Video on Identification of Lactic Acid Bacteria – Morphology, culture, and biochemical Tests

This video presents the identification and characterization of lactic acid bacteria (LAB), an important group of microorganisms widely used in food fermentation and biotechnology.

Students will learn how to recognize the main features of LAB, including their Gram-positive nature, cell morphology, non-spore-forming characteristics, and their role in lactic acid production through carbohydrate fermentation.

The video also explains the use of selective media and biochemical tests used to isolate and identify lactic acid bacteria and differentiate them from other bacterial groups.
