Fungi are a good worker in many environmental duties, where the use of an organism to produce more than one product in the same medium is profitable. Exopolymer, total lipids and mycelium mass, etc... are the scope of different separate studies. In the present work a fungal Curvularia sp. strain DFH1 can act as oleaginous where it contain about 26% of its dry weight as lipids with a Fatty acid profile of hexadecanoic, octadecenoic, octadecanoic and erucic. Which have a valuable economic impact or it can act as a feed stock for biodiesel production, also and at the same time produce an exopolymer which act as a good powerful bioflocculants giving flocculation activity reached to 95%, The FTIR spectra of bioflocculant showed the presence of carboxyl, hydroxyl, amide and amino groups. And the cell debris functions as heavy metal absorbent biomaterial, where about 85% Cd(II) and 15% Zn(II) were removed by cell debris as biosorbent. So the purpose of this paper is to view the various attributes of the fungal isolate and explores the possibility of utilizing them in different ways in a manner of zero waste process.
