利用土壤中蜡样芽孢杆菌（Ｂａｃｉｌｕｓｃｅｒｅｕｓ）寻找隐伏金属矿床是近年来受国外许多学者重视的一种探矿法．运用此法对我国两个金三角地区进行了尝试研究，详细叙述了蜡样芽孢杆菌的分离、培养和鉴定．在已知的金矿区均检测到了很明显的蜡样芽孢杆菌孢子计数异常，异常区每克土壤中的蜡样芽孢杆菌孢子数最高可达１９０００个，异常区比背景区要高几百至几千倍，并发现该异常与土壤中的金异常有一空间上的分离．蜡样芽孢杆菌法很适合于成矿远景区内的找矿工作
In recent years, the use of Bacilus cereus in the soil for prospecting for concealed metal deposits has been paid much attention by many foreign scholars. This method has been used to study the two Golden Triangle areas in China, detailing the isolation, culture and identification of Bacillus cereus. Significant counts of spores of Bacillus cereus were detected in the known gold mines, with up to 19,000 spores of Bacillus cereus per gram of soil in the anomalous area, and anomalous areas of several hundred to more than in the background Thousands of times and found that the anomaly has a spatial separation from the anomaly in the soil. Bacillus cereus is very suitable for ore prospecting work in the prospect area
