.5. The pilot scale automation system developed here can be employed
to enhance CO2 fed pH control based performance of Spirulina or any microalgae cultivation.
