Abstract
Abstract An asparagine solution (0.1%) is required in the AOAC use-dilution method to cover stainless steel carriers during sterilization and storage. The rationale for using an asparagine soak is unclear. It has been proposed that asparagine enhances bacterial adherence to carriers or inhibits corrosion of the metal carriers or both. The former theory was assessed in this study by comparing bacterial adherence on seeded carriers stored in 0.1 and 1% asparagine solution to those stored dry or in water. The anticorrosive properties of asparagine on stainless steel carriers were microscopically evaluated after 9 months. The results demonstrate that asparagine neither enhances bacterial adherence to carriers nor is necessary to prevent corrosion.
