Bioelectrochemical Characterization of Heavy Metals Resistant yeast: Hansenula fabianii Isolated from Tannery Wastewater
نویسندگان
چکیده
To date, heavy metals present a main drawback for bioelectrochemical systems (BESs) performances. Therefore, our results confirm, the first time, that Hansenulafabianii is an electrochemical active yeast has potential tolerance against various metals. The bioreactor inoculated by Hansenula fabianii in mediatoless conditions provided maximum current density of 32 mA/m²; up to 300 mA/m² in presence methylene blue. In mediatorless conditions, cyclic voltammetry (CV) on yeast pellet showed single oxidative peak at 450mV and pair peak, CV supernatant confirmed that Hansenula fabianii secretedits own mediator. obtained proved Hansenula based biofuel cell could be used simultaneous generation metal bioremediation.

متن کاملRemoval of Heavy Metals from Wastewater Using Cow Bone Charcoal
Bone charcoal, a mixed adsorbent containing around 10% carbon and 90% calcium phosphate, is mainly produced by thermal treatment of bones. Structurally, calcium phosphate in bone charcoal is in the hydroxyapatite form [1-2]. Traditionally, bone charcoal has been used to remove color in sugar solutions in the sugar refining industry. Recent studies use bone charcoal to adsorb radioisotopes of an...
متن کاملElectrokinetic enhancement removal of heavy metals from industrial wastewater sludge.
An enhanced electrokinetic process for removal of metals (Cr, Cu, Fe, Ni, Pb, Zn) from an industrial wastewater sludge was performed. The electrokinetic experiments were conducted under a constant potential gradient (1.25 V cm(-1)) with processing fluids of tap water (TW), sodium dodecylsulfate (SDS) and citric acid (CA) for 5 days. Results showed that metal removal efficiency of heavy metals f...
