SOCORRO- Seeking Out Corrosion

The intertidal zone in marine environments is particularly susceptible to high rates of steel corrosion, causing a significant risk to marine and costal infrastructure. This is a result of the electrochemical environment, but also in many cases, microbial colonisation of the steel structure. The combined effect is referred to as Accelerated Low Water Corrosion (ALWC). In this study, we have carried out 16S rDNA sequencing of material recovered from corrosion samples, seawater and bed sediment to identify the populations responsible for ALWC and their potential sources in the environment. Samples are selected from three different UK sites- two sites with evidence of ALWC (Shoreham and Newhaven ports) and one without (Southend-on- Sea).

海洋环境中的潮间带（intertidal zone）极易发生高速率钢材腐蚀，对海洋及沿岸基础设施构成显著安全风险。该现象的成因既包括其特殊的电化学环境，在多数情况下还与钢结构表面的微生物定殖相关。二者的协同作用被称为低潮加速腐蚀（Accelerated Low Water Corrosion，ALWC）。本研究针对从腐蚀样品、海水及底泥中采集的物料开展16S rDNA测序分析，以明确与ALWC相关的微生物菌群及其在环境中的潜在来源。本次采样选取了英国的3处不同点位：其中2处存在ALWC现象（肖勒姆港与纽黑文港），剩余1处无该现象（滨海绍森德）。
