Answer:

1.Saccharomyces cerevisiae

Explanation:

2.As Swiss cheese is made up of warm temperature around 70 degrees the cheese is soft and malleable shermanii bacteria grows in that conditions and make larger holes

3.Language Assesment Battery or laboratory or Lactic acid bacteria

4. Toddy is an alcoholic beverage prepared by fermenting the sugar

5.Lactobacillus.It improves it's quality by increasing B-12 Vitamin

6.The BOD tests measures the rate of oxygen uptake by microorganisms in a sample of water. This test is performed during Biological treatment

(1) Saccharomyces cerevisiae (Brewer's yeast)

_____________________________

(2) Propionibacterium shermanii eats lactic acid, the waste product of the other two types of bacteria. It excretes, among other things, carbon dioxide. This carbon dioxide forms bubbles that eventually form the holes, or eyes, of Swiss cheese.

Propionibacterium shermanii.

(3) LAB = Lactic Acid Bacteria

(4) Toddy is an alcoholic beverage prepared by fermenting the sugar sap extracted from the palm plants. It contains 4 to 6 percent of alcohol and it is white in color. The terminology varies from one country to another. Toddy is also referred to the fermented flower sap of the the coconut palm tree.

(5) Lactobacillus is the bacteria which is used to convert milk into curd. Conversion of milk into curd is done by the process called fermentation.

When milk is converted to curd, the amount of lactic acid increases in the sample due to the action of the lactic acid bacteria. An increase in the amount of lactic acid is accompanied by the increase in Vitamin B12, thus improving the nutritional quality of the curd.

(6) BOD, is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period.

500 mg/L is most polluted.

(7) Bio-fertilizers are organisms that enrich the nutrient quality of soil.

The main source of bio-fertilizers are bacteria,fungi and  cyanobacteria (blue-green algae). Bio- fertilizers include nitrogen fixers which are able to fix nitrogen either by living freely in the soil or associated symbiotically with plants.

For getting nitrogen RHIZOBIUM can act as a bio-fertilizer for legume plant.

Rhizobium forms an endosymbiotic nitrogen fixing association with roots of legumes and parasponia.The bacteria colonize plant cells within root nodules;here the bacteria convert atmospheric nitrogen to ammonia and then provide organic nitrogenous compounds to the plant.The plant provides the bacteria with organic compounds made by photosynthesis.

Azobacter/Azospirillum also provide nitrogen for non-legume crops.

(8)  Statins are cholesterol reducing agents.

They are produced by Monascus purpureus (Yeast).

They act by Competitively inhibiting the enzymes responsible for synthesis of cholesterol and are used as blood cholesterol lowering agents.

_____________________________

(9)  (a) used to treat certain infections caused by bacteria such as pneumonia and other respiratory tract infections, scarlet fever, and ear, skin, gum, mouth, and throat infections.

(b) Lactobacillus

(c) Different groups of these bacteria are spread in different ways—for example, through coughing or sneezing, through contact with infected wounds or sores, or during vaginal delivery (from mother to child).

(d) Cyclosporin

(e) It is able to ferment sugar into carbon dioxide and alcohol and is commonly used in the baking and brewing industries.

(f) Propionibacterium shermanii
