The nutrient broth is a basic media used for growing a broad variety of microorganisms in the laboratory. The nutrient broth consists mainly of 1.5g * L ^ - 1 extract, 3g * L ^ - 1 yeast extract and 5g * L ^ - 1 sodium chloride dissolved in distilled water. The nutrient agar is prepared by adding the agar at the desired amount into nutrient broth. Answer the following questions. marks) a) How would you prepare a 500 ml nutrient broth? b) How would you prepare 2% (w / v) nutrient agar for 1L? c) How would you prepare a 100 ml nutrient broth supplemented with 100mu * g / m * l ampicillin antibiotic? The stock concentration for ampicillin solution is 100mg / m * l .
