Methanogens are microorganisms that produce methane in absence of oxygen by the process called as methanogenesis. They belong to the kingdom Monera and the domain archaea. They use inorganic material as the source of energy such as hydrogen sulfide, elemental sulfur, ferrous iron, ammonia. They reduce carbon dioxide to methane and use hydrogen gas as an electron-donating reductant.

Clostridium bacteria is one of the most cause of food poisoning. It is a rod-shaped Gram-positive bacteria. It is a causative agent of botulism disease. It is a gas forming bacteria. It causes causative agent of botulism Gas gangrene by producing gas in tissues in gangrene.

Obligate anaerobes are organisms which grow in absence of oxygen. In presence of oxygen, they cannot survive. The example includes methane producing bacteria or methanogens.  They obtain their energy without consumption of oxygen. Other examples include Clostridium species.

Halophiles are organisms that thrive in high salt concentrations. They are also called as salt-loving microorganisms. Majority of halophiles belongs to Archaebacteria group. They are found in hypersaline environments like in arid, coastal, deep‐sea, underground salt mines. They can comfortably live in evaporation ponds or salt lakes, salt pans and salt marshes. 

There are three major known groups of Archaebacteria, namely methanogens, halophiles and thermophiles. Halophiles are organisms that thrive in high salt concentrations. Thermophiles are organisms that thrive extreme temperatures. Methanogens are organisms that produce methane gas.

Sambhar Salt Lake is India's largest inland salt lake. It is found in the city of Jaipur, state Rajasthan. Hence, the city is also known as Salt Lake City. The water in the lake comes from the rivers Mendha, Runpangarh, Khandel and Karian. 

Monera is non-nucleated unicellular organisms. They are prokaryotes. They have no membrane-bound organelles such as mitochondria, Golgi complex. They lack a true nucleus. Instead, they have nucleoid, genetic material without a nuclear membrane. Examples include Bacteria, Archaebacteria, Mycoplasma, Blue-Green algae. Out of these, the most primitive of monerans are Archaebacteria.

Marsh gas is also called as biogas. It is also called as methane gas as it primarily consists of methane gas along with hydrogen sulfide and carbon dioxide in minor composition. It is a produced by the decomposition of vegetable matter under water by anaerobic bacteria. Bacteria useful in biogas fermentation are Methanogens. They are found in marshes.

Archaebacteria are unicellular prokaryotic organisms. They include halophiles, thermophiles, methanogens. They are found in extreme habitats like areas with high salt concentration, extremely high temperature, marshy areas. They are non-photosynthetic bacteria. They are the oldest living beings. They are primitive organisms.
