Can Microbes break minerals?
Microbes play a crucial role in breaking down minerals in a process known as mineral weathering or biomineralization. These microbes secrete organic acids, enzymes, and other compounds that dissolve minerals, making nutrients like phosphorus, iron, and other trace elements available to plants and the ecosystem. The key types of microbes involved in mineral breakdown are: 1. Bacteria a. Acidophilic Bacteria (Acid-producing bacteria) - Example: Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans - Role: These bacteria produce sulfuric acid from sulfide minerals (e.g., pyrite), leading to the breakdown of iron and sulfur-containing minerals. They are involved in the oxidation of iron and sulfur, which accelerates mineral dissolution, especially in acidic environments. b. Pseudomonas and Bacillus species - Role: These bacteria release organic aci...
