### where doubling time is measured in lab

6

## binary fission

### cell dividing into two

7

##
period of no growth

synthesis of new enzymes

### lag phase

8

## where doubling time is measured in lab

### exponential log phase

9

## obligate means

### requried

10

## exact composition of media known

### defined

11

## facultative means

### have a choice

12

## binary fission steps

###
cell grows

copy DNA

form septum

seperate

13

## psychrophile

### -5 to 15C

14

## fastidious means

### it requires many growth factors

15

## 45 to 70C

### thermophile

16

## aerobe

### must use o2

17

## biofilm steps

###
adsoprtion (sense environment)

attach to surface

growth

exopolymer production (slippery coat)

attachment of other organisms

18

## defined media

### exact composition of media known

19

## stationary phase

###
population remains constant

cells die and others grow off dead cells

shrink in size to survive

20

## above 8 pH

### alkalophile

21

##
population remains constant

cells die and others grow off dead cells

shrink in size to survive

### stationary phase

22

## slime encased structure that holds bacteria onto a surface underwater

### biofilm

23

## must use o2

### aerobe

24

## biofilm

### slime encased structure that holds bacteria onto a surface underwater

25

## hyperthermophile

### above 70C

26

## types of media include

###
complex

defined

selective

differential

27

## exponential decline in population

### death phase

28

## media that prevents growth of some bacteria

### selective

29

## acidophiles

### less than 5.5 pH

30

## thermophile

### 45 to 70C

31

## selective media

### prevents growth of some bacteria

32

## cell dividing into two

33

## lag phase

###
period of no growth

synthesis of new enzymes

34

## less than 5.5 pH

### acidophiles

35

## salt loving

36

## Halophile

### salt loving

37

## anaerobe

### dies when o2 is present

38

## neutrophile

### 5.5 to 8 pH

39

## meaning it requires many growth factors

### fastidious

40

## dies when o2 is present

### anaerobe

41

## 25 to 45C

### mesophile

42

## distinguish types of bacteria biochemically

### differential

43

## doubling time formula

### (initial size)(time) = (initial size)(2^number of doublings)

44

## death phase

### exponential decline in population

45
