Sulfate-reducing bacteria (SRB) and iron-oxidizing bacteria (IOB) are one of the typical representatives of anaerobic and aerobic bacteria. which can form a synergistic community (mixed species biofilm) on the surface of material. In this work. the corrosion behavior of X65 steel in seawater containing SRB and IOB was investigated with electrochemical impedance spectroscopy. https://herbsdailyes.shop/product-category/biotin/
