A
Lowest temperature at which a bacterium will grow
2
Q
Optimum
A
Temperature giving the most growth
3
Q
Maximum
A
Highest temperature that a bacterium will grow at
4
Q
Psychrophiles
A
- love the Cold
- range from 15-20 degrees C
5
Q
Mesophiles
A
- love middle temperature range
- range from 25-40 degrees C
- most human pathogens fall into this category
6
Q
Thermophiles
A
- love the heat
- range form 45-50 degrees C
7
Q
Capnophiles
A
-love CO2 and grow better in CO2 rich incubator
8
Q
Obligate Aerobes
A
Absolutely need O2 for growth
9
Q
Obligate Anaerobes
A
Require the absence of O2 for growth
10
Q
Facultative Anaerobes
A
Can grow without O2 but grow better in O2
11
Q
Microaerophilic
A
Require O2 for growth but at a lower concentration than in ambient (immediate surroundings) air.
