ABSTRACT Encapsulation of microalgae in hydrogel beads is a highly effective method for high‐yield cultivation. Emerging microfluidics‐based droplet generation techniques enable the miniaturization microalgae‐bead system. This provides enhanced control over encapsulation, precise size manipulation, and ability to study cell growth dynamics at microscale. paper explores behavior survivability encapsulated calcium alginate micro beads, along with structural stability various solutions. The solutions under investigation were pure BG‐11 medium, copper ion solutions, their mixtures. Encapsulated exhibited steady highest 1:50 dilution ratio. Exposure ions, particularly higher concentrations, adversely affected viability. No major degradation occurred across all conditions. Additionally, we conducted short‐term storage followed by regrowth experiments evaluate resilience recovery potential microalgae. results indicated that remained viable slowly proliferated during storage, although clustering end impacted efficiency. During observed noticeable increases bead shape changes. However, minimal geometric alterations subsequent phase.

Establishing a platform for the bioconversion of waste resources into value-added compounds is critical achieving sustainable and eco-friendly economy. Herein, we produced polyhydroxyalkanoate via microbial fermentation using cabbage as feedstock metabolically engineered Escherichia coli. For this, hydrolysis conditions were optimized by focusing on parameters such substrate enzyme concentrations to enhance saccharification efficiency. The phaABC operon, which encodes key enzymes responsible biosynthesis in Ralstonia eutropha H16, was overexpressed E. Using hydrolysate feedstock, this coli strain could produce poly(3-hydroxybutyrate) with polymer content 26.0 wt % dry cell weight. Moreover, malic acid significantly enhanced production; addition 0.5 g/L markedly increased 59.9%. This study demonstrates potential promising raw material production polyhydroxyalkanoate.
