How Have Bioinformatic Approaches Been Helpful in Designing Growth Media

How have bioinformatic approaches been helpful in designing growth media for intestinal bacteria such as Faecalibacterium prausnitzii?

A) Genes encoding enzymes for fermentation and production of butyrate have been found.
B) The genome is similar to other bacteria and thus the media for those other bacteria can now be used.
C) Bioinformatics has indicated genes for metabolism of sugars that can now be added to the growth medium.
D) Bioinformatics has revealed that this bacterium can make its own amino acids and thus they are not needed in the growth medium.
E) Bioinformatics has revealed that biosynthetic genes for certain amino acids and vitamins are absent. Now these can be added to growth medium and the bacterium will grow.
