Metal ion-enhanced photosynthetic bacteria for bioplastic production from kitchen waste digestate: performance and mechanism
The concentration of 10 mg/L Fe<sup>3+</sup> and 2 mg/L Mn<sup>2+</sup> significantly enhanced PSB biomass and PHB accumulation (<i>p</i> < 0.05). Enhancement mechanism was to increase the relative abundance of key microorganisms, improve metabolic functions, and promote the expression of key functional genes. This study provides new ideas and insights for efficient production of PHB.
