You are going to grow E coli on MacConkeys Media Match the E

You are going to grow E. coli on MacConkey\'s Media. Match the E. coli colony phenotype when grown on MacConkey\'s Media to the appropriate interpretation:

1. Pink Colonies 2. White Colonies 3. No growth.

Options are.

a. They are gram positive mutants b. Ferments available lipids to base c. Uses something besides the available peptides for carbon and energy           

d. No carbon or energy source is available to the organisms. e. Ferments available carbohydrates to acid f. Ferments available carbohydrates to base g. g. Ferments available lipids to acid h. Uses something besides the available carbohydrates for carbon and energy i. Uses something besides the available lipids for carbon and energy j. Ferments available peptides to acid   

ONLY 3 options will match to Those 3 phenotypes. Choose the best answer.

Solution

1) pink colonies(gram -ive organism which is e.coli)- ferments available carbohydrates to acid (option-e)

2) white colonies(Lac- organisms such as salmonella, proteus) - ferments available lipids to base(option-b).

3) no growth - they are gram +ive mutants (option-a)
