Implication

Demonstrates the production of polyhydroxybutyrate in mixed microbial cultures using lignocellulosic hydrolysates, suggesting efficient waste conversion methods.

Key Points

This research aims to optimize the production of polyhydroxybutyrate (PHB) using mixed microbial cultures with lignocellulosic hydrolysates.
Single-factor experiments assessed the effects of substrate concentration, C/N ratio, and pH on PHB synthesis.
Microbial community composition was analyzed using 16S rDNA sequencing.
The highest PHB yield achieved was 612.35 mg/L at a substrate concentration of 1700 mg/L, C/N ratio of 31, and pH 7.0.
Nitrogen limitation and neutral pH significantly favored PHB production.
Chryseobacterium was identified as the dominant genus in all reactors.
