Bioremediation - Definition, Types, Application

What is Bioremediation? Bioremediation is a process used to clean up and detoxify polluted sites by utilizing microorganisms, plants, or their enzymes to break down and degrade environmental contaminants. It involves the natural or deliberate introduction of these biological agents to enhance the rate of degradation and transformation of pollutants. The concept of bioremediation includes … Read more

Microbe-Plant interaction – Types, Examples

Microbe-Plant interaction - Types, Examples

Microbe-Plant interaction Plants are immobile, but they are continuously subjected to both biotic and abiotic stress. Constant warfare exists between harmful microorganisms and the host plant, with the outcome determining resistance or disease. Plants exude a variety of organic substances, resulting in a nutrient-rich environment that is conducive to microbial growth. Therefore, plants are highly … Read more

Nitrogen Fixation – Definition, Importance, Processes

Nitrogen Fixation - Definition, Importance, Processes

What is Nitrogen Fixation? Nitrogen fixation is the fundamental biological process and the first step in the nitrogen cycle. Certain bacterial species, such as Rhizobium, Azotobacter, etc., and other natural phenomena convert atmospheric nitrogen into ammonia (another type of nitrogen) throughout this process. Why is Nitrogen Fixation Necessary? It serves the following functions in nature: … Read more
