Grapefruit seed extract - a new antibiotic? [Digital]

We read an article on the internet about a farmer who threw his grapefruit scraps on the compost heap. Except for the grapefruit seeds, everything was decomposed. Therefore, we want to investigate whether grapefruit seed extract has an effect on the proliferation of different microorganisms.

Therefore, we want to investigate whether grapefruit seed extract can stop the multiplication of different bacteria or even cause bacteria to die off. Since we also have bacteria in our body, for example for digestion, we want to investigate whether the grapefruit seed extract will fight these bacteria or is resistant.
