Abstract

The escalating environmental concerns associated with conventional petroleum-based plastics have intensified research into sustainable alternatives. Microbial bioplastic production represents a promising solution, utilizing microorganisms to synthesize biodegradable polymers from renewable feedstocks. This review examines the current state of microbial bioplastic production, focusing on polyhydroxyalkanoates (PHAs), bacterial cellulose, and other microbially-derived polymers. We analyze production mechanisms, optimization strategies, economic considerations, and environmental impacts. Key challenges including cost-effectiveness, scalability, and material properties are discussed alongside emerging technologies and future prospects. The integration of synthetic biology, metabolic engineering, and circular economy principles offers pathways to enhance production efficiency and develop next-generation bioplastics with tailored properties.
