Microbes are versatile. They possess the series of enzymatic machinery to bring out the biochemical changes inside as well outside the cell, thereby impacting the environment in which they are present.
The general awareness regarding microbes has greatly increased over the past few decades. However, little is known about their distant cousins, ‘Protozoans and Metazoans’, more popularly known as ‘higher life forms’. Both these categories of organisms are of great value to industrial effluent treatment. Microorganisms constitute 95% of population in an ideal activated sludge ,of which 4 % of this microbial population consist of higher life forms. Although these higher life forms contribute very little to the removal of organic nutrients, their presence however greatly enhances the clarity of the water and provides an indication of effluent condition (Eg. Toxicity,organic load, dissolved oxygen etc.).
“When one tugs at a single thing in nature, he finds it attached to the rest of the world”
We often wonder of the world beyond our skies, heavenly bodies and extra terrestrial life; but we seldom stop and think of the bountiful universe beneath our feet. We have this universe to thank, for the food we eat, the clean air we breathe, quite literally for our very existence. Along with organic matter, decaying material and inorganic components of the soil, are present billions of lively microbes that are responsible for the continuos replenishment of our soils.
