Proteobacteria (18) Flashcards
(10 cards)
1
Q
Spirilla
A
- same spiral shape
- Flagellear bundles, motile
- all gram negative
2
Q
Magnetospirillum
A
Have magnetesome, find surface of sediment
3
Q
Magnetotactium
A
magnetotaxis
4
Q
Bdellovibrio bacteriovorus
A
- Vibroid
- Preys on other bacteria
- very fast
- Behave like viruses - burrow in periplasm and drain the prey of all nutrients to become an elongated bdellovibrio. Release progeny.
5
Q
Vibroid
A
curved shape, not full spiral
6
Q
Budding or Stalked bacteria
A
- stalks, hyphae and appendages (all have cytoplasm - part of the cell)
- this is not flagella, pillus
- unequal cell division
- most are alpha
7
Q
Caulobacter
A
- stalked
- purpose of attaching to surface
- stalks attach together
- does not bud from stalk.
8
Q
Stella
A
- star shaped appendages
- found in low nutrient environments
- good for floating and increase S/V ratio.
9
Q
hyphomicrobium
A
- Budding
- hypha extending is where daughter cells are produced
- bud on tip of hyphae, get rosettes.
- daughter, swarmer, go attach somewhere else.
10
Q
Myxobacteria
A
- gliding motility
- move as group outward
- very large genome (quorum sensing, enzymes to break down stuff)
- chemoorganoheterotrophs
- leave slime trail
- found on decaying things
- make fruiting body and mixospores (need starvation and quorum
- all delta, defined by how they look (morphology)
