Coal seam gas water as a medium to grow Dunalliella Tertiolecta for lipid extraction

Aravinthan, Vasantha and Harrington, Daniel (2014) Coal seam gas water as a medium to grow Dunalliella Tertiolecta for lipid extraction. Desalination and Water Treatment, 52 (4-6). pp. 947-958. ISSN 1944-3994

Abstract

The Coal Seam Gas (CSG) industry in Queensland, Australia is expected to produce about 300 GL of CSG water annually as a by-product of its methane extraction processes. Surat basin aquifers typically produce sodium bicarbonate-chloride type water, having high concentration of salts making it unfit for direct beneficial use. The objective of this bench-scale investigation is to assess the potential of using bicarbonate-rich CSG water as a medium for growing Dunalliella tertiolecta for biofuel production. The rates of microalgal growth and carbon sequestration were found to be 49.7 mg SS/L/d and 29 mg C/L/d respectively, with an average total lipid content of 22% in CSG medium enriched with nutrients and amended for a salinity concentration of 10 gNaCl/ L and 200 mg carbon/L in non-aerated batch reactor. In summary, the brine resulting from reverse osmosis treated CSG water could be trialed as an ideal medium to grow the microalgae Dunalliella tertiolecta.
