“…The extraction of metals such as Cu, Ni, Zn, Cr and precious metals from PCB scrap is technically feasible by the use of bacteria-assisted reaction (Brandl et al, 2001;Faramarzi et al, 2004;Karwowska et al, 2014). Brandl et al (2001) indicated that it is possible to mobilize metal from E-waste by the use of the microorganisms such as bacteria (Thiobacilli) and fungi (A. Niger, P. Simplicissimum).…”

“…Printed circuit board is an important and essential component of all electronic and electrical equipment, containing lots of valuable metals together with the number of hazardous metals or minerals which can harm the environment as well as human health (Karwowska et al 2014;Ilyas and Lee 2014;Willner et al 2015). Therefore, there is an urgent need for the recovery of valuable metals from PCBs.…”

Background: E-waste management is extremely difficult to exercise owing to its complexity and hazardous nature. Printed circuit boards (PCBs) are the core components of electrical and electronic equipment, which generally consist of polymers, ceramics, and heavy metals. Results:The present study has been attempted for removal of heavy metals from printed circuit board by metalresistant actinobacterium Streptomyces albidoflavus TN10 isolated from the termite nest. This bacterium was found to recover different heavy metals (Al 66%, Ca 74%, Cu 68%, Cd 65%, Fe 42%, Ni 81%, Zn 82%, Ag 56%, Pb 46%) within 72 h under laboratory conditions. The metal content of PCB after bioleaching was analyzed by ICP-MS. The crude PCB and bioleaching residue were characterized by FT-IR, XRD, SEM for the determination of structural and functional group changes for confirmation of bioleaching. Conclusion:The findings of the present study concluded that Streptomyces albidoflavus TN10 is a promising candidate for bioleaching of heavy metals from the printed circuit board as an eco-friendly and cost-effective process. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…Compared to chemical leaching, this technology has the advantages of being: (1) environmentally friendly, (2) low energy input and (3) low chemical cost. Due to these benefits, bioleaching has been used broadly in recovering metals, such as: Cu, Ni, Cr, Zn, Pb, Cd, Au from sulfidic low-grade ores (Watling et al 2014) (Sutar and Awasare 2015), printed circuit boards (Karwowska et al 2014), and various industrial solid wastes (Karwowska et al 2015;Mishra and Rhee 2014). It has been estimated that as much as 15% of copper and 5% of gold production worldwide utilize microbial-assisted extraction technology (Johnson 2014).…”

Coal fly ash originated from coal combustion has high concentrations of metals. If suitable leaching techniques are identified, then coal fly ash could serve as a useful source of valuable minerals including rare earth elements (REEs). In this study, three microbial strains, Candida bombicola, Phanerochaete chrysosporium and Cryptococcus curvatus were tested on their performance of leaching trace elements and REEs from fly ash. Through comparing mineral loss and leaching efficiencies resulting from indirect leaching or use of the culture supernatant, C. bombicola was identified to be the best leading to the highest mineral loss and extracting efficiencies of trace elements and REEs among the three strains. The highest mineral loss observed from using the supernatant of this yeast strain was 59.7%. Among all trace elements, As and Mo had the highest leaching efficiency of 80.9% and 79.5%, respectively. The same leaching test led to 67.7% of Yb and 64.6% of Er dissolved from the ash. This study, thus, demonstrated that bioleaching is feasible for leaching metals out of fly ash. The C. bombicola strain deserves further investigation due to its robust actions on metal leaching.
