Chlorella is important green algae that can be used for bioremediation of wastewaters. It can highly tolerate adverse environmental condition. Wastewaters contain high levels of nutrients which can be used as appropriate mediums for algal culture. In this study the effects of using vitamins on the growth of microalgae Chlorella sp. were investigated in marine water and wastewater using various mediums including Guillard, Conway, TMRL and B complex medium. Culture mediums with seawater and wastewater had 5 and 6 different treatments, respectively. Each treatment was replicated tree times. According to the investigations it was found that there are significant differences in Chlorella growth in sterilized seawater, between the medium with Gillard vitamins and Conway vitamins and medium without vitamin and also between Conway medium and other treatments, including culture mediums containing vitamin compounds and no vitamins, while are not significant between the treatments with vitamin compounds and as well as between B vitamins medium and medium without vitamin in seawater. Significant difference was not found between treatments in non-sterile wastewater (p>0/05). Therefore, adding vitamin compounds or using Conway medium did not lead to a significant increase in the growth of Chlorella sp. in non-sterile wastewater.
