ABSTRACT
Dramatically increasing costs of hydrocarbon raw materials stimulate the development of new polymers, which do not depend on production of oil and gas. Fermentative biosynthesis of poly(3-hydroxybutyrate) (PHB) and its homologues poly(3-hydroxyalkonoates) (PHAs) is based on using renewable substrates. Hydrocarbon wastes of food and wine/juice industries (sugars, molasses, starch etc.) are the basic “structural material” for bacterial PHB (and PHA). Utilization of hydrocarbons in biosynthesis of PHA is ecologically efficient.
