Methylotrophic Bacteria Flashcards
What do methylotrophs derive their energy from?
Organic compounds without C-C bonds, like CH3OH
Most methylotrophs are _______ ________.
obligate aerobes
Where are methylotrophs often found?
In the open ocean and soil; in plant roots and leaf surfaces
What does the Genus Hyphomicrobium do?
Its anaerobic using methanol coupled with denitrification
What do methanotrophs use for energy?
CH4
What does CH4 serve as in methanotrophs?
Serves as the electron donor and carbon source
What does methane monoxygenase do?
It breaks down CH4 to CO2
What kind of bacteria are methylotrophic bacteria?
Obligate aerobes
What is an example of a methanotroph?
Proteobacteria
What are the two types of proteobacteria?
Type I: Gammaproteobacteria
Type II: Alphaproteobacteria
What do methanotrophs get from being in soil?
Atmospheric methane
Describe methanotrophs in lakes and wetlands.
There is oxic interference with anoxic. There are also methanogens.
What kind of symbiosis with eukaryotes is seen in methanotrophs?
There is Mussel’s gill tissue and gas exchange with sea water.
Where are methanotrophs that are obligate anaerobes found and what do they do?
They’re found in black sea and reduce NO to obtain O2
