Next Stage of Japanese Competition Policymost produced extracellular surface-active polymers . Several of these microbially produced surface active polymers will be discussed here. All of these are complex, high molecular weight anionic heteropolysaccharides that may require additional components (lipids or proteins) for their maximum surface activity.

,Bacterial γ-Poly(glutamic Acid),glutamate repeat units. γ-PGA differs from proteins, however, in that the glutamate repeat units are polymerized by a ribosome-independent process. Furthermore, the glutamate repeat units are linked between the α-amino and γ-carboxylic acid functional groups (see below) .
