Title: NIST Finds that Ethanol-Loving Bacteria Accelerate Cracking of Pipeline Steels
Description: Micrograph of crack in X52 steel after the sample was subjected to mechanical forces for several days in an ethanol solution containing acid-producing bacteria, "Acetobacter aceti>. Researchers at NIST's biofuels testing facility found that the bacteria increased fatigue crack growth rates at least 25-fold compared to what would occur in air.
