Q

give an example of useful fungi (useful to people) and what is it used for?

A

penicillium, which is used to produce the antibiotic penicillin

25
what are antibiotics used for?
they are used to kill bacteria
26
What was the first antibiotic discovered?
penicillin
27
what unit of measurement is used to measure viruses?
micrometers which is equal to 1/1000 of millimeter.
28
what the three processes that useful microorganisms are involved in?
1. Recycling nutrients 2. Fermentation 3. the manufacturing of anitibiotics
29
if microorganisms recycle nutrients what can they be known as? and what do they do?
Decomposers, which break down waste and dead organic matter and thus recycle nutrients into the soil.
30
define fermentation
The process of changing carbohydrates into acids, alcohols and carbon dioxide.
31
Define antibiotics
these are medicines that are used to treat infection caused by bacteria.
32
who first discovered that the growth of mould could kill bacteria?
Alexander Fleming
33
What chemical is produced by mould and what does this chemical do?
The chemical is called penicillin and it can kill bacteria.
34
Give examples of diseases caused by harmful microorganisms
