Abstract

Background: Biosurfactants are derived from microbes, plants, and animals. Acinetobacter junii B6 is a lipopeptide biosurfactant producer previously investigated for its structure, physicochemical, and product aggregation properties.
Objectives: In this study, we investigated and optimized the bioencapsulation of A. junii B6 in calcium alginate hydrogel.
Methods: A. junii B6 was encapsulated using calcium alginate hydrogel. The formulation of the hydrogel was optimized using a full factorial approach. Sodium alginate concentration, calcium chloride concentration, and hardening time were selected as the main factors, and surface tension was the response measure. A scanning electron microscope (SEM) was used to study the bead’s
morphology.
Results: Scanning electron microscope image showed rounded and smooth beads. The most biosurfactant production and reduced surface tension (35.98 mN/m) were observed at concentrations of 1% calcium chloride, (1%) sodium alginate, and 15 minutes of hard-ening time. A. junii B6 can be encapsulated in alginate hydrogels producing biosurfactant at optimum experimental design.
Conclusions: This represents a practical method for optimizing the bioencapsulation of A. junii B6 to produce biosurfactants.
