Bacteriocins are peptides (or proteins) produced by bacteria (including LAB) that have antimicrobial activity against other bacteria. The use of bacteriocin-producing LAB strains in food processing may be of considerable benefit to consumer health due to the lack of toxic effect and their ability to act as natural preservatives and thus delay. contains acid that kills most harmful bacteria white cells surround and destroy microbes The body has many natural defences against harmful materials including microbes that cause disease ment of helpful bacteria in the gut lumen, while inhibiting Harper et al. (2) demonstrated that a small bowel effluent the harmful ones, may prevent initiation and/or progression (containing luminal bacteria) introduced into the defunctioned of the intestinal inflammatory cascade experienced in IBD colon of patients with CD treated by loop. We need bacteria. While previous generations used to think that all bugs and microbes were dangerous, nowadays we know that good bowel function - and indeed life itself - actually depends upon a healthy balance between the useful and the less useful types of bacteria. The healthy human body is home to some 100 trillion bacteria
Gut bacteria live in our intestine. The majority inhabit our large intestine, or colon (the longest part of the large intestine). Many intestinal bacteria are very helpful for us; some seem to have neutral effects on our lives; and a few are harmful This class has activity against gram-positive aerobes and anaerobes (bacteria that can live without oxygen), as well as some gram-negative anaerobes. The lincomycin derivatives may be used to treat serious infections like pelvic inflammatory disease, intra-abdominal infections, lower respiratory tract infections, and bone and joint infections Although people often think of bacteria and other microorganisms as harmful germs, many are actually helpful. Some bacteria help digest food, destroy disease-causing cells, or produce vitamins. Many of the microorganisms in probiotic products are the same as or similar to microorganisms that naturally live in our bodies Lactic acid bacteria (LAB) is found in curd. The useful applications of LAB are as follows: 1. These bacteria can convert milk into curd. 2. LAB are also found in our stomach to check the growth of harmful bacteria in our stomach. 3. LAB increases the amount of vitamin B12 in curd. Thus, it makes curd nutritious
