Cultivation of bacteria

Bacteria constitute a vital element in the ecology. They are essential to our health as well as the environmental health, play an essential role in the production of food, and offer bioengineers the tools to harness their abilities and produce compounds. However, they could also be harmful, causing harm and diseases. The capacity to cultivate the microbes that cause...

L-form bacteria Definition, Size and shape, Culturing , Applications

"L-form" bacteria are also referred to as L-phase bacteria or L-phase variants, and cell wall deficient (CWD) bacteria are bacteria with no cell walls. They were first identified around 1935, by the scientist Emmy Klieneberger Nobel who identified them as "L-forms" after the Lister Institute in London which she was working at.

Bacterial Culture Technique

Microbiological cultures, also known as Microbial cultureis the technique of generating microbial species by the process of letting them reproduce in a conditions in a monitored laboratory conditions. Microbiological cultures are fundamental and essential diagnostic methods that are employed as research tools within molecular biology. The term"culture" could be used to describe the microorganisms that are being grown.

Protoplast Culture Methods

Isolated protoplasts can be cultured in a liquid medium , or semisolid agar medium , either in thin layers or tiny drops of nutrient medium in petridish. The medium used to cultivate protoplasts is the same as that needed for suspension or callus culture.

Protoplasts fusion – Somatic fusion

The process of somatic fusion is also known as protoplast Fusion, is a kind of genetic modification of plants in which two plant species are merged into a hybrid plant that has the traits of both species the species, an somatic hybrid. Hybrids are created among different species that are of the exact same species (e.g. between non-flowering potato...

Protoplasts Isolation

The protoplast, sometimes referred to as a naked plant cell refers to all the constituents in a cell of plant that are not the wall of the cell. The term"protoplast" was first used in the work of Hanstein in 1880 to refer to the living matter contained within the membrane of the plant cell. The protoplast that is isolated...

Protoplasts Definition, Application and Protoplasts Culture

Protoplasts are plant cells that are completely naked with no cell wall however they do have plasma membranes and other components of the cell. They are functional cells, but without the presence of a barrier, cell wall. Protoplasts from various species can be merged to create a hybrid, and this is known as somatic hybridization (or protoplast fusion). Cybridization...

Sphaeroplasts Definition, Formation, Applications

A Spheroplast (or sphaeroplast according to British use) can be described as a microbe organism with a cell wall that is almost entirely gone through the penicillin or Lysozyme. According to certain definitions the term is employed to refer to Gram-negative bacteria. In other definitions, the word also includes yeasts. Spheroplast's name is derived in the sense that once...

Lipopolysaccharide (LPS) Structure, Functions

Lipopolysaccharides (LPS) are huge molecules that comprise the lipid and an O-antigen-based polysaccharide an outer core and an inner core that are joined via covalent bonds. They are located in the outer membranes of Gram-negative bacteria.

Archaebacteria Definition, Types, Characteristics, Structure, Examples

A unique characteristic of archaebacteria is their capacity to withstand extreme conditions which include very acidic, salty, and extremely hot environments. Archaebacteria have survived temperatures that reach 190 degrees Fahrenheit, which is just 22 degrees less than what is considered to be the water's boiling point and acids that are as high as 0.9 pH.

Structure of Gram-negative cell wall

Cell wall of the Gram-negative is more complicated than the Gram-positive cell wall. The amount of peptidoglycan present in the Gram-negative cell wall is considerably lower than that of that of the cell's Gram positive wall. There are only a few layers of peptidoglycan (2-8 millimeters) are visible in the cell membrane's outermost. A Gram-negative wall that lies outside...

Structure of Gram-positive cell wall

The cell's outer envelope is an organelle and physiological protection between the protoplasm (inside) of the cell and its external environment. The cell envelope guards bacteria from osmotic destruction and gives bacteria a rigid form. The cell envelope is composed of two elements that are a cell wall as well as a cytoplasmic or plasma membrane. It is a...

Factor affecting bacterial growth

In the context of human beings,"growth" is a reference to the increase in size; as an example changing from a tiny newborn to a huge adult. While bacteria can grow in size prior to the division of cells, growth in bacteria is a term used to describe increasing the amount of organisms, instead of the growth of their size.

Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. Because of the similarity of thinking and working with microorganisms other than bacteria, such as protozoa, fungi, and viruses, there has been a tendency for the field of bacteriology to extend as microbiology. The terms were formerly often used interchangeably. However, bacteriology can be classified as a distinct science.
