This editorial paper provides a synopsis of the contributions to the Bioengineering special issue "Advances in Polyhydroxyalkanoate (PHA) Production". It illustrates the embedding of the issue's individual research articles in the current global research and development landscape related to polyhydroxyalkanoates (PHA). The article shows how these articles are interrelated to each other, reflecting the entire PHA process chain including strain selection, metabolic and genetic considerations, feedstock evaluation, fermentation regimes, process engineering, and polymer processing towards high-value marketable products.
Keywords: bacteria; copolyester; feedstocks; fermentation; haloarchaea; metabolism; mixed microbial cultures; polyhydroxyalkanoate; process engineering; processing; pure culture; strain selection; sustainability; waste streams.
