Study Notes
Methane Producers
- Methanogens are a group of bacteria known for being methane producers.
Syphilis
- Treponema pallidum is the bacterium responsible for causing syphilis.
Diarrhea
- Bacteria associated with causing diarrhea in humans include Escherichia coli and Vibrio cholerae.
Nitrogen Fixation
- Certain bacteria, such as Rhizobia, are capable of fixing nitrogen in the soil independently.
Gliding Bacteria
- The group of bacteria known as Cytophaga-Flavobacterium are sheathed and gliding in nature.
Gonorrhea
- Neisseria gonorrhoeae is the bacterium responsible for causing gonorrhea.
Bergey's Manual
- Bergey's Manual of Systematic Bacteriology serves as a primary reference for bacterial classification and identification.
Enterobacteriaceae
- Enterobacteriaceae, or enterics, are a type of bacteria that includes Escherichia coli and Salmonella.
Cholera
- Vibrio cholerae is the bacterium responsible for causing cholera.
Eubacteria vs Archaeobacteria
- A key difference between Eubacteria and Archaeobacteria is the type of fatty acids found in their cell membranes.
Bacillary Dysentery
- Shigella is the bacterium responsible for causing bacillary dysentery.
Eubacteria Cell Membranes
- Eubacteria have ester-linked fatty acids in their cell membranes.
Hydrogen Sulfide
- Some bacteria, such as Desulfovibrio, release hydrogen sulfide in the atmosphere.
Lipid Bonding
- The domain Eukarya shares a similarity with Archaea in terms of lipid bonding.
Obligate Parasites
- Chlamydia is an example of obligate parasites.
Archaea Cell Membranes
- Archaea have ether-linked fatty acids in their cell membranes.
Phototrophic Bacteria
- Phototrophic bacteria, such as Cyanobacteria, utilize light as an energy source and do not evolve oxygen.
Protein Synthesis in Archaeobacteria
- Protein synthesis in Archaeobacteria begins with the formation of a 70S initiation complex.
Mycobacteria
- Mycobacteria have a characteristic feature of being resistant to staining due to their unique cell wall composition.
Diphtheria
- Corynebacterium diphtheriae is the bacterium responsible for causing diphtheria.
Nitrogen-Fixing Organisms
- Frankia is a nitrogen-fixing organism in non-leguminous plants.
Mycelium-Forming Bacteria
- Actinomycetes are a type of bacteria that forms mycelium, similar to fungi.
Mycoplasma Colonies
- Mycoplasma colonies have a characteristic "fried egg" appearance on agar.
Hypersaline Habitats
- The primary source of the green color in hypersaline habitats is due to the presence of halophilic green algae, such as Dunaliella salina.
Hypersaline Lake
- The green color in the hypersaline lake, Lake Magadi, is primarily due to the halophilic green alga, Dunaliella salina.
Pigmented Microorganisms
- Pigmented microorganisms, such as Halobacterium, are growing in the pH 10 soda lake.
Cell Disintegration
- Cells disintegrate at pH 7 due to the presence of water.
Thermoplasma Acidophilum
- Thermoplasma acidophilum is a type of archaeon that lacks a cell wall and grows at high temperatures and acidic conditions. Its habitat is in hot, acidic coal refuse.
