Bacteria belongs to prokaryotes and hence it lacks nucleus and membrane bound organelle. But it has sufficient organelles that maintains and regulated important physiological, biochemical and molecular process. Invention of Electron microscope allowed us to explore the structure of bacteria. The bacteria has cell envelop (capsule, cell wall and cell membrane) envelop, nucleoid (DNA), ribosomes, […]

Archaebacteria are fascinating microbes and show diverse characteristics. They are unicellular and do not have nucleus and hence scientist thought to categorize them in prokaryotes. When further research was conducted the scientist found that they have few similarities to Eukaryotes. This created a puzzle in the field of classification. To solve the puzzle, the archaea

Endospore is the resistant form of bacteria which is very difficult to kill. Sporulation: Sporulation is a spore forming process in bacteria. Spores are metabolically inactive and resistant form of bacteria. The spore becomes resistant to chemical, heat, dehydration and radiation. The spores do not multiply. The bacteria with the ability of undergoing sporulation are

Flagella is the motility organelle of the bacteria. Introduction: Flagella is known as motility or locomotor organelle and it looks hair like appendage. They are longer than pilli and fimbriae. Their structure is rigid and slender. The bacteria are able to swim in liquid media is due to the rotating movement of flagella. To perceive

An aspiring and budding Microbiologist should always initiate their study by first understanding and learning Good Laboratory Practices (GLP). These Practices are general rules and regulations that every Microbiologist should follow in the lab. We are aware that Experiments are always associated with risks, but in case of Microbiology Experiments, the level of risk is

Microflora is nowadays being considered as a misnomer as the term Microbiota is becoming more common in parlance. Introduction to Presence of Microflora : It is known fact that microorganisms are ubiquitous, they present in air, water, soil and surface of animate and inanimate objects. When microbes are present in air, they are in the

Bacterial Motility is an important characteristic which is used to identify an unknown micro-organisms. The Hanging Drop technique helps to determine if the bacteria is motile or not. Introduction to Bacterial Motility Motility of bacteria is it’s ability to move by its own at expense of energy. The bacteria either swim or glide in the aqueous
