After cultivation of 10 days, the growth response of algae and consortium were estimated on the basis of percentage increase or decrease in chlorophyll a content, over standard growth medium BG11. Among four commercial tested strains; C. saccharophila UTEX 2911 and Scenedesmus sp UTEX1589 were shown 58% and 27% increase in chlorophyll a content in treated wastewater, respectively, in comparison of standard BG11 medium. The strain C. pseudococcum UTEX 214 and N. oleoabundans UTEX 1185 shown highest chlorophyll a in BG11 than in treated or untreated wastewaters. The C. pseudococcum UTEX 214 responded 41.2% and 50% less chlorophyll a in treated as well as in untreated wastewater, respectively, while N. oleoabundans UTEX 1185 acquired 31.14% and 38% less chlorophyll in treated and untreated wastewater, respectively, over BG11. The native algae consortium recorded 78% increase chlorophyll a in treated wastewater comparing to BG11 while in untreated wastewater it was recorded as 36% less than BG11 ( Fig. 3). Comparing growth response of consortium with the growth response of solo native strains in different culture media, it was found that consortium has shown best growth response and better stability than any of the pure microalgae strain cultured in regardless of any wastewater, nevertheless, BG11 clearly favor single native strains culture, as shown in Fig. 4
