Heterotrophic cultivation of microalgae can achieve much higher cell density and faster growth rate compared to photoautotrophic mode of cultivation, however the high costs of organic carbon prohibits heterotrophic cultivation from being economically feasible in industrial scales. In the present study, we considered the usage of sugar factory wastewater (SFW) as an inexpensive carbon source for cultivation of acido-thermophillic microalga Galdieria sulphuraria for the production of phycocyanin. The characteristic of SFW was studied in order to determine its suitability for use as an alternative carbon source for G. sulphuraria. In addition, we investigated the effect of various concentrations of SFW on algal growth and phycocyanin production. Phycocyanin content in G. sulphuraria (UTEX #2919) was analyzed via UV/Vis spectrometer and fluorescence microscopy. Our result indicated that the SFW can be used as an alternative carbon source for the cultivation of G. sulphuraria for the production of phycocyanin.
