Agar the commonly used solidying agent for nutrient media is

Agar, the commonly used solidying agent for nutrient media, is effective because most microorganisms cannot degrade it. However, there are microbes that can use agar as a nutrient source. To accomplish the goal of isolating an organism that can use agar as a nutrient, which of the following media would be the best choice? (Remember that agar is a sulfated polymer composed mainly of D-galactose, 3, 6-anhydro-L-galactose, and D-glucuronic acid.) Agar, glucose, phosphate buffer, magnesium sulfate, calcium chloride, trace elements Agar, ammonium chloride, phosphate buffer, magnesium sulfate, calcium chloride, trace elements Agar, glucose, ammonium chloride, phosphate buffer, magnesium sulfate, calcium chloride, trace elements Agar, peptone, yeast extract.

Solution

The answer id \" D \"

because Nutrient Agar is a general purpose, nutrient medium used for the cultivation of microbes supporting growth of a wide range of non-fastidious organisms. Nutrient agar is popular because it can grow a variety of types of bacteria and fungi, and contains many nutrients needed for the bacterial growth. and the composition of nutrient agar is given in OPTION D .

The uses of nutrient agar are :-

1. It is frequently used for isolation and purification of cultures.

2. It can also be used as a means for producing the bacterial lawns needed for antibiotic sensitivity tests. In actuality, antibiotic sensitivity testing is typically performed on media specially formulated for that purpose.
