Background and Objectives: By improving technology at recent years, some new environmental problems created. Electronic waste is one of the important problems. Recycling of e-wastes is limited. Just some countries by using traditional methods are recycling e-wastes. Pyrometallurgy and hydrometallurgy are two recycling methods for e-waste. These traditional methods are expensive and non-ecofriendly. Bioleaching is a new and efficient method for e-waste recovery which by interacting microorganisms helps to metal recovery. In this article biorecovery of Cu, Al, Ni, Zn, Mn, Mg, Ba, Cr, and Fe from printed circuit boards using one-step bioleaching was studied. To this purpose computer printed circuit boards were fined and the particle size was in the range of 75-149 micron. Penicillium simplicissimum was adapted to 1% (w/v) of computer printed circuit boards. After adaptation and bioleaching process Cu, Al, Ni, Zn, Mn, Mg, Ba, Cr, and Fe were bioleached about 94%, 99/8%, 100%, 100%, 61%, 81%, 46%, 26%, and 100% respectively. This paper proved the great potential of the bio-hydrometallurgical route to recover base metals from electronic wastes using fungi.
