Bacterial culture from a trainer. Scanning electon micrograph (SEM) of Brevibacteria. Brevibacteria are considered a major cause of foot and shoe odour because they ingest dead skin on the feet and, in the process, convert the amino acid methionine into methanethiol, which is a colorless gas with a distinctive putrid smell that has a sulfuric aroma. The dead skin that fuels this process is especially common on the soles and between the toes. The brevibacteria are also what give cheeses their characteristic smell.
