Microbes are responsible for the production of substances that can stop the growth of other species. In this way, the microorganisms are able to avoid competition with other organisms for available nutrients. Bacteria can develop resistance to drugs by creating molecules that either change the structure of the drug, rendering it ineffective, or by altering their receptors, which prevents the medication from entering the cytoplasm. It is possible that a new medicine will be created that will circumvent the resistance mechanism developed by the bacteria. A different enzyme may be the target of the new medication than the one that was previously created. Petri dishes are filled with culture media containing the hydra component removed and combined with the culture media. Now, gram positive and gram negative bacteria are seeded onto the petri dish, and the dish is placed in an incubator for the night. If there is no growth, it is assumed that the hydra creates a substance that could be harmful to those germs.

Essentially microbes produce chemicals that inhibit other microbes to reduce competition and to protect themselves. Microbes, like all living organisms, have basic needs like food and want to stay alive. Microbes produce toxic chemicals to protect themselves from other microbes and to even eliminate competition for food.

Because bacteria are able to build resistance to antibiotics, there will always be a need for new antibiotic drugs. By creating and adding new chemicals together, scientists are able to create new drugs that are effective against resistant microbes. With the new chemical bonds, the drugs are able to inhibit different aspects of the microbe, thus killing it.

In 2008, scientists at the University of Keil in Germany were doing research on the defensive mechanisms on the sin of hydras. During their research, they discovered a protein, hydramacin, that is active against gram-negative and gram-positive bacteria.
