Microbiology (Greek word; micros “small” and bios “life”) is one of the most important branches of science which has been contributing to so many sectors like medical, soil, food, etc. Microbiology is a part of scientific study that deals with small organisms which can’t be seen by the naked eye …

Microbiology is an eminent subfield of biology. This sub-sector is concerned with organisms (that can only be seen through a microscope and cannot be seen with the naked eye), specifically microorganisms, their characteristics, functions, classifications, and methods to exploit and control their activities for human benefit. Microbiology began to flourish …

Bacteria (singular: bacterium) are microscopic unicellular organisms that thrive in a variety of environments. These organisms can live in the soil, in the ocean and in the human gut.

In 1977, Woese and his coworkers developed the groundbreaking three-domain system.  They proposed this classification based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (known as 16S rRNA). They created the first worldwide tree of …

Our living planet has a huge number of living organisms. We can’t know each of them properly without a proper format that going to direct us to know this variety and richness of organisms.

The sulfur cycle is the collection of processes by which sulfur moves between rocks, waterways and living systems. Such biogeochemical cycles are important in geology because they affect many minerals. Biochemical cycles are also important for life because sulfur is an essential element, being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in …
