Employing the dialysis method, the authors designed experiments to probe into the effect of adhered Paenibacillus polymyxa on the dissolution of minerals within basalt as well as the effect of temperature on such adhesion_mediated dissolution. The results of ten days' experiment show that the dissolution of basalt is highly promoted by P. polymyxa and its metabolites at 30 ℃, with Fe, Mg and Mn being released mainly from olivine and Ca and Al from augite and feldspar. At 5 ℃, however, the promotion is very insignificant. Adhered bacteria and metabolites are advantageous to the release of Mg, Fe and Mn but disadvantageous to that of Ca. The reason is that these two groups of elements are released through different mechanisms which are diversely affected by adhered bacteria. The release of Al is insignificantly affected by the adhesion of bacteria. At 5 ℃, the adhered bacteria have no effect on element release.
