摘要:

从锈层中分离出黄色细菌, 经分子生物学技术鉴定为海藻希瓦氏(Shewanella algae, SA)菌. 采用分光光度法研究了其生长曲线的变化, 发现该细菌的生长分为3个阶段: 指数生长阶段、稳定阶段和衰亡阶段. 采用电化学交流阻抗技术、扫描电镜和荧光显微技术等方法研究了SA菌对Zn--Al--Cd牺牲阳极材料腐蚀行为的影响.结果表明, 含SA菌培养基的试样的开路电位要高于无菌培养基中试样的电位,电荷传递电阻R_ct值大于无菌培养基的R_ct值,说明该SA菌能够抑制试样的腐蚀. 分析原因是细菌在试样表面形成生物膜,隔离了腐蚀介质与试样的接触, 同时, 细菌的生长消耗了氧气, 抑制了腐蚀的发生;试样在含SA体系中, 5 d时, 其表面覆盖比较致密的生物膜; 而在不含细菌的体系中,试样表面有明显的腐蚀坑; 试样在含SA体系中7 d时, 生成比较完整的生物膜, 随着体系中营养物质及氧气的减少, SA菌逐渐减少, 11 d后试样表面附着的SA菌所剩不多.

Abstract：

Shewanella is a typical iron–reducing bacteria which can reduce insoluble ferric iron to soluble ferrous iron and consume oxygen, being considered as the reasons of corrosion inhibition. The main study on Shewanella algae (SA) is the degradation of environmentally harmful organic compounds and heavy metals, and there are very few reports on the interaction of metal corrosion and SA. In this paper, the bacteria isolated from yellow rust layer were identified as SA by using molecular biology techniques. The growth curve of SA was determined with spectrophotography. The results showed that the growth curve was divided into three phases: exponential growth phase, steady phase and decay phase. The effects of SA on corrosion of Zn–Al–Cd anode were investigated by using electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and fluorescence microscopy (FM).The results showed that corrosion potential for samples exposed to the culture medium containing SA was higher than that for samples exposed to the sterile culture medium during the whole experiment. R_ct value in the culture medium containing SA was much greater than that of anode in the sterile culture medium. The bacteria could inhibit the corrosion of the specimen. The reason was that a biofilm layer was formed on the sample surface and the oxygen was consumed through the metabolic activities of bacteria in the culture medium containing bacteria. The biofilm layer was formed on the 5th day in the culture medium containing bacteria. While in bacteria–free system, obvious corrosion pits and white corrosion products were seen on the sample surface. The complete biofilm was formed on 7th day, and it detached from the sample on 11th day because of the exhaustion of nutrients and oxygen, showing that the biofilm formation had a great relationship with the presence of nutrients and oxygen.
