Abstract

This research characterized bacteria isolates from surfaces of corroded zinc and copper coupons. Corroded zinc and copper materials were collected carefully, from two different locations in Ken Saro-Wiwa Polytechnic Campus and were put in sterile McCartney bottles. Bacteriological analysis such as Gram staining, motility test, catalase test, indole test, oxidase test, methyl red test, Voges-Proskauer test, and citrate utilization test were carried out to ascertain the bacteria responsible for the corrosion. Two bacteria were isolated; Enterococcus which was seen to be responsible for the corrosion of zinc and Escherichia coli; which was responsible for the corrosion of copper. It is recommended that materials that can inhibit biocorrosion should be used to control or treat metallic substances of corroded materials
