Abstract

(5Z)-4-bromo-5-(bromomethylene)-3-butyl-2(5H)-furanone (furanone) from the red marine alga Delisea pulchra was found previously to inhibit the growth, swarming and biofilm formation of Gram-positive bacteria (Ren et al., 2002, Lett Appl Microbiol 34: 293-299). In the present study, the Gram-positive sulphate-reducing bacterium (SRB), Desulfotomaculum orientis, was used to study the inhibition of mild steel corrosion due to the addition of furanone. The weight loss from batch coupon experiments incubated with 40 μg ml -1 furanone was reduced fivefold compared with samples that lacked furanone. Analysis of the metal surface with environmental scanning electron microscopy further confirmed the protection afforded by the addition of furanone. In agreement with the corrosion inhibition, most probable number (MPN) analysis showed that 20 and 40 μg ml-1 furanone inhibited 58% and 96% of the D. orientis growth respectively. Hence, furanone has the potential to inhibit microbial-induced corrosion related to Gram-positive bacteria.
