Abstract

Microalgae are very important photosynthetic organisms in aquatic ecosystems and their use in biotechnology is increasing. One of the main uses is the addition of probiotic strains of lactic acid bacteria to algal biomass. In this research Chlorella vulgaris was used as a mechanical carrier of Bacillus casei and it was found that there is a strong relationship and the adhesion of the lactobacillus bacteria on the surface of the chlorella vulgaris as captured by EM. This indicates the ability to use the complex of algae and probiotic bacteria together as feed supplement which will enhance the function of these bacteria in the intestinal tract of aquatic animals.

Key words: Lactobacillus, mechanical carrier, algal biomass
