Poly(ethylene succinate) (PES) is an aliphatic synthetic polyester with a melting point from 103–106 °C. It is synthesized from dicarboxylic acids; either by ring-opening polymerization of
succinic anhydride Succinic anhydride, is an organic compound In chemistry, organic compounds are generally any chemical compounds that contain carbon- hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms) ...

Bacillus ''Bacillus'' (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum '' Bacillota'', with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural ''Bacil ...
'' sp. TT96 is found in soil and can degrade PES. Mesophilic PES degrading microorganisms were found in the ''Bacillus'' and '' Paenibacillus'' species; strain KT102; a relative of '' Bacillus pumilus'' was the most capable of degrading PES film. The fungal species NKCM1003 a type of '' Aspergillus clavatus'' also degrades PES film. The solubility of lithium salts (e.g. lithium perchlorate, LiClO4) in PES made it a good alternative to poly(ethylene oxide) (PEO) during early development of solid polymer electrolytes for lithium ion batteries.
