The valorization of bread waste into high-quality protein and biopolymers using the halophilic microorganism Haloferax mediterranei presents a sustainable approach to food management resource optimization. This study successfully coproduced poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) biopolymer with biomass content 8.0 ± 0.1 g L −1 productivity 11.1 mg h . fermentation process employed 3.0% w/v enzymatically hydrolyzed waste. amino acid profile cell revealed total 358 kg dry weight (DW), including 147 DW essential acids. quality, assessed through in-vitro enzyme digestion, indicated digestibility value 0.91 digestibility-corrected score (PDCAAS) 0.78. PHBV component (36.0 6.3% w/w) consisted copolymer 3-hydroxybutyrate 3-hydroxyvalerate in 91:9 mol% ratio. bioconversion not only mitigates but also generates valuable biomaterials.

Biopolymers are highly desirable alternatives to petrochemical-based plastics owing their biodegradable nature. The production of bioplastics, such as polyhydroxyalkanoates (PHAs), has been widely reported using various bacterial cultures with substrates ranging from pure biowaste-derived sugars. However, large-scale and economic feasibility major limiting factors. Now, algal biomass for PHA offers a potential solution these challenges significant environmental benefit. Algae, unique ability utilize carbon dioxide greenhouse gas (GHG) wastewater feed growth, can produce value-added products in the process and, thereby, play crucial role promoting sustainability. sugar recovery efficiency is variable depending on pretreatment procedures due inherent compositional variability among cell walls. Additionally, yields, composition, properties synthesized vary significantly microbial producers algal-derived Therefore, microalgal pretreatments synthesis copolymers still require considerable investigation develop an efficient commercial-scale process. This review provides overview discusses strategies enhance its properties, focusing managing GHGs sustainable future.

Abstract Biopolymer‐based fibrous aggregate materials (BFAMs) have gained increasing attention in biomedicine due to their excellent biocompatibility, processability, biodegradability, and multifunctionality. Especially, the medical applications of BFAMs demand advanced structure, performance, function, which conventional trial‐and‐error methods struggle provide. This necessitates rational selection manufacturing design with various intended functions structures. review summarizes current progress raw material selection, structural functional design, processing technology, application BFAMs. Additionally, challenges encountered during development are discussed, along perspectives for future research offered.
