Anticorrosion potential of two bioproducts in injection water header samples
In this study, we evaluated the anticorrosive, antibiofilm, and biocidal properties of twobioproducts, a bioemulsifier from Psychrobacillus antarcticus Val9 and a surfactin from Bacillusvelezensis H2O-1, using microcosms that simulate water injection header conditions. Thebioproducts were produced and characterized through emulsification indices under variousconditions, surface tension, and oil displacement assays. Their effects were assessed via carbon steelmass loss, scanning electron microscopy, epifluorescence microscopy, surface roughness analysis,ATP quantification, and molecular profiling of microbial communities.
