Application

Sulfolane is a polar aprotic solvent that may be used for the complete pyrolysis of cellulose without any polymerization or carbonization side reaction. Sulfolane, in combination with mesitylene, can be used as a solvent in the synthesis of poly(succinimide) (PSI) from L-aspartic acid. It can also be used as a solvent in the synthesis of chlorine-terminated polyethersulfone oligomer, a polymeric activator for nylon 6-polyethersulfone (PES)-nylon 6 block copolymer synthesis.

Sulfolane is an industrial solvent and emerging organic contaminant affecting groundwater around the world, but little is known about microbes capable of biodegrading sulfolane or the pathways involved. We combined DNA-based stable isotope probing (SIP) with genome-resolved metagenomics to identify...
