Question:
Does yogurt contain gram positive or gram negative bacteria or both?



Replies:
The typical strains are gram positive.

B. Zimmerman


Lactobacillus bulgaricus and Streptococcus thermophilus, which are commonly found in yogurt, are Gram-positive bacteria.

Judy Luke


To my knowledge, the main bacterial cultures used in yogurt include subspecies of Lactobacillus delbrueki and Streptococcus salivarius. Both are Gram positive bacteria.
