It is essentially a broth culture filtrate of the penicillium mould.
Explanation:
- Alexander Fleming invented penicillin an antibiotic in 1928. These have been rated as the most important scientific discovery, being among the first antibiotics to be effective against bacterial infection.
- Penicillin belongs to different families that are selective against a large variety of bacteria.
- In fact, this antibiotic was discovered by fleming and accident in which he left a platter containing staphylococci open and was contaminated by green mould. There was an area of inhibited bacterial growth around the mould from which he inferred that the mould produced a material that inhibited bacterial growth. This was found to be a penicillium mould through further study.
- I assume penicillin is the most significant discovery so far because it was the first antibiotic ever discovered against bacterial infection in the absence of any drug.
Answer:
The risks of various pollution and infections increase with urban sprawl.
Urban sprawl can be described as a condition in which the people from urban area migrate to low residential areas due to which the city starts to expand more in size.
During urban sprawl, more water contamination is likely to be caused as the water available cannot support such a large number of migration. There is not proper sewage system due to which contamination arise and cause sickness in the people. Also, these areas have more pollution due to traffic jam situations which causes sickness.
