8
nonpathogenic, free-living bacteria which uses solar energy or carbon dioxide as sole source of carbon to prepare its own food
Autotrophs
8
they gain energy from oxidation of chemical compound and reduces inorganic compounds such as NH3 as electron source.
Chemolithotrophs
9
they gain energy from chemical compounds and uses organic compound such as glucose and amino acids as source of electron.
Chemoorganotrophs
9
Autotrophs two type subdivision on the basis of energy utilization to assimilate carbon dioxide.
Photoautotrophs and Chemoautotrophs
10
they utilized light to assimilate carbon dioxide.
Photoautotrophs
11
Photoautotrophs two group on the basis of electron source
Photolithotropic autotrophs and Photoorganotropic autotrophs
12
they utilize chemical energy for assimilation of carbon dioxide.
Chemoautotrophs
13
bacteria which uses organic compound as carbon source and lack the ability to
Heterotrophs
14
bacteria that can grow even between 0°C to 30°C but optimum
Psychrotrophs (facultative psychrophiles)
14
Classification According to optimum temperature requirement
Psychrophiles Psychrotrophs Mesophiles Thermophiles Hyperthermophiles
15
bacteria that best grow above 45°C, contains saturated fatty acids in their cell membrane so their cell membrane does not become too fluid even at higher temperature, can survive pasteurization temp
Thermophiles
15
bacteria that can grow at below 0°C to 20°C but the optimum temperature of growth is 15°C or below. It contains polyunsaturated fatty acids in their cell membrane which allows it to not freeze even at lower temperature hence it is a common contaminant in refrigerators.
Psychrophiles
15
bacteria that can grow best between 25-40°C and optimum temperature for growth is 37°C
Mesophiles
16
capable of growing in mesophilic range
Facultative thermophiles
17
true thermophiles or Stenothermophiles
Obligate Thermophiles
18
bacteria that have optimum temperature of growth above 80°C
Hyperthermophiles
19
Classification according to optimal pH for growth
Acidophiles Alkaliphiles Neutrophiles
19
bacteria that grows best at alkaline
Alkaliphiles
20
bacteria that grows best at acid
Acidophiles
21
bacteria that requires and cannot grow in the absence of oxygen
Obligate Aerobes
21
bacteria that does not require NaCl but can tolerate low concentration of NaCl in growth medi
Halotolerant
21
bacteria that grows best at neutral pH (6.5-7.5)
Neutrophiles
21
bacteria that require high concentration of sodium chloride (NaCl) for growth.
Halophiles
21
Classification According to salt requirement
Halophiles and Halotolerant
21
Classification According to gaseous requirements
Obligate aerobes Facultative anaerobes Aerotolerant anaerobes Microaerophiles Obligate anaerobes Capnophiles
22
bacteria that do not require oxygen but can use it if available
Facultative Anaerobes
23
bacteria that do not require but can tolerate the presence of oxygen for growth
aerotolerant Anaerobes
24
bacteria that do not require but can tolerate low concentration of oxygen for growth
Microaerophiles
25
bacteria that require carbon dioxide for growth
Capnophiles
25
bacteria that can grow only in absence of oxygen
Obligate anaerobes
25
Classification according to cell wall
Gram positive bacteria and Gram negative Bacteria
26
cell wall of these bacteria is composed of peptidoglycan layer only. The cell wall retains the crystal fire lit or gram stain which appear violate in gram staining.
Gram Positive Bacteria
27
Classification according to flagella
Monotrichous Lophotrichous Amphitrichous Peritrichous Atrichous
27
cell wall of these bacteria is composed of Peptidoglycan and outer membrane. The cell wall does not retain the gram stain, but they take up the red color of the counter stain during Gram staining.
Gram Negative Bacteria
27
bacteria with single flagellum in one end of cell.
Monotrichous
27
bacteria having bundle of flagella in one end of cell.
Lophotrichous
27
bacteria having single or cluster of flagella at both end of cell.
Amphitrichous
28
Bacteria without flagella
Atrichous
28
Bacteria having flagella evenly distributed around the cell surface.
Peritrichous
28
Classification according to sphere
Spore forming bacteria and Non-spore forming bacteria
29
produce spore during unfavorable condition
Spore forming bacteria
30
Spore forming bacteria subdivided into two groups:
endospore forming bacteria and exospore forming bacteria
31
spore produced within the bacterial cell.
endospore forming bacteria
31
spore produced outside the cell
exospore forming bacteria
32
those bacteria which do not produce spore
Non-spore forming bacteria
