Dec 27, 2018· Nutrient Broth. 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.
Nutrient agar is used as a general purpose medium for the growth of a wide variety of non-fastidious microorganisms. It consists of peptone, beef extract and agar. This relatively simple formulation provides the nutrients necessary for the replication of a large number of non-fastidious microorganisms.
Jul 30, 2019· Nutrient Agar. One solution involves the mixing of agar with a nutrient broth, containing peptone and beef extract, to create nutrient agar. Carbohydrates, vitamins, salts, and trace amounts of organic nitrogen make up the beef extract. The principle source of organic nitrogen, amino acids, and long-chained peptides is the peptone.
A sample of liquid soap spread onto nutrient agar. A sample of liquid soap spread onto nutrient agar and a swab from a bar of solid soap also spread onto nutrient agar. Soaps are not designed to kill microbes. They help to wash them of your skin, better than water alone.
Jun 23, 2017· If agar is added to the nutrient medium, it is known as a nutrient agar medium. If agar is not added to the nutrient medium, then it is known as a nutrient liquid medium or a nutrient broth. Hence, the key difference between nutrient agar and nutrient broth is that nutrient agar contains agar while nutrient broth does not contain agar. CONTENTS. 1.
