Biochemical tests

Biochemical tests are the tests that are used for the identification or confirmation of different bacterial species or different micro organisms based on the biochemical activities that the microorganisms are performing. In order to classify different bacteria as unique or different from each other we need to identify them as unique and to do their [...]

Bacterial Growth Curve

Bacterial growth Bacterial population growth studies require cultivation of viable cells in a fresh sterile broth medium and incubation in a closed culture vessel with a single batch of medium under optimum temperature, pH, and gaseous conditions. Under these conditions, the cells will reproduce rapidly and the dynamics of the microbial growth can be [...]

Blood Agar

Blood agar is an enriched medium used for isolation and cultivation of fastidious bacteria. Fastidious organisms, such as streptococci, do not grow well on ordinary growth media. Blood agar is also used to differentiate bacteria on the basis of their hemolytic properties, especially within the genera Streptococcus, Enterococcus, and Aerococcus. Principle Several species of Gram-positive [...]

Identification and characterization of bacteria

Bacteria are the complex group of living things. Bacteria consist of only one cell. There are thousands of species of bacteria, but all of them are basically one of three different shapes. Some are rod or stick shaped; others are shaped like little balls. Some bacteria can live in temperatures above the boiling point [...]

Sterilization

Sterilization refers to the killing or elimination of all microorganisms, including highly resistant bacterial spores. Sterilization is an absolute term, i.e. the objects must be sterile which means the absence of all microorganisms in that object. Sterilization can be referred to any process that removes all forms of life, including transmissible agents (such as [...]

Bacterial Capsule: Function, staining, procedure

Bacterial capsule A gelatinous layer of polysaccharide or polypeptide is called Glycocalyx. These polysaccharides may be composed of a single type of sugars (homopolysaccharide) or several types of sugars (heteropolysaccharides) and lies outside the cell envelope of bacteria. If glycocalyx is firmly attached to the cell wall it is referred to as a capsule. [...]

Plant mitochondrial electron transport chain

The electron transport chain consists of series of complexes, which take part in the flow of electrons. At each step of electron passage there is a loss of energy. Complex I-IV each plays a role in transporting electrons and establishing the proton gradient. The complexes further consist of oxidoreductases enzymes that have its cofactors [...]

Photoperiodism

In 1920, Garner and and Allard discovered the phenomenon of Photoperiodism in Maryland Mammoth plant. Photoperiodism is the effect of photoperiods or daily duration of light hours and dark periods on the growth and development of plants especially flowering. Plants can be divided into various categories depending on the basis of photoperiodic response to [...]

Stomatal movements

The stomata are tiny pores present in the epidermal surface of leaves, young stems and in certain fruits (banana, cucumber, etc.). They are also found in almost all the young aerial parts of the plant body. The different types of stomata are anomocytic type, anisocytic type, paracytic type, diacytic type and actinocytic type. Stomata [...]

Structure, function and mechanism of action of phytochromes

Structure, function and mechanism of phytochrome was discovered by Borth wick et al in 1952. Phytochromes are amorphous photoreceptors chromoprotein and are sensitive to red light. It is found in almost all eukaryotic plants and exists in two forms mainly cytosol associated Pr or P660 and membrane associated Pfr or P730. Pr absorbs light at [...]
