|
these type of bacteria use organic compounds as a foodstuff/growth substrate.
|
heterotrophic bacteria
|
|
|
this is a common metabolite that serves as a growth substrate for heterotrophic bacteria
|
glucose
|
|
|
this is a hexose
|
glucose

respiration, fermentation, and anaerobic respiration
|
|
|
this process is the complete oxidation of glucose
|
respiration
|
|
|
this is an aerobic process
|
respiration

|
|
what is the terminal electron acceptor in respiration
|
O2
|
|
|

|
|
CH4 + 2O2 > CO2 + 2H2O + energy
|
methane oxidation
|
|
|
this is the incomplete oxidation of glucose

fermentation
|
|

in fermentation what are the end products formed
|
alcohol and acids
|
|
|
what are two types of fermentation mentioned in the book
|
lactic acid fermentation and alcoholic (ethanolic) fermentation
|
|
|
this involves the oxidation of glucose or the oxidation of organic acids
|
anaerobic respiration
|
|
|
this process occurs anaerobically and uses inorganic compounds

nitrate and sulfate
|
|
|
what else can anaerobic respiration use as a terminal electron acceptor
|
fumarate
|
|
|
organisms that use nitrate, sulfate, or fumarate instead of O2 as the terminal electron acceptor are
|
nitrate respirers, sulfate respirers, or fumarate respirers
|
|
|
what is another example of anaerobic respiration
