Penicillium simplicissimum, isolated from weathering basalt, produced citric acid when grown in a glucose-mineral salts medium with basalt, granite, granodiorite, rhyolite, andesite, peridotite, dunite, or quartzite. After 7 days' growth as much as 31 percent of the silicon, 11 percent of the aluminum, 64 percent of the iron, and 59 percent of the magnesium in some of the rocks were solubilized, and a number of rocks showed altered infrared absorption in the silicon-oxygen vibration region.
从风化玄武岩中分离出的简单青霉，在含有玄武岩、花岗岩、花岗闪长岩、流纹岩、安山岩、橄榄岩、纯橄榄岩或石英岩的葡萄糖 - 矿物盐培养基中生长时会产生柠檬酸。生长7天后，一些岩石中高达31%的硅、11%的铝、64%的铁和59%的镁被溶解，并且一些岩石在硅 - 氧振动区域显示出红外吸收的变化。
