Implication

Randomized trial evaluates calcium alginate beads' effects on probiotic growth and release, indicating a scalable cultivation method.

Key Points

This research evaluates calcium alginate beads as a cultivation platform for probiotic bacteria, focusing on bacterial growth, release dynamics, and viability.
Calcium alginate beads were fabricated using sodium alginate at concentrations of 1.0–2.0% (w/v).
Structural stability, permeability, and pH resistance were assessed in the beads.
Lacticaseibacillus paracasei was the primary model organism used for evaluating encapsulation effects.
2.0% alginate showed 40% permeability compared to ~60% for 1.0% and 1.5% alginate variants.
Less than 1% of L. paracasei was released into the medium within the first 12 hours; approximately 8% was released after 24 hours.
Encapsulation improved bacterial viability, with better performance over 24–48 hours compared to liquid culture.
