| 内容記述 | Thirty species of microorganisms （8 bacteria, 9 actinomycetes, 8 fungi and 5 yeasts） were screened for maximal gold accumulation. Extremely high abilities to accumulate gold from the solution containing hydrogen tetrachloroaurate（III） were found in bacterial strains, such as Escherichia coli and Pseudomonas maltophilia. Most of actinomycetes, fungi and yeasts have less ability to accumulate gold in comparison with bacteria. Some of microorganisms can accumulate similar amounts of gold from the solution containing sodium gold（I） thiomalate as those from gold（III） solution. However, most of microorganisms tested accumulate far lesser amounts of gold from the solution containing sodium dicyanoaurate（I） than from the other two gold solutions. The accumulation of gold from the solution containing hydrogen tetrachloroaurate（III） by Pseudomonas maltophilia was very rapid, was affected by the pH of the solution, and obeyed the Langmuir adsorption isotherm. The Pseudomonas maltophilia cells immobilized with polyacrylamide gel adsorbed gold effectively from the solution containing hydrogen tetrachloroaurate（III）. The gold adsorbed on the cells was easily desorbed with 0.1 M thiourea solution. The immobilized Pseudomonas cells could be used repeatedly in the adsorption-desorption cycle using 0.1 M thiourea solution as desorbent. |
