A point mutation in a <i>wspF-</i>like gene in <i>Pseudoalteromonas lipolytica</i> enhances the anticorrosion activity.

ABSTRACT: The protection of steel based on microbial biomineralization has emerged as a novel and eco-friendly strategy for corrosion control. However, the molecular basis of the biomineralization process in mineralization bacteria remains largely unexplored. We previously reported that Pseudoalteromonas lipolytica EPS+ strain provides protection against steel corrosion by forming a hybrid biomineralization film. In this study, we identified that a point mutation in the AT00_08765 (wspF-like) gene, responsible for encoding a chemotaxis protein that regulates swimming motility and polysaccharide production, is linked to the observed anticorrosion activity in EPS+ strain. The engineered point mutation mutant strain, designated Δ08765(707A), exhibited similar phenotypes to t
