1. Brief history of the company/factory ?

In 1930, Dr. Minoru Shirota, who was conducting research in a microbiology lab at the Medical Faculty of Kyoto University in Japan. He succeed in culturing a strain of lactic acid bacteria beneficial to human health. This bacterium was named "Lactobacillus casei Shirota strain. It took Dr. Shirota another 5 years of research to find the right food medium for the Lactobacillus casei Shirota bacteria. In 1935 the first bottle of Yakult, a fermented milk-based drink, was produced in glass bottles. The nurses that worked for Dr. Shirota, later referred to as Yakult Ladies, started distributing Yakult to customers. However, as word of the new product spread, demand surged – and in 1955, scientist Dr Shirota set up the Yakult Honsha Company in Japan. In that same year, he

It will discouraged the growth of harmful bacteria, stimulate our immune system protect our body from infections. The starter culture involved in Yakult manufacturing is Lactobacillus casei Shirota strain also known as the Shirota strain.

4. Describe the role of starter culture in the manufacturing of fermented dairy products.
The role of this starter culture is to convert sugars such as glucose or lactose to lactic acid during fermentation. Fermentation is a chemical reaction that bacteria perform to breakdown carbohydrates in order to release energy and multiply. They are able to live in our intestines, able to reach the intestine alive and proven scientifically to have a positive effect on our health. This starter culture do not stay permanently in our intestines as they move along our digestive tract and deliver their benefits before finally leaving the body when we have our bowel movement.

    Lactococcus lactis has two subspecies, lactis and cremoris, both of which are essential in manufacture of many varieties of cheese and other fermented milk products. Lactococcus lactis is related to other lactic acid bacteria such as Lactobacillus acidophilus in our intestinal tract and Streptococcus salivarius in the mouth. However, Lactococcus does not normally colonize human tissues and differs from many other lactic acid bacteria in its pH, salt, and temperature tolerances for growth, which are important characteristics relevant to its use as a starter culture in the cheesemaking industry. Lactococcus lactis is vital for manufacturing cheeses such as Cheddar, Colby, cottage cheese, cream cheese, Camembert, Roquefort and Brie, as well as other dairy products like cultured butter, buttermilk, sour cream and kefir. It may also…

    For this experiment, unknown sample #12 was used. The first step in identifying any unknown bacterium is to grow a culture on a nutrient agar plate. This bacterium was also plated on a MAC plate, which is both selective for gram-negative bacteria and differential as well. On the NA plate, bright red colonies were present; on the MAC plate there was bacterial growth as well, but no color change was observed. This lack of color change on the MAC plate indicated that the bacteria did not ferment lactose.…

    Gram Negative Unknown Lab Report #20 BIOL 3444-008 Giang Nguyen TA: Malini Kotak 11/05/2014 Abstract The experiment is conducted in order to identify a randomly given unknown gram-negative microorganism. By comparative analysis of biochemical tests that were performed throughout the semester to find out its characteristics and determine the identification of bacterium out of four potential unknown was given. To figure out the characteristics, T-streak was performed to isolate the sample from broth to a Tryptic Soy Agar plate, along with an additional slant in case something wrong with the original plate that can possibly affect the result.…

    If it is examined within 24 hours of plating it will demonstrate alpha-hemolysis, but if examined past 24 hours it will demonstrate gamma-hemolysis (2). Unknown 15 was examined after a one week incubation period, thus, it demonstrated gamma-hemolysis. Mannitol Salt Agar (MSA) was used to distinguish whether Unknown 15 belonged to the genus Enterococcus or Lactococcus. When streak plated onto the MSA medium, Unknown 15 grew on the plate and produced a yellow color change. The growth and color change (indicative of mannitol fermentation) resembled the the positive control Staphylococcus aureus.…

    According to research by Bode Science Center this bacteria is a rod shaped but comes in many different types of bacilli and may trigger local infections such as peritonitis, meningitis, appendicitis, and a bloodstream infection (Rauhut, n.d.). This bacteria is Catalase, oxidase, decarboxylase positive. It does not ferment any sugars nor sulfur. It is motile but also can be no motile. This bacteria is a strict aerobic bacteria that was isolated from fecal matter and then later discovered it is also found in stale beer.…

    The Mixed Broth culture contained two unknown bacterial cells and they either Gram-negative or Gram-positive. The procedures were followed as stated from the course laboratory manual by Meramec Community College (1). The first step was figuring out the unknowns was to separate the two bacteria. In order to do this, the Trypticase Soy agar was used. The streaking method was used to spread the bacteria across the Trypticase Soy agar to isolate the bacteria.…

    The purpose of performing physiological tests is to figure out certain characteristics of microorganisms or to reach a conclusion on what an unknown microorganism is. It can be also used to determine what is needed for bacteria to be cultured in or on certain media. Culture media can either be liquid or solid, and they can be used to identify certain characteristics of different bacterial species. This is indicated by the growth or lack of growth in or on certain media. Solid media can also be used to isolate organisms and provide a means to observe their morphology (Wiley 55).…

Description of non-pathogen: B. subtilis is a mesophilic, gram-positive bacillus that is commonly found in soil, although it can also survive in plants (1). B. subtilis are facultative aerobes, using butanediol fermentation or nitrated ammonification when oxygen is unavailable (1). The bacillus is motile by using a single flagellum and commonly forms biofilms which contain several B. subtilis all traveling in the same direction (1).…

    All three plates were studied, a gram stain was performed according to the referred laboratory manual noting their color and morphology, which was recorded in the journal. Gram-positive purple coccus bacteria and gram-negative rod/bacillus were identified using the microscope. The purpose of streaking on the MacConkey is to see if gram negative is lactose fermented or not and on the Mannitol salt agar if gram positive microorganism is able to ferment sugar. There were two types of bacteria that grew on the nutrient agar plates which were…

    The properties of selective and differential media suggest that differences between the bacterial species could be used in this lab to identify these six species but their effectiveness is unknown. The efficacy of identifying a completely unidentified bacterium in a cost-sensitive manner using these test also has yet to be determined. We hypothesized that applying a combination of selective and differential media with biochemical tests would provide a presumptive identification of the first group of six unknown bacteria. We also hypothesized the identification an unknown member of the Enterobacteriaceae family referred to as unknown #53 could be definitively identified using the API 20E and other tests. To test the first hypothesis, samples of four of the six unknown bacteria were streaked onto plates of Mannitol Salt agar, MacConkey agar, and Eosin Methylene Blue agar to examine their growth on the media.…
