Q

Food Processing/Bioprocessing/Biotechnology

A

The use of living organisms to make consumable products

17
Q

Bioreactor

A

A vessel/container in which biological reactions take place

18
Q

Aerobic Bacteria

A

Require oxygen for respiration

19
Q

Anaerobic bacteria

A

Do not require oxygen for respiration

20
Q

Obligate Anaerobic Bacteria

A

Can ONLY respire in the absence of oxygen (e.g between teeth)

21
Q

Facultative Anaerobic Bacteria

A

Can respire with or without oxygen

22
Q

Pathogen

A

A disease causing microorganism (bacteria, fungi, viruses)

23
Q

Antibiotics

A

Substances produced by microorganisms that stop the growth of/kill other microorganisms without damaging human tissue. Do not effect viruses.

24
Q

How do bacteria reproduce?

A

Binary Fission. Asexual - No gametes/no male-female parts involved

25
Q

Endospore

A

Bacteria can produce a tough wall when conditions are unfavourable. Cell breaks down, ES remains dormant until conditions are suitable
