Influence of abiotic factors on Cu bioleaching and survival of Herbaspirillum sp.GW103 in abandoned mine soil |
| 초록 |
The present study was aimed to evaluate the prospective of diazotrophic Herbaspirillum sp. GW103, for bioleaching of Cu in mine soil. The strain GW103 exhibited Cu resistance (350 mg L-1) and it was confirmed by locating copA and copB genes. Green fluorescent protein tagged GW103 strain was used to evaluate the survival of the isolate in abandoned mine soil. The abiotic variables such as, temperature, incubation time, CaCO3, coconut oil cake (COC), and agitation rate were selected for the study and optimized using Response surface methodology based Box-Behnken design. The optimal conditions for maximum Cu bioleaching (66%) were 30°C, 60 h of incubation with 1.75% of CaCO3 and 3% COC at 140 rpm. Obtained results point out that the abiotic factors greatly influenced bioleaching of Cu from mine soils. |
