Microbiology Branches, History, and Careers

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 vs gram negative bacteria differences in microbiology

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 …

Gram negative bacteria in microbiology examples, list, and structure

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 …

Gram positive bacteria in microbiology: examples and structure

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 …

Do bacteria have cell walls in microbiology?

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 …
