Microbiology is essential because microorganisms are everywhere, they surround us, and they live with us. Thus, it is expedient that a study of this branch of biology is created. Therefore, in order to understand and dissect the study of microorganisms known as microbiology, it is imperative that a general insight be given. …
Gram positive and gram negative bacteria fall under the study of microbiology. The difference between gram positive vs gram negative bacteria is based on their staining color during the gram stain test. Using the gram staining technique, bacteria have been differentiated into gram-positive and gram-negative bacteria. The ability to differentiate bacterial cells …
Not all organisms are multicellular, some organisms exist as just a single cell and are called a single-celled organism or a unicellular organism. Cells come together to form multicellular organisms like plants and animals and that is why we call cells, the building blocks of life. However, in microbiology unicellular organisms are …
The Gram staining procedure in microbiology is a differential staining technique used to differentiate bacterial cells into gram-positive or gram-negative bacteria based on the differences in their cell wall components. At the end of the gram stain, gram negative bacteria stain pink/ red while gram positive bacteria stain purple or blue. Gram-negative …
The most common gram-positive bacteria examples in microbiology include Staphylococcus, Streptococcus, Bacillus, Clostridia, Listeria, and Corynebacterium. These gram-positive bacteria representative species are pathogenic and cause several diseases. All gram-positive bacterial cells are bounded by a single-unit lipid membrane. Generally, the cell walls of gram positive bacteria contain a 20-80 nm thick layer …
Definition In Microbiology Euglena can be defined as a known genus consisting of species of unicellular flagellates that exhibit both plant and animal characteristics. Even though, euglena share some characteristics of both plants and animals, they are not seen as plants or animals but as protists. They may be plant-like in that …
The gram stain procedure is a process that involves different steps, methods, or techniques. Gram staining results are used to differentiate bacteria as gram-positive or gram-negative. In microbiology, the gram stain procedure is one of the most crucial staining techniques. This gram staining technique helps in the diagnosis of a disease or …
Nevertheless, in microbiology the cell wall of bacteria is not like that of plants and other organisms due to the presence of peptidoglycan (also known as murein) which is located immediately outside the cell membrane. The bacteria cell wall is made up of peptidoglycan which makes the cell wall rigid and determines …
