Question

lactobacilli are harmful bacteria true or false explain me

Answer 1

Lactobacillus is a genus of Gram-positive, facultative anaerobic or microaerophilic, rod-shaped, non-spore-forming bacteria.[1] 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, and genital system. In women of European ancestry, Lactobacillus species are normally a major part of the vaginal microbiota.[2][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 mutualisticrelationship 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

Answer:

The gastrointestinal tracts of both humans and animals contain lactobacilli, which are not dangerous bacteria. They are a crucial component of dairy goods like milk, yogurt, etc.

Explanation:

• Due to their strong ability to produce significant metabolites and enhance the quality of the product, lactic acid bacteria, particularly those of the genus Lactobacillus, have been utilized in food microbiology, particularly in the fermentation of milk.
• The European Food Safety Authorities or the Food and Drug Administration's designations, such as "Generally Recognized as Safe" or "Qualified Presumption of Safety," provide further proof of lactobacilli's long history of safe usage.
• The basics of how bacterial cells function in the gut ecology can also be learned through the use of lactobacilli, which offer fascinating study opportunities.
• The enormous number of species and numerous groupings of species that have emerged from varied nutrient-rich environments have been acknowledged as making the taxonomy and phylogeny of the genus Lactobacillus highly difficult.
