Typically known biopolymers [10,11,12].

Synthesized Polymers	Produced by Microbial Fermentation	Chemically Modified
Polycaprolactone (PCL)	Polylactic acid (PLA)	Lignocellulose (straw, wood)
Aliphatic co-polyesters (PBSA)	Polyhydroxyalkanoates (PHA)	Lipids and proteins (gelatin, soybean, gluten, collagen, whey)
Polyglycolic acid (PGA)	Poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV)	Starch (maize, wheat, potato, thermoplastics)
Aromatic co-polyesters (PBAT)	Polyhydroxy butyrate (PHB)	Others (chitosan, chitin, pectin, gum)
