- Archaea
- very different from bacteria, more similar to eukaryotes
- ARCHAEA- cell wall peptidoglycan, lipids are ether-linked/have branched carbon chains, rRNA sequences and RNA polymerase are similar to eukaryotes, sensitivity to antibiotics is not inhibited
- can live in extreme environments
- BACTERIA- cell wall has peptidoglygan, rRNA sequences are unique, RNA polymerase are small and simple, sensitive to antibiotics is inhibited, membrane lipids are ether linked or have unbranched carbon chains
- ARCHAEA- cell wall peptidoglycan, lipids are ether-linked/have branched carbon chains, rRNA sequences and RNA polymerase are similar to eukaryotes, sensitivity to antibiotics is not inhibited
- Phylum Crenarchaeota- Thermoacido-philes
- Metobolize sulfur, contain enzymes that function at high temperatu-re
- Phylum Euryachaeota-Methanogens and Halophiles
- Methanogens-> cannot use carbohydr-ates, lipids or proteins as energy sources, oxidize H2 with CO2 and produce methane, poisoned by O2, live in our guts
- Live in extreme environments-extremophile
- Untitled
- Live in saline environments (high concentration of salt)- halophiles
- live in very hot places (70'C-80'C)- hyperthermo-philes
- very different from bacteria, more similar to eukaryotes
- Metobolize sulfur, contain enzymes that function at high temperatu-re
