question 59

Multiple Choice

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.
