Actinobacteria (+) - ANS--extremely diverse
-thin, filamentous to caccobacilli shape
-important to soil
-diff. peptidoglycans in cell wall
-Mycobacterium, Corynebacterium, Bifidobacterium, Gardnerella
Amensalism - ANS-organism A: harmed
organism B: unaffected
anoxygenic - ANS-does not produce O2
anoxygenic photosynthesizers - ANS-1. purple sulfur bacteria
(oxidize hydrogen sulfide to elemental sulfur & sulfuric acid)
2. purple non sulfur bacteria
(use only hydrogen)
3. green sulfur bacteria
(oxidize sulfide)
4. green non sulfure bacteria
(oxidize non-sulfide substrates)
Aquificae - ANS--gram (-)
-hyperthermophiles living in hot springs and oven vents
Archaea - ANS-distinguished by:
-Membranes with branched isoprene chains & ether linkages to phosphate head
-Walls of surface layer proteins(some pseudopeptidoglycan)
-Genomes are much larger -Capable of methanogenesis
-Usually not in human microbiota
-Not directly associated with infectious diseases
Archaea membranes - ANS-branched isoprene chains & ether linkages to phosphate
head

organism B: unaffected
competing communities result in - ANS-scarce resources
cooperative communities result in - ANS-biofilm formation
Corynebacterium spp. - ANS--Diaminopimelic acids in cell wall
-Most are non-pathogenic
- C. diphtheria is causative agent for diphtheria
Cyanobacteria - ANS--oxygenic
-highly adaptable and diverse
