Researchers from the South Australian Research and Development Institute (SARDI) are undertaking research programs on the culture of microalgae for biodiesel production. Microalgae are an attractive feedstock for biodiesel production because is its oil producing efficiency (up to 30 times higher per unit area of land relative to oil seed crops), and they can be cultured in poor quality saline water or effluents with high nutrient load. It is also said to contain a total oil content of 60% to 70% (dry weight basis). In addition to microalgae, SARDI is also looking into development of other feedstocks for biodiesel like canola and mustard..
