Microbiologie Course 4Micro-organismen:
Microbiële cellen
-metabolisme
-groei
-evolutie
-differentiatie
-communicatie
-genetische uitwisseling
-beweeglijkheid
Oorsprong van cellulair leven
,Fylogenetische boom
-gebaseerd op DNA sequenties van het gen
-coderend voor ribosomaal RNA (rRNA)
*LUCA= last universal common ancestor
Prokaryote vs eukaryote cel
Prokaryoten
Bacteria en archea
Organellen zijn afwezig
Circulair DNA
1 chromosoom
-geen kernmembraan
-transcriptie en translatie in cytoplasma
-cytoplasmamembraan: energie
- 1 – 5 micrometer
Archea (prokaryoten)
Meer verwant aan eukarya
Extremofielen
-thermofielen
-halofielen
-acidofielen
Methanogenen: productie van methaan
,Eukaryote micro-organismen:
Protisten
Roden en groene algen
Schimmels en gisten (fungi)
Virussen:
Micro-organismen
0bligaat intracellulaire parasieten
Infecteren zowel prokaryoten als
eukaryoten
Afwezig in de fylogentische
boom (tree of life)
Morfologie van bacteriën:
Cell grootte:
E.coli 1x 2 micrometer
Eukaryote cellen: 8 tot > 600 micrometer
Voordeel van klein zijn:
-oppervlakte: volume ratio
-groeisnelheid
-mutaties/evolutie
, Uitzonderingen
Epulopiscium fishelsoni
-staafvormig, lengte 600 micrometer
Thiomargarita namibiensis
-tot 750 micrometer in diameter: zichtbaar met blote oog!
Mycoplasma pneumoniae
-diameter 0,2 micrometer
Nanobacteriën
-diameter 0,1 micrometer
-pathogeen
De bacterie cel
Cytoplasma
Ribosomen
DNA (nucleoid)
Cytoplasma membraan
Celwand
Kapsel
Pilli/ fimbriae
Luchtblaasjes en opslag (granules)
Endosporen
Flagella
Cytoplasma
Macromoleculen, kleine organische moleculen, anorganische ionen:
-zouten, suikers, aminozuren, nucleotiden, etc.
Ribosomen, nucleoid, granules/insluitsels, luchtblaasjes, endosporen
Geen organellen
Ribosomen
Eiwitten en ribosomaal RNA (rRNA)
Small ribosome subunit + large ribosome subunit
Translatie van mRNA eiwitten
DNA
