Multi -omics reveal lifestyle of acidophile, mineral-oxidizing model species Leptospirillum ferriphilumT

Biomining is a biotechnological process carried out in many parts of the world that exploits acid loving microorganisms to extract metals from sulphide minerals. One industrial biomining method is called ‘heap bioleaching’ where typically copper containing minerals are piled into very large heaps, acid and microorganisms are added to the top and the soluble metal is collected at the heap base.

The role of the different types of microbes in the process is to speed up metal solubilisation by oxidising

steps conducted to pellet cells for RNA and protein extraction

Protocol for the extraction of biomolecules (DNA,RNA,protein,metabolties) from the same sample. Originally intended for lipid accumulating organisms (LAO) from wastewater treatment plant samples.
So far succesfully used for pelleted cells from planktonic cultures.
