Abstract The production of bioplastics from marine microorganisms is significantly relevant in the field biotechnological applications for sustainable ecological management. Nevertheless, expense associated with PHB substantial and regarded as primary obstacle to its industrialization. In this study, orange peel waste served a carbon source enhance efficiency. Among 15 strains evaluated, MH 96 was selected due high salt tolerance efficient utilization substrate. highest producing strain MH96 genetically identified using 16S rRNA sequencing Halomonas meridiana submitted GenBank under accession numbers PP826284. optimal fermentation conditions were evaluated through single-factor optimization. Upon completion response surface optimization, Plackett–Burman Box-Behnken design experiments conducted utilizing outcomes final parameters inoculum size 1.74, (NH 4 ) 2 HPO concentration 1.0 pH 6.37, yield 5.94 g/L. characterization extracted biopolymer by NMR, FTIR, XRD, thermal properties used examine PHB, gas chromatography-mass spectrometry (GC–MS) proves presence 2-butenoic acid, 1-methyl ethyl ester, tetradecane, hexadecanoic methyl docosanoic 8,9,13-trihydroxy-. Methyl which confirmed structure polymer PHB.
