describe binary fission in 5 basic steps
- dna replication
- cell elongation
- cross wall/septum form membrane invagination
- cross wall completes
- daughter cells produced
how is dna organised in bacteria
0.25-3mm length
8*10^6 BP
1000-9000
genes
describe the pili/pilus
1-12um length
2-25 nm
cell adhesion
conjugation
what is polyhyrdroxybutyrate
a polymer in bioplastics
which is a lipid storage produced in stress by microorganisms - biosynthesis
describe a plasmid
1*10^5 BP
conjugation
antibiotic resistence
what is the tol plasmid
plasmid from pdueomonas
can use benzene ring as a carbon source
what is twitch motility
translocation over moist surfaces
grapple hook
1. extend 2. tether 3. retract
large number of genes
what is a polar flagellum, where can it be found
one flagellum sticking out
vibrio cholera
what is a petritrichous
when flagellum uniformly covers body surface
where is flagellum anchored?
the inner cell membrane
describe the bacteria flagellum
moves by proton motive force rotary engine 3000rp, 12mm/min 20nm wide
