beneficial uses of bacteria

Beneficial Mutations - Crop - Reported benefits after mutations Barley - Reduction in height, increased yield and day neutrality Groundnut - Improved oil content Wheat - Grain colour improved Rice - dwarfing, increased yield. In India, g induced mutations are carried out on seeds at Bhabh..

These are bacteria which live in a mutually beneficial association with other organisms. Such bacteria derive the essential nutrients from their host organisms and in that process help the host through some of their biological activities. 1. The most familiar example o..

The photoautotrophic bacteria possess photosynthetic pigments in membrane bound lamellae (or thylakoids) and utilise solar energy. The bacterial photosynthesis is different from that of green plants since here water is not used as a hydrogen donor. Hence oxygen is not release..

In 1884 a Danish physician Christian Gram devised a technique of differential staining for bacterial cells, using two simple stains. The procedure involves staining bacteria initially with a weak alkaline solution of gentian (crystalline) violet. All bacterial cells stain blue w..

The strong oxidizing action of chlorine destroys organic matter like bacteria, fungus and other micro-organisms. In most of the advanced countries chlorine has now been mostly replaced by ozone, which is more environment friendly disinfectan..

Ozone is used For air purification at the crowded places like cinema halls and tunnel railways. Due to its strong oxidizing power it also destroys the foul smell in slaughter houses. In sterilizing drinking water by oxidizing all germs and bacteria. For preservation of ..

Chlorine is used for bleaching cotton, linen, wood pulp, etc. It is used in the sterilization of drinking water, and the water in swimming pools. The strong oxidizing action of chlorine destroys organic matter like bacteria, fungus and other micro-organisms. In..

Plants on which we depend for food are under attack from insects, fungi, bacteria, viruses, rodents and other animals, and must compete with weeds for nutrients. To kill unwanted populations living in or on their crops, farmers use pesticides. The first widespread insecticide h..

Advantages - The offsprings are genetically identical and therefore advantageous traits can be preserved. Only one parent is required which eliminates the need for special mechanisms such as pollination, etc. It is faster. For example, bacteria can multiply every 20 minutes. This helps th..
