A study has been undertaken to account for the presence of Thiobacillus acidophilus in iron-grown cultures of Thiobacillus ferrooxidans. Attempts to adapt T. acidophilus to ferrous iron were not successful but the facultative autotroph grew to a limited extent in the spent medium of T. ferrooxidans and was able to grow oligotrophically. Possible oligotrophic substrates were methanol, ethanol, and sulphide. Thiobacillus ferrooxidans may benefit from the presence of T. acidophilus because in mixed cultures some inhibiting organic compounds such as alcohols, organic acids, and amino acids were utilized by T. acidophilus. The number of T. acidophilus cells in heterogeneous cultures with T. ferrooxidans was of the same order of magnitude as the number of T. ferrooxidans cells as revealed by fluorescent-labelled antibodies.
已开展一项研究来解释嗜酸硫杆菌在氧化亚铁硫杆菌铁培养物中的存在情况。使嗜酸硫杆菌适应亚铁的尝试未成功，但这种兼性自养菌在氧化亚铁硫杆菌的废培养基中能有限生长，并且能够进行贫营养生长。可能的贫营养底物有甲醇、乙醇和硫化物。氧化亚铁硫杆菌可能因嗜酸硫杆菌的存在而受益，因为在混合培养物中，一些抑制性有机化合物，如醇类、有机酸和氨基酸被嗜酸硫杆菌利用。用荧光标记抗体显示，在与氧化亚铁硫杆菌的混合培养物中，嗜酸硫杆菌细胞的数量与氧化亚铁硫杆菌细胞的数量处于同一数量级。
