Abstract
Microalgae are ideal candidates for bioremediation and biotechnological applications However salinity and nutrient resource availability vary seasonally and between cultivation sites potentially impacting on biomass productivity The aim of this study was to screen pollutanttolerant freshwater microalgae Desmodesmus armatus Mesotaenium sp Scenedesmus quadricauda and Tetraedron sp isolated from Tarong power station ashdam water for their tolerance to cultivation at a range of salinities To determine if biochemical composition could be manipulated the effects of 4day nutrient limitation were also determined Microalgae were cultured at 2 8 11 and 18 ppt salinity and nutrient uptake was monitored daily Growth total lipid fatty acid FA and amino acid contents were quantified in biomass harvested while nutrientreplete and after 4 days nutrientdeplete D armatus showed the highest salinity tolerance actively growing in up to 18 ppt while Mesotaenium sp was the least halotolerant with decreasing growth rates from 11 ppt However Mesotaenium sp at 2 and 8 ppt had the highest biomass productivity and nutrient requirements of the four species making it ideal for nutrient remediation of eutrophic freshwater effluents Salinity and nutrient status had minimal influence on total lipid and FA contents in D armatus and Mesotaenium sp while nutrient depletion induced an increase of total lipid and FAs in S quadricauda and Tetraedron sp which was further increased with increasing salinity As none of the growth conditions affected amino acid profiles of the species these findings provide a basis for species selection based on sitespecific salinity conditions and nutrient resource availabilityThe project was supported by the Advanced Manufacturing Cooperative Research Centre AMCRC funded through the Australian Government’s Cooperative Research Centre Scheme grant number 222 The funders had no role in study design data collection and analysis or preparation of the manuscript and have provided permission to publish This research is part of the MBD Energy Research and Development program for Biological Carbon Capture and Storage Nicolas von Alvensleben was supported by an AMCRC PhD scholarship
