Inhibition of consortium sulfate reducing bacteria from crude oil for carbon steel protection

Inhibition of consortium sulfate reducing bacteria from crude oil for carbon steel protection

The efficiency of cetyltrimethylammonium bromide (CTAB) to reduce the activity of consortium bacteria consisting of sulphate-reducing bacteria (C-SRB) has been investigated on variable concentration by weight loss test, potentiodynamic polarization and diffusion disk methods. C-SRB was isolated from...
