We here analyzed a sulfur index of Escherichia coli using LC-MSMS combined with thiol-specific derivatization by monobromobimane. The obtained sulfur index was then applied to evaluate the cysteine or ergothioneine producer. In addition, we introduce our recent research using a novel approach of multivariate analysis called "Sulfur Index Technology", which is based on sulfur compounds profile for foods.
