Solution- Heterotrophic bacteria are those that rely on other species for energy, while Archaebacteria are bacteria that lack a nucleus and are thus classified as prokaryotes.
Uses of heterotrophic bacteria–
- Lactobacillus is primarily used to make curd from milk.
- Rhizobium is a nitrogen-fixing bacteria found primarily in legume plants. These plants fix atmospheric nitrogen into ammonia, nitrates, and nitrites, which plants can use for growth and development.
- Microorganisms are useful in the food processing industry because they ferment the food and make it palatable.
- Microorganisms are also very valuable in the beverage industry, notably in the case of wine, where older fermented wine is in higher demand than new wine.
Uses of Archaebacteria–
These are anaerobes that make metabolic products such as methane and use these products as natural gas reservoirs, such as methanococcus.
- Some halophilic archaea are involved in economically significant activities such as biodegradation, bioremediation, and environmental processes.
- Enzymes found in some thermophilic archaea play a vital role in methane synthesis, metal leaching, and immobilized enzyme systems.
Note-Apart from its economic and industrial purposes, archaebacteria has biological significance, and it has more benefits than drawbacks. It lowers the PH of the skin, which reduces illness risk and makes us more protected.
