What Are The Examples Of Helpful Bacteria?

Microorganisms are omnipresent since they are able to survive in extreme climatic conditions. We have been learning and seeing the ill-effects of bacteria since ages, but are hardly aware of how beneficial bacteria can be. Good bacteria or beneficial bacteria are usually referred to as probiotics and are similar to the bacteria found in the human body. Probiotics are known to be beneficial to human health and in treating certain medical conditions.

Bacteria And Their Benefits

Listed below are few of the bacteria and their applications in various fields.

Rhizobium

  • It is a bacteria found in the soil which supplies ammonia to the plants, which is crucial for the growth of the plants.
  • Ammonia is an incredible nutrient source for the plants, but the amount of ammonia present in the atmosphere is not enough for the survival of the bacteria.
  • On the contrary, oxygen and nitrogen are present abundantly in the atmosphere. Hence the bacteria named rhizobium fulfils the nutrient requirement of plants by utilizing atmospheric oxygen to convert nitrogen into ammonia and the process is referred to as nitrogen fixation, thus enabling proper growth of the plants.
  • Hence microbes that belong to the class of Rhizobium are often referred to as nitrogen-fixing bacteria.

Streptomyces

The prescription antibiotics that is used to treat bacterial infections are produced using Streptomyces and hence these bacteria are often referred to as the ‘good bacteria’. Not just in the production of antibacterial agents, but the bacteria belonging to the class of Streptomyces are also used to produce antifungal agents and associated medicines, namely – immunosuppressants which are remedial measures prescribed by doctors for certain autoimmune diseases.

Lactobacillus Acidophilus

These bacteria are crucial in converting milk into curd. Dairy products like milk are exposed to the microbial activity of the Lactobacillus acidophilus bacteria in order to produce yoghurt. They are usually found residing in the human small intestine. Their presence in the system is not harmful, instead beneficial, as adequate amounts of these bacteria in the body hugely determines and is directly proportional to the amount of synthesis of Vitamin K and infection-fighting agents in the human body. The human body is likely more susceptible to infections when the count of Lactobacillus acidophilus falls below a normal range in the body. Consuming home-made yoghurt on a daily basis in a normal proportion is known to be the best way to stay away from infections.
