Because the aim of biologists is to cultivate microorganisms or eukaryotic cells with no introduction of any extraneous organisms aseptic methods are essential for ensuring that experiments are conducted with precision and accuracy. Always keep in mind that a totally safe working environment for scientists does not exist.
Spread Plate Method in microbiology The spread plate method is used to isolate individual colonies from a diluted sample of mix population. Different methods have been developed for the isolation of microorganisms from a mixture sample but among them Spread plate culture method is the most widely used technique in laboratory. An ideal spread plate … Read more
The pour Plate Method technique was created in the laboratory by Robert Koch and is still widely used in the laboratory since his time. This technique is appropriate for Microaerophilic, facultative, or anaerobic microorganisms. It is straightforward to use, requires fewer resources, and is simple and cost-effective. However, it requires the specimen to be placed … Read more
Overview of Subculturing Technique In microbiology, subculture is defined as a new cell or microbiological culture, which is prepared by transferring a few or all cells to a fresh growth medium from an old culture or a previous culture. In a single word, the transfer of cells from a previous culture to a fresh or … Read more
Aim Transfer of microbial cells from a parent culture medium to a fresh broth culture. Principle The broth is a liquid medium, which is used to grown microorganisms within the laboratory on a small scale. It also used in an industrial fermentor on a large scale. The media called broths, milks, or nutrient solutions are … Read more
Streak Plate Method Overview There are two types of microbial culture such as mixed culture and pure culture. The mixed culture contains two or more species while the pure culture contains only a single species. During the identification of a microorganism, the first and important step is to isolate the individual species from a mixed … Read more

The White Blood Cells (WBCs) also known as Leucocytes are round nucleated cells in blood, that provide protection against foreign invaders. There are many types of White Blood cells found in blood, and identified as Granulocytes (Neutrophils, Eosinophils & Basophils) and Agranulocytes (Monocytes and Lymphocytes). The size of White Blood Cells can vary between 10 … Read more
