The phrase “probiotic” originates from a Greek word meaning “for life”. It is basically the live microorganisms which when taken in appropriate amounts gives a beneficial health effect to the host (mostly human beings). The probiotics have been widely used in dairy products, however, their application in the non-dairy foods is yet to be recognized. As per the statements given by The Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO), there is enough scientific substantiation to signify that some specific microbial strains are safe for human use and the probiotics provide health benefits. Characteristics of probiotics
The specific strains are selected based on the different characteristics

Oral and vaginal administration of Lactobacilli (in the form of yoghurt) is done by women to treat yeast infection. There is not much confidence yet to recommend this method professionally.
Besides people with impaired immune function, probiotics are already present present in the digestive system. It is important to be aware of the ingredients and read the labels carefully.
Food applications of probiotics
The easy access to knowledge these days have led to the development of a diverse range of healthy food. The consumers have shown an increased amount of interest in functional foods including probiotics as seen in the last 20 years. The presence of probiotics in commercial food products have various health benefits. Because of the same reason, food industries are really focusing on creating a new generation of ‘probiotic health’ foods.
The food applications are :
Dairy-based probiotic foods
Most milk and milk products are stored at refrigerated temperatures which makes it a good vehicle of probiotic strains. Various examples of foods containing probiotics are fresh milk, yogurt, cheese, etc. the reason why dairy products are used is because they provide a suitable environment for growth and viability of healthy bacteria. Factors that need to be addressed
Last test, inoculation of phenylalanine agar is used to determine if phenylalanine deaminase oxidizes phenylalanine into phenylpyruvic acid and ammonia. Sixth test, is a Multiple Test Media used to determine the physiological characteristics of unknown #398. First test, Inoculation of Kligler 's Iron agar was used to determine the production of hydrogen sulfide from cysteine and fermentation of glucose and lactose. Last test, inoculation of litmus milk is used to determine the fermentation of lactose, casein, lactalbumin, and
Mannitol Salt Agar (MSA) plate, MacConkey agar (MC) plate, Eosin Methylene Blue agar (EMB), and Hektoen Enteric Agar (HEA) (3). The MacConkey agar plate and the Mannitol Salt agar plate are both used in the identification of the unknown. The MC plate is a selective and differential medium. It is considered a selective medium because the bile salts and crystal violet aspect of the medium prevent the growth of gram positive bacteria (3). This medium is differential because of the lactose and neutral red.
The author starts by explaining the human microbiome and the research on it. For many years, biologists thought that the human body was able to perform all of its important functions by itself. However, in the past decade, they have found that the human body contains trillions of microorganisms that help with these important processes. In fact, they outnumber human cell 10 to one. At first, microbe research was only focused on harmful pathogens, but recently, biologists have figured out what the most common bacteria in the human body are, and have been trying to figure out the specific functions of theses microorganisms.
I expect to learn the biochemical differences in bacteria from this lab. Also, how to identify different species of bacteria. Material & Methods For the first day of the practical, an unknown specimen was provided
This test was conducted utilizing aseptic technique. I first properly labeled the test tube and aseptically inoculated an MR-VP broth tube with unknown bacteria number 5 using a sterile inoculating loop. After 4 days of incubation, I added 4 drops of methyl red ph indicator to the tube. The contents of the test tube turned yellow in color. This indicates a negative test result because unknown bacteria 5 utilized the butanediol pathway instead of the mixed acid fermentation pathway.
There were many important key factors that
In the laboratory, identification of an unknown bacterium is often necessary. In the lab, a random sample consisting of three different bacteria was selected. The sample contained one gram-positive, one gram-negative paracolon, and one gram-negative coliform. The purpose of the experiment is to identify each of the three species that the mixture contained. After receiving an unknown mixture, the sample was streaked for isolation onto TSA, blood agar, and MacConkey plates.
Yeast infections most often occur in the moist areas of the body particularly on the mouth and genital area in both men and women. These are caused by many factors including poor diet, hygiene and stress management while the symptoms include red, painful and itchy sores, lesions and rashes. The good news is that natural remedies for yeast infection are often the only methods that anybody with a yeast infection will need to treat the condition. And even when over-the-counter medications are necessary, the following natural remedies are still a must because of their preventive value. Yeast infections are less likely to occur with healthy lifestyle changes since the causes are directly addressed instead of just providing temporary relief for the symptoms.
Introduction As we all know, bacteria is a very complex organism and the subject can be very broad. In this essay, the focus will be on bacteria and the bacterial cell structure. Different forms of bacteria, its pros and cons, the cell structure, diseases and resistance will be explained and listed. First bacteria and cell structure is explained, and then moving on to different bacterial forms and diseases, and how diseases can be prevented or even cured. Then finishing the essay will be the conclusion.
HOOK Weather chocolate milk should stay in schools is a debate in every school. To continue it shouldn’t be a debate though because, CL chocolate milk has high nutrients that students need. Chocolate milk should stay in schools because, R1 again they provide great and important nutrients. Some reasons as to why chocolate milk should be kept in schools are, R2It has extremely needed vitamins. R3Also, chocolate milk is better for you and better than most milks.
Using chitosan as a food preservative allows for reuse of this waste, making its use environmentally beneficial; while also reasonably cheap and cost-effective in production and usage. - Its biodegradability also allows chitosan biofilms to be beneficial to the environment. - The chitosan film has antibacterial and antifungal properties, meaning that it ultimately prolongs shelf-lives of the foods which it coats. - As chitosan film is a polysaccharide which physically coats the food product, it offers the advantage of being edible,
The media used in this experiment was Trypticase nitrate broth. The reagents used (A and B) were sulfanilic acid and alpha-naphthylamine (respectively). Using aseptic technique, the bacterium (16A and 16B) were inoculated into labeled broth test tubes. The tubes were incubated for 48 hours at 37 degrees Celsius. When the incubation was complete 5 drops of reagent A and 5 drops of reagent B were added to each of the broths.
These may be internal as well as external, the external ones particularly hard to gauge and hence their impact on the product or the organization comparatively uncertain to
