Optical microscopic images (40x): microbeads made with 2% calcium alginate containing immobilized bacterial cells directly after formation using the electrostatic technique and during 4-week storage at a temperature of 4°C in fermented beverage. The irregular fragments visible in the images are the beverage ingredients.
