Physical Parameters for Growth of Bacteria

Physical Parameters for Growth of Bacteria Aside from the kind of media used to support bacterial growth, a number of environmental physical factors are crucial for the best possible growth. Every kind of microorganism needs to have its physical characteristics investigated. Temperature, pH, oxygen, light, hydrostatic pressure, and other factors are a few of these … Read more

Nutritional Requirements of Bacteria

For growth and multiplication, bacteria need adequate nutrition, optimum pH, temperature and oxygen. Microorganisms have been cultivated in laboratories using appropriate artificial media that contain sources of carbon, nitrogen, hydrogen, oxygen, phosphorous, and other elements in very small quantities, such as sodium, potassium, magnesium, and iron. Bacteria can be classified depending on nutritional requirements such … Read more

Introduction to Prokaryotes and Eukaryotes

All living organisms, including microorganisms, are classified as either prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished by their cellular characteristics. Prokaryotic cells lack nuclei and organelles, whereas eukaryotic cells contain both. Prokaryotic and eukaryotic cells share a number of characteristics. Both kinds of cells use DNA to store their genetic information and are surrounded … Read more

Ultrastructure of Bacteria and Its Morphological Classification

Introduction Bacteria are unicellular, free living, microscopic microorganisms capable of performing all the essential functions of life. Bacteria possess both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Bacteria are prokaryotic microorganisms that do not contain chlorophyll. They found in water, soil, air, food and all natural environments. In this article we will see the ultrastructure … Read more

Microbiology- Definition, History, Types of microorganisms, Branches of microbiology, Scope of microbiology

What is microbiology? Microbiology is the branch of science which deals with study of microorganisms, which are invisible to naked eyes. It studies the function, structure and economic importance of living organisms. Some microbes are helpful to human beings and some are harmful. Study of microbes plays an important role in medical sector to analyse … Read more
