Abstract
In this work, the diversity of microbial consortium coming from a shale gas well was initially analyzed by 16 S full length sequencing, and the primary bacteria are Arciella (53.37 %), Shewanella (43.61%), and Desulfovibrio (1.95 %). These bacteria can produce large amounts of H2S using sulfate as electron acceptor. Subsequently, microbiologically influenced corrosion (MIC) behavior and MIC inhibition mechanism of norfloxacin and clindamycin hydrochloride are studied. The bacteria in anaerobic microbial consortium (AMC) significantly accelerate steel corrosion, but norfloxacin and clindamycin hydrochloride both can effectively inhibit MIC at a low concentration (40 mg/L) with inhibition efficiencies of 85.2 % and 82.7 %, respectively.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
