“…As the biosorbent surface became more negatively charged as the pH solution increased from 2 to 5, the functional groups of Y. lipolytica cells were more deprotonated and thus available for the metal ions. Li et al 23 and Özer and Özer 22 reported that as the pH increased to 5, more functional groups with negative charge such as carboxyl, amine or hydroxyl became exposed with a subsequent increase in attraction sites to positively charged ions, and thus enhanced the biosorption capacity. At a low pH, cell wall ligands were closely associated with hydronium ions H 3 O + and restricted the approach of metal cations as a result of the repulsive force 3 .…”

“…At a low pH, cell wall ligands were closely associated with hydronium ions H 3 O + and restricted the approach of metal cations as a result of the repulsive force 3 . A decrease in biosorption yield at a higher pH (pH>6) is related to the formation of soluble hydroxylated complexes of metal ions (nickel ions in the form of Ni(OH) 2 , zinc ions in the form of Zn(OH) 2 ) 23 . Similar conclusions were presented by many authors conducting research on the biosorption of nickel and zinc ions using different biosorbents 20, 22, 25 .…”

This study examined the biosorption process of Ni(II) and Zn(II) from an aqueous solution by dead biomass of Yarrowia lipolytica. Optimum biosorption conditions were determined as a function of pH, biomass dosage, contact time, and temperature. The biosorbent was characterized by FTIR, which indicated the participation of hydroxyl, carboxyl, amide and amine groups in the process of binding the metal ions. The results showed that the biosorption processes of both metal ions closely followed pseudo-second order kinetics. The equilibrium data of Ni(II) and Zn(II) ions at 20, 30 and 40 o C fi tted the Langmuir and Freundlich isotherm models. Langmuir isotherm provided a better fi t to the equilibrium data, with a maximum biosorption capacity of the Y. lipolytica biomass for Ni(II) and Zn(II) of 30.12 and 44.44 mg/g respectively. The calculated thermodynamic parameters demonstrated that the biosorption of Ni(II) and Zn(II) ions onto the Y. lipolytica was feasible, spontaneous and endothermic.

Biorecovery is emerging as a promising process to retrieve gold from secondary resources. The present study aimed to explore the uptake pattern of Pycnoporus sanguineus biomass for gold, identify the effective functional groups in gold recovery process, and thus further intensify the process via microbial surface modification. Results showed that P. sanguineus biomass could effectively recover gold with the formation of highly crystal AuNPs without any exogeneous electron donor. Under the conditions of various initial gold concentrations (1.0, 2.0, and 3.0 mM), biomass dosage of 2.0 g/L, solution pH value of 4.0, and incubation temperature of 30°C, the uptake equilibrium established after 4, 8, and 12 h, respectively. The uptake process could be well described by pseudo-second order kinetics model (R = 0.9988) and Langmuir isotherm model (R = 0.9958). The maximum uptake capacity of P. sanguineus reached as high as 358.69 mg/g. Further analysis indicated that amino, carboxyl and hydroxyl groups positively contributed to the uptake process. Among them, amino group significantly favored the uptake of gold during recovery process. When P. sanguineus biomass was modified by introduction of amino group, the gold uptake process was successfully intensified by shortening the uptake period and enhancing the uptake capacity. © 2017 American Institute of Chemical Engineers Biotechnol.
