Answer:

The most commercially important genus of lactic acid-fermenting bacteria is Lactobacillus, though other bacteria and even yeast are sometimes used. Two of the most common applications of lactic acid fermentation are in the production of yogurt and sauerkraut.

Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.

2. What structure caused rotifers to be called wheel animals or wheel bearers?

Tpy6a [65]

The structure that caused rotifers to be called wheel animals or wheel bearers is the corona.

Rotifers are also known as wheel animals or wheel bearers because of the corona structure around their mouth region.

Some rotifers are sessile and live inside tubes or gelatinous holdfasts that are attached to a substrate. Other rotifers migrate around a substrate through inch worming.

This is because when corona is seen in a sequential coordinated movement, it resembles the structure of a wheel, although it does not rotate in reality.

Therefore, we conclude that rotifers are called wheel animals or wheel bearers due to the presence of the corona structure.

Match the staining techniques with their purpose.

Dennis_Churaev [7]

A Negative stain such as India ink or Congo red-Look for the presence of a capsule.

This stain method is usually used to stain the area around the microorganism.

B The Gram stain-Divide bacteria into two groups based on cell wall structure (thick vs. thin).

This is type of differential staining used to distinguish organisms based on their staining properties. Gram + and Gram- bacteria stain different because of different cell wall structure.

C The Ziehl-Neelsen Acid-fast stain- Identify bacteria with waxy cell walls such as: Mycobacterium tuberculosis (the cause of TB).

This is also differential staining method which uses heat and phenol to derive dye into the cells with lipid-rich walls.

D Simple stain with a basic dye-Stain microbes a bright color to make it easier to see them in bright field microscopy.

One dye is used in simple staining in order to determinate the size, shape and arrangement of the cells.

E The Schaeffer-Fulton Endospore stain-Identify Bacillus or Clostridium species, such as the causative agents of anthrax, botulism, tetanus and gangrene.

This is a special type of staining only used for the bacteria that can form endospores. Bacteria are first treated with heat and then with malachite green, which is very strong stain that can penetrate endospores.
