What inspired Fleming to search for a drug to treat bacterial infections?
Fleming found that some bacteria produce antibiotics but by mistake. He made a streak plate and it became contaminated by a fungi. He noticed around the bacteria that there was a clear space and deducted that the clear space contained antibiotics made by the fungi. This fungi was called penicillin notatum. Later Florey and Chain actually isolated the substance called an antibiotic. This term means against life. This antibiotic was mass-produced and eventually was used by the troops in World War II.
How is a clear zone in bacteria created?
A clear zone in bacteria, such as seen in a bacterial lawn on an agar plate, is usually formed when bacteria produce substances like antibiotics or enzymes that can inhibit the growth of other bacteria in the vicinity. This inhibitory effect leads to a clear or transparent zone around the bacteria that produced the inhibitory substance.
What is the container used for growing mold or bacteria called?
The container used for growing mold or bacteria is called a Petri dish. It is a shallow, flat dish made of clear glass or plastic with a lid to create a controlled environment for the growth of microorganisms.
Can bacteria kill other bacteria?
Yes. If you have ever been on Anti-biodics, then you should know. The medicine you take kills all bacteria (even the good ones). You take more medicine to replace the good bacteria. This medicine is called A-biotics.
What is a virus that attacks bacteria?
A bacteriophage is a virus that infects and replicates within bacteria. It injects its genetic material into the bacterial cell, hijacking its machinery to produce more phages. This ultimately destroys the bacteria and releases new phages to infect other bacterial cells.
