Method & Evidence

AimTo investigate the efficacy of enzymatic hydrolysate from asparagus waste as a low-cost substrate for producing polyhydroxyalkanoates (PHA) using Bacillus thuringiensis.
MethodExperimental design and optimization
ProcedureAsparagus husk waste was pretreated and enzymatically hydrolyzed. The resulting hydrolysate was then used as a supplement in a mineral-based medium for Bacillus thuringiensis fermentation to produce PHA. Optimization involved varying inoculum concentration and hydrolysate supplement percentage.
