Question

lactobacilli are aerobic bacteria true or false if false correct the sentence
​

Answer 1

Answer:

Lactobacillus is a genus of Gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria.[2] They are a major part of the lactic acid bacteria group (i.e., they convert sugars to lactic acid). In humans, they constitute a significant component of the microbiota at a number of body sites, such as the digestive system, urinary system[citation needed], and genital system. In women of European ancestry, Lactobacillus species are normally a major part of the vaginal microbiota.[3][4] Lactobacillus forms biofilms in the vaginal and gut microbiota, allowing them to persist during harsh environmental conditions and maintain ample populations.[5] Lactobacillus exhibits a mutualistic relationship with the human body, as it protects the host against potential invasions by pathogens, and in turn, the host provides a source of nutrients.[6] Lactobacillus is the most common probiotic found in food such as yogurt, and it is diverse in its application to maintain human well-being, as it can help treat diarrhea, vaginal infections, and skin disorders such as eczema.

Answer 2

This is a false statement. Correct statement is- Lactobacillus is an anaerobic bacteria.

• Lactobacillus is a gram positive bacterium that grows in the absence of oxygen i.e. under anaerobic conditions.
• It has several benefits. It is involved in souring milk. The bacteria are found in the digestive tract of humans where it helps in the absorption of nutrients. It is also used for the treatment of diarrhoea or other digestive problems.
