Corrosion behaviors of 0Cr18Ni9 stainless steel under the combination action of sulfate-reducing bacteria and V.natriegens Caixiang Gu1, a, Xiaoming Zhao1, b, Yansheng Yin2,c and Guijun Ji 1,d 1Merchant Marine College, Shanghai Maritime University, Shanghai 201306, China 2Institute of Marine Materials Science and Engineering, Shanghai Maritime University, Shanghai 201306, China acxgu@ shmtu.edu.cn, bzhaoxiaoming06@163.com, cyshyin@ shmtu.edu.cn Keywords: SRB; V.natriegens; 0Cr18Ni9 stainless steel; freely corroding potentials; polarization curves; EDS analysis.
Hence, further research and study on MIC is of great significance to material science.
Passive region decreases in single microbe and mixed microbe mediums, as a result of the presence of the microbiological secretion and corrosion products including acidic materials.
The reason may be after previous competition of mixed microbe in nutritive material, with the continuous supply of nutrients and their metabolic action made the growth environment improved and they promoted each other’s growth.

Firstly, liquid crystals that are nonchiral must be doped with chiral materials, which may potentially alter the flexoelectric behavior.
Also, the ULH texture is inherently unstable and is difficult to form, especially for materials with negative dielectric anisotropy.
