Abstract

In this paper, replacing complete or partly of growth mediums with secondarily wastewater was studied. Lipid content of Neochloris oleoabundans grown in a 0.3 X SE medium and autoclaved secondarily treated wastewater mixture was 22.27 % (w/w). The maximum biomass concentration of N. oleoabundans grown in wastewater with no additional nutrients was 0.636 g/L with 33% (w/w) glucose. Two culture lines, MA, and NA were isolated within our laboratory and could grow in secondarily treated wastewater with no additional nutrients. The maximum biomass concentration of MA in batch culture was 0.860 g/L and the sum of glucose and xylose was 40% (w/w). The maximum biomass concentration of NA was 1.562 g/l and the sum of glucose and xylose was 33.8% (w/w). The maximum specific growth rates of NA and MA were determined to be 0.0566 and 0.0337 per hour.
