Method & Evidence

AimTo investigate the efficiency of bacterial strains in producing poly-3-hydroxybutyrate (P3HB) using xylose and sugarcane bagasse hydrolysate, and to optimize production conditions.

MethodExperimental research involving microbial screening, bioreactor studies, and chemical treatment of biomass.

ProcedureBacterial strains were screened for P3HB production from xylose. Sugarcane bagasse hydrolysate was subjected to different detoxification treatments, with activated charcoal proving most effective. Selected strains (Burkholderia cepacia IPT 048 and B. sacchari IPT 101) were then cultured in bioreactors using both purified carbon sources and treated bagasse hydrolysate. Production was further optimized by manipulating nutrient limitations (phosphorus vs. nitrogen) and carbon source mixtures (xylose and glucose).

Sample55 bacterial strains initially screened; 2 strains used for bioreactor studies.

ContextIndustrial microbiology and biotechnology, focusing on biopolymer production from renewable resources.

Variables

IVType of carbon source (bagasse hydrolysate vs. analytical grade), nutrient limitation (P vs. N), detoxification method.

DVPolymer content (%), polymer yield (g g(-1)), biomass density (g l(-1)), polymer productivity (g l(-1) h(-1)).
