ClearCurrent developments on polyhydroxyalkanoates synthesis by using halophiles as a promising cell factory
Researchers reviewed how salt-loving microorganisms called halophiles can serve as efficient biological factories for producing polyhydroxyalkanoates (PHAs), a class of biodegradable plastics that could replace petroleum-based plastics. Their high salt requirements naturally prevent contamination during large-scale fermentation, and advances in metabolic engineering are making PHA production cheaper and more scalable.
