Poly(hydroxyalkanoic acid) (PHA) bioplastics are microbial energy reserves. Researchers are developing cost-effective production methods using diverse bacteria and efficient culture techniques to make these biodegradable thermoplastics more accessible.

Area of Science:

  • Biotechnology and Microbial Engineering
  • Polymer Science and Engineering

Background:

  • Poly(hydroxyalkanoic acid) (PHA) is a microbial biopolymer used as an energy reserve.
  • PHA is a promising biodegradable thermoplastic but is currently too expensive for widespread use.
  • High production costs limit the market availability of PHA compared to conventional plastics.

Purpose of the Study:

  • To explore methods for reducing the high production cost of PHA.
  • To improve PHA productivity through the use of diverse microorganisms.
  • To develop efficient culture techniques for enhanced PHA yield.

Main Methods:

  • Review of recently developed processes for PHA production.
  • Investigation of various bacterial strains for PHA accumulation.
