Overview

Experimental study demonstrates efficient unsterile poly(3-hydroxybutyrate) synthesis from moldy corn using Halomonas sp. DYZ-4, indicating a cost-effective pathway for bioplastic production.

Key Points

To evaluate the feasibility and metabolic mechanisms of utilizing the halophile Halomonas sp. DYZ-4 for poly(3-hydroxybutyrate) synthesis from moldy corn in an unsterile fermentation system.
Characterized the fermentation performance and metabolic pathways of the halophile Halomonas sp. DYZ-4 under conventional and open (unsterile) culture conditions.
Pretreated moldy corn using α-amylase to generate reducing sugar feedstocks and optimized nutrient supply along with physicochemical parameters for biopolymer synthesis.
Enzymatic pretreatment of moldy corn with α-amylase yielded 10.72 g L–1 of reducing sugar.
PHB accumulation reached 6.81 g L–1 in the conventional system and 6.83 g L–1 in the unsterile open process, achieving an intracellular PHB proportion of 61%.
