Nutrient agar is the main growth media used for the isolation of a wide range of bacteria from various sources. It may also promote fungal growth, but the growth is limited due to the high pH of the nutrient aga
Nutrient broth is made up of water, beef extract, and peptone. Peptone is a nitrogen mixture of plant and animal sources. Agar is then added to make the mixture into a solid and is called nutrient agar. Agar Agar is a polysaccharide that comes from marine red algae. Polysaccharides are re...
Soft agar is generally around 0.7-0.8% agar in, say Luria-Bertani medium — although 0.35%, or even less, is not uncommon in certain protocols.Answer and Explanation: The main purpose of soft agar in any culture medium is to allow easy diffusion of the compound or entity of interest: for...
Agar slants can be used to culture bacterial cells for identification. Attempting to identify bacteria from a large sample is difficult because bacteria are small and can be difficult to find. However, when placed on a nutrient agar slant, bacterial cells will divide quickly and within several ho...
What are the bacteria using for nutrients in nutrient agar? What parts of a cell are visible under a light microscope? What organelles are found in epithelial cells? What are primordial germ cells? What is the substrate of the enzyme amylase?
Gelatin is a protein mainly derived from animal sources; however, there are a few plant-based sources of gelatin that can be used as substitutes for traditional animal-derived gelatin. These include Agar agar Agar agar is a vegan gelatin alternative made from red algae. It has a variety ...
Prosthecae is a semi-rigid extension of the cell wall and plasma membrane. It increases nutrient absorption and also helps in adhesion. 5. Cell Wall The cell wall is a rigid structure made up of peptidoglycan that surrounds the plasma membrane as an external coat. It is 10 -25 μm in ...
What are the bacteria using for nutrients in nutrient agar? What are bacterial cell walls made of? What are the main parts of a bacterial cell? What is one way that bacterial and archaeal cells differ from each other? What bacteria reduces sulfates under anaerobic conditions?
Why it is beneficial for cells to be small? What is the function of albumin in the human body? What is the purpose of reabsorption in the nephron? Why is cell culture important? What purpose does the nutrient agar plate serve? What is the primary function of erythrocytes?
Smoke water is sometimes used to promote germin- ation of garden and horticultural seeds, and can be purchased commercially or easily made. However, many commercial smoke germination products are made from combusting wood that, because of its high lignin content, produces germination inhibitors. ...
