Earliest life of single cell evolved into 3 branches having distinct traits. The branches further subdivide into more branches on the evolutionary tree of life called Phylogenetic tree of life. The first three branches are called Bacteria, archaea and Eucaryota. As we can see in this tree, there is a member of archaea family with the name Methanogen. This microbe holds the answer for presence of vast quantities of methane which is trapped inside the ice cages called methane hydrates. These hydrates are found in Earth’s in permafrost regions having very low temperatures or under the deep sea floor. Water… Read More »Is there life on Mars? Again Microbes hold the key
Bacteria can thrive on almost anything and adapt themselves to very diverse environments. They can subsist on substances like cellulose which we humans cannot assimilate. They can breakdown poisonous gases like hydrogen sulfide and absorb nitrogen from atmosphere and fix them into the roots of many plants which plants use as fertilizer. Bacteria can even breakdown crude oil. Crude oil consists of millions of hydrocarbons which are composed from carbon and hydrogen. These compounds range from the simplest molecule called methane made from 1 carbon atom to giant molecules containing even more than 50 carbon atoms. Many of these bacteria… Read More »Bacteria in Oilfields
Scientists speculate that all the fundamental particles were created from the energy immediately after the Big Bang event in which Universe was formed. Then these atoms combined in different permutations and combinations and molecules were born. Context of immediately in the cosmic events is not similar to the usual terms with which define our world. It may be millions of years. Earth was formed but its climate was not like the present day. There was no life except one algae namely “Blue Algae” known in the scientific language as “Cyanobacteria” where “Cyano” stands for blue color. It thrived in the… Read More »Simply Mind Boggling
There are trillions of microbes which inhabit an adult body. Looking at the sheer numbers, one may think that all these microbes are responsible for the ailments only. But this is not true. On the contrary, microbes are much more our friends than our enemies. Microbes run this world despite their infinitely small size. Their success lies in the sheer numbers and ability to adapt to the changing conditions. Following is the list of some species of the microbes that make our lives better: Bacillus thuringiensis A common soil bacterium that is a natural pest-killer in gardens and on crops.… Read More »Microbes Rule Our World
Microbes may be very small in size but their sheer numbers and remarkable adaptability to the existing climates is astounding. The word microbe is derived from micro-organisms meaning they are so small that they cannot be seen with naked eyes. A microscope is required to see them. But these tiny organisms are so active that they can bring about mammoth changes into the environment in which they live. Most of the chemical changes on the earth are brought about by these microorganisms. When the earth first formed, the atmosphere consisted only of carbon dioxide and water. Due to this iron… Read More »Mighty Microbes !!
