How are bacteria classified based on flagella?
Atrichous: No flagella (Example: Corynebacterium diptherae)
Monotrichous: One
flagellum
(Example: Vibro cholerae)
Lophotrichous: Bunch of flagella at one end (Example: Pseudomonas)
Amphitrichous: Flagella at both ends (Example:
Rhodospirillum rubrum
)
Peritrichous
: Flagella surrounding the cell (Example:
Bacillus
)
View source
What are the modes of nutrition for bacteria?
Phototrophs
: Gain energy from light
Photolithotrophs
: Use inorganic compounds
Photoorganotrophs: Use organic compounds
Chemotrophs
: Gain energy from chemical compounds
Chemolithotrophs
: Use inorganic compounds
Chemoorganotrophs: Use organic compounds
Autotrophs
: Use CO2 as carbon source
Photoautotrophs
: Use light
Chemoautotrophs
: Use chemical energy
Heterotrophs
: Use organic compounds as carbon source
View source
What are the classifications of bacteria based on temperature requirements?
Psychrophiles
: Grow at
0°C
or below
Psychrotrophs
: Grow at 0°C, optimum 20-30°C
Mesophiles
: Grow best at
25-40°C
, optimum
37°C
Thermophiles
: Grow above
45°C
Hyperthermophiles
: Optimum above
80°C
View source
What are the classifications of bacteria based on oxygen requirements?
Obligate Aerobes
: Require oxygen (Example:
Pseudomonas
)
Facultative Anaerobes
: Can grow with or without oxygen (Example:
E. coli
)
Obligate Anaerobes
: Cannot use oxygen (Example:
Clostridium
)
Aerotolerant Anaerobes
: Tolerate oxygen (Example:
Lactobacillus
)
Microaerophiles
: Require low concentrations of oxygen (Example:
Campylobacter
)
View source
