An anticorrosive study on potential bioactive compound produced by Pseudomonas aeruginosa TBH2 against the biocorrosive bacterial biofilm on copper metal
چکیده انگلیسی
In recent years, the control of MIC using green based chemical (bioactive) compounds were found to show promising results on this context, the present study evaluated the anti-corrosive role of pyocyanin bioactive compound produced by Pseudomonas aeruginosa TBH2 biofilm forms there Bacillus on the surface of copper metal CW024A (Cu). UV-Vis spectrophotometer and Gas chromatography-mass spectrometry (GC-MS) confirm that Pseudomonas aeruginosa TBH2 identified as potential production of bioactive compound (pyocyanin) was about 3.6 g/L. The activity of pyocyanin against the corrosive bacterial strain Bacillus sp. EN2, EN3 and EN9 on Cu and its control by pyocyanin were evaluated by weight loss (WL), surface analysis (X-ray diffraction spectroscopy (XRD)) and electrochemical studies (ES). The WL study showed a significant reduction about 0.002 ± 0.001 g of Cu when compared to biotic (0.007 ± 0.002 g) and abiotic system (0.003 ± 0.001 g). Biocorrosion system with pyocyanin was found to exhibit 72% corrosion inhibition efficiency. The results of XRD and ES evidenced the role of pyocyanin towards inhibition of the bacterial biofilm on Cu metal surface. Thus the present study has gained importance in reporting on a promising an alternative chemical and green biocide option to replace.
