How do you test for Lactobacillus?

Methods: Probiotic Lactobacillus strain was isolated from a commercial yogurt and the characterization of the bacteria was performed using gram stain, motility, catalase, biochemical tests and morphological features were confirmed using scanning electron microscope (SEM).

What are Lactobacillus species?

Lactobacillus species are probiotics (“good” bacteria) normally found in human digestive and urinary tracts. They can be consumed for diarrhea and “gut health.” “Good” bacteria such as Lactobacillus can help the body break down food, absorb nutrients, and fight off “bad” organisms that might cause diseases.
