Abstract

Seaweed qualifies as a valuable and abundant resource for producing polyhydroxyalkanoates (PHAs), which are microbial polyesters that serve as renew able and biodegradable alternatives to conventional plastics derived from fossil fuels. PHAs are biosynthesized and accumulated intracellularly by various microor ganisms, which act as carbon and energy storage compounds. However, the high production cost has hindered the widespread industrial production of PHAs. Extensive research has been dedicated to utilizing seaweeds and their by-products as affordable and sustainable substrates for producing PHAs in order to address this challenge. This chapter aims to provide a comprehensive overview from 2014 to 2023 of the recent advancements, challenges, and prospects associated with the microbial biosynthesis of PHAs using different seaweeds as carbon/nitrogen sources. Additionally, it examines in-depth seaweed-associated bacteria as novel bioreactors for PHA synthesis, shedding light on the symbiotic relationships between seaweed hosts and microorganisms that contribute to enhanced PHA yields with desirable properties.
