In this study, the ability of Haloarcula sp. IRU1 isolated from Urmia lake, Iran, for production of cruxrhodopsin as a biomacromolecule with nanofunction from textile wastewater was evaluated and optimized by Taguchi experimental design. According to Taguchi method, the optimum conditions at which high cruxrhodopsin production could be achieved were observed to be in the presence of textile wastewater at 0.25% volume/volume), yeast extract at 0.025% (weight/volume) and KH2PO4 at 0.005%) weight/volume). In conclusion, Haloarcula sp. IRU1 is capable of cruxrhodopsin production from textile wastewater in different conditions.
