The presence of intracellular debris and pigments post-lysis compromises polymer purity and color quality. Eliminating these contaminants ensures high-grade resin suitable for sensitive applications.

The keywords focus on specific high-value chemical outputs like gamma-butyrolactone and 1,4-butanediol from complex biomass. The primary technical challenge is the non-selective degradation of polymers into a mixture of low-value byproducts rather than targeted monomers.

The keywords focus on the synthesis of high-value chemicals like NMP and alkyl lactate from PHA biomass. The underlying problem is the inefficient or non-selective conversion of biopolymers into drop-in industrial solvents.
