Design an experiment to solve the following problem:Determine the rate of methanogenesis (CO2 + 4H2 S CH4 +2H2O) in anoxic lake sediments and whether or not itis H2-limited.
Microbial Physiology
Microbial physiology is the branch of microbiology that is associated with studying the physiology of fungi, bacteria, and viruses. It is an important field of science concerning functional genomics and metabolic engineering.
Chemotaxis
The organism’s movement in a particular direction as a response to certain chemicals that are available in the environment is defined as chemotaxis. In brief, it can be defined as the occurrence of an organism’s movement in response to a certain chemical stimulus.
Design an experiment to solve the following problem:
Determine the rate of methanogenesis (CO2 + 4H2 S CH4 +
2H2O) in anoxic lake sediments and whether or not it
is H2-limited.
Methanogenesis is process of methane formation by methanogens (microorganisms can produce methane). Methanogenic organisms (for example, archaea) produce methane (CH4) from CO2. Heavy stable isotopes such as 13C and 15N are used to identify metabolically active microbial cells.
