Production of value-added chemicals from lignin-related materials using biotechnological process

Sulfur is an essential element for bacterial growth and is normally acquired through the assimilation of inorganic sulfate. However, in some environments, sulfate may not be freely available because inorganic sulfate constitutes less than 5% of the total sulfur in the environments. Thus, several bacterial species have evolved the ability to use a wide variety of organosulfur compounds such as dimethyl sulfide(DMS), and both the genes and enzymes involved in the use of such compounds have been studied in detail. We tried to develop a method for production of useful chemicals such as sulfur amino acids from biomass-derived DMS using such sulfur-starvation-induced enzymes.
