PROBIOTIC FOODS: HEALTHY WAY TO HEALTHY LIFE Anmol Kaur 1 , Sanu Arora 2 and Ravinder Nagpal 1 Department of Biotechnology, Lovely Professional University, Phagwara (Punjab), India. 2 Department of Biotechnology, Punjabi University, Patiala (Punjab), India.

Slide 2

History of Health Claims Persian form of the Old Testament (Genesis 18:8) states " Abraham owed his life span to the utilization of harsh milk." In 76 BC the Roman antiquarian Plinius suggested the organization of matured milk items for treating gastroenteritis . Metchnikoff guaranteed that the admission of yogurt containing lactobacilli brings about a decrease of poison creating microscopic organisms in the gut and this expands the life span of the host.

Slide 3

Probiotic Concept Probiotic ( Greek Language) " forever" . It was initially utilized by Lilly and Stillwell as a part of 1965 to portray "substances discharged by one microorganism which fortifies the development of another ". Parker was the first to utilize the term probiotic as in it is utilized today "living beings and substances which add to intestinal microbial parity". In 1989, Fuller endeavored to enhance Parker\'s meaning of probiotic with the accompanying qualification: "A live microbial food supplement which advantageously influences the host creature by enhancing its intestinal microbial equalization."

Slide 4

The probiotic idea: impacts applied by suitable microorganisms material free of the site of activity and course of organization. incorporate locales, for example, the oral depression, the digestive system, the vagina, and the skin. On account of probiotic sustenances, the wellbeing impact is typically in view of adjustment of the gastrointestinal small scale vegetation and, in this manner, taking into account survival amid gastrointestinal travel.

Slide 5

Probiotics: An edge over Antibiotics: Emergence of anti-microbial resistance smaller scale life forms. Obnoxious symptoms Probiotics: Non-intrusive Preventive Free from undesirable reactions

Slide 6

Where do Probiotics originate from??? The miniaturized scale biota of an infant grows quickly after the birth . It is at first ward predominantly on : the mother\'s smaller scale biota, method of conveyance, birth environment and seldom hereditary variables . The maternal vaginal and intestinal verdure constitutes the wellspring of microorganisms, which colonizes the digestive tract of the infant. After early stages probiotics are supplied to us by crude sustenances; lactic corrosive aged nourishments, for example, yogurt and cheddar; and probiotic supplements.

Slide 7

Gut Microflora Microbiologically, the gut has three important districts: the stomach, small digestive tract, and colon. The stomach has low bacterial numbers Facultative anaerobes, for example, lactobacilli, streptococci, and yeast are available at ;100 settlement framing units (CFU) per milliliter because of the low natural pH . The small digestive system has a bigger bacterial burden that comprises of facultative anaerobes, for example, lactobacilli, streptococci, and enterobacteria and anaerobes, for example, Bifidobacterium spp., Bacteroides spp., and clostridia at levels of ;10 4 –10 8 CFU/ml. Be that as it may, the colon, has an aggregate populace of 10 11 –10 12 CFU/ml of substance

Slide 8

(Fuller, 1992)

Slide 9

Factors influencing the intestinal small scale biological community Any move made to execute "awful" microscopic organisms basically murders "great" microbes too. Anti-microbials and different medications consumption Microbial contaminations Diet (very prepared, low-fiber nourishments) Chronic the runs Stress

Slide 10

Imbalance of intestinal small scale vegetation brings about: Poor dietary reaction Reduced viability of meds Physiological brokenness Accelerated maturing Cancer Deficient safe reaction Susceptibility to disease Physical inconvenience

Slide 11

Therapeutic Modulation of Gut Microflora The gut microflora is an imperative constituent in the digestive tract\'s protection obstruction. Particular variations in the intestinal microbiota may incline the host to infection. The ordinary gut microbiota can keep the excess of potential pathogens in the GI tract . The defensive and invulnerable obstruction of the human gastrointestinal (GI) tract is differing. Contd… .

Slide 12

It incorporates : the epithelial layer the mucous layer the mechanics of peristalsis desquamation activities of secretory IgA All of which effect bacterial connection After connection, colonic microscopic organisms are kept from blending with the host\'s eukaryotic cells by the epithelial layer, which goes about as a fundamental boundary to intrusion.

Slide 13

Selection of probiotic life form Safety Origin Functional perspectives Survival Adherence, colonization Anti-microbial items Immune incitement Genetic stable Prevention of pathogens (Mullan, 2002)

Slide 14

Major pre-essential properties for a microorganism to be acknowledged as a probiotic may be: It ought to be non-pathogenic, non-lethal and non-unfavorably susceptible. It ought to be fit for surviving and metabolizing in upper G.I. tract discharge in the gut environment e.g. Impervious to low pH, natural acids, bile juice, salivation and gastric corrosive. It ought to be human in starting point, hereditarily steady and equipped for staying practical for long stretches in field condition. It ought to have the capacity to regulate insusceptible reaction and give imperviousness to ailment through enhanced invulnerability or by the generation of antimicrobial substance in the guts. Contd… .

Slide 15

It ought to have a decent bond/colonization to human intestinal tract and impact on gut mucosal penetrability. It ought to be opposing against cancer-causing/pathogenic living being. It ought to groups clinically demonstrated medical advantage, e.g. gastrointestinal disarranges, persistant looseness of the bowels, clostridium difficle colitis, anti-infection agents related the runs, intense juvenile gastroenteritis. It ought to have technologic properties for business reasonability, for example, security of wanted qualities amid handling, stockpiling and transportation .

Slide 16

Established impacts of probiotics Aid in lactose assimilation Resistance to enteric pathogens Anti-colon tumor impact Anti-hypertensive impact Small entrail bacterial abundance Immune framework adjustment Blood lipids, Heart sickness Urogenital diseases Hepatic encephalopathy (Roberfroid, 2000)

Slide 17

Mechanism for the advantage of Probiotics: Adherence and colonization of the gut Suppression of development or epithelial authoritative/attack by pathogenic microbes and creation of antimicrobial substances Improvement of intestinal boundary capacity Controlled exchange of dietary antigens Stimulation of mucosal and systemic host insusceptibility (Harish and Varghese, 2006)

Slide 18

Advantages of Probiotics Produce lactic corrosive brings down the pH of insides and repressing bacterial lowlifess, for example, Clostridium, Salmonella, Shigella , E. coli, and so forth. Diminishes the creation of an assortment of poisonous or cancer-causing metabolites. Help ingestion of minerals, particularly calcium, because of expanded intestinal sharpness. Creation of β - D-galactosidase compounds that separate lactose . Contd… .

Slide 19

Produce an extensive variety of antimicrobial substances - acidophilin and bacteriocin and so on assistance to control pathogenic microbes . Produce vitamins (particularly Vitamin B and vitamin K) Act as boundaries to keep hurtful microbes from colonizing the entrails (Roberfroid, 2000)

Slide 20

Effects of probiotics on pathogenic microscopic organisms Probiotics lessen plasma levels of bacterial endotoxin fixations, by restraining translocation of microorganisms over the GI lumen into the circulatory system. Diminishes in translocation of microscopic organisms may happen as an aftereffect of the capacity of probiotics to fix the mucosal obstruction. There are a few ways probiotic microflora can keep pathogenic microscopic organisms from following and colonizing gut mucosa . Probiotics deny colonization by illness inciting microscopic organisms through rivalry for supplements, safe framework up-direction, generation of immunizing agents, and up-control of intestinal mucin qualities. contd…

Slide 21

Probiotics lower colon luminal pH and foster development of non-pathogenic commensal microscopic organisms by SCFA (Short Chain Fatty Acid) creation. One SCFA, acidic corrosive, has antimicrobial action against molds, yeasts, and microscopic organisms. Probiotics apply defensive impacts through generation of hydrogen peroxide and benzoic corrosive, which hinder numerous pathogenic, corrosive touchy microbes . (Sanders, 2003)

Slide 22

Antibiotic related loose bowels Disease Antibiotic treatment Diarrhea Disturbance of intestinal microbiota Clostridium abundance produces poison

Slide 23

Antibiotic related looseness of the bowels Disease Antibiotic treatment Probiotics Disturbance of intestinal Microbiota Clostridium excess in parity produces poison

Slide 24

Probiotics and Cancer Enzymes (Glycosidase, B-glucuronidase , azoreductase , and nitroreductase ) of the intestinal greenery change over the precarcinogens to dynamic cancer-causing agents Probiotics lessen: Fecal convergences of catalysts Secondary bile salts Reduce retention of hurtful mutagens that may add to colon carcinogenesis. Movement of L . acidophilus and L . casei supplementation in people diminished levels of these chemicals

Slide 25

Several components have been proposed in the matter of how lactic corrosive microorganisms may restrain colon malignancy: Enhancing the host\'s safe reaction Altering the metabolic movement of the intestinal microflora Binding and corrupting cancer-causing agents Producing antimutagenic mixes Altering the physiochemical conditions in the colon (Harish and Varghese, 2006)
