NUTRITIONAL / TYPES OF BACTERIA

1. All organisms
AUTOTROPHS
HETEROTROPHS
PHOTOAUTOTROPHS
They use light as a source of energy
and electron donors are H2O, H2S, S
and other sulphur containing
inorganic compounds
(SOURCE OF CARBON IS
CARBON DIOXIDE CO2)
(SOURCE OF CARBON ARE
ORGANIC COMPOUNDS MADE
BY OTHER ORGANISMS)
GREEN SULPHUR
BACTERIA
PURPLE SULPHUR
BACTERIA
Carbon Source
Source of energy is light
e.g. Purple nonsulphur
bacteria
PHOTOHETERO
TROPHS
CHEMOHETERO
TROPHS
These bacteria obtain their
energy by breaking down
organic compounds
PARASITIC
SAPROPHYTIC
SYMBIOTIC
CHEMOAUTOTROPHS
They are oxidizable inorganic
substance such as H2, H2S, Fe2, Mn2,
NO2, NH4 elemental sulphur as sole
source of energy
NITRIFYING
