Arabinose Operon

Arabinose operon is the operon system found in the bacterial cell which is used to breakdown the arabinose. This kind of operon provides energy to the cell by the breakdown of arabinose into Xylulose phosphate. Arabinose provides energy in the form of a carbon source to the bacterial cell. The bacteria utilize this carbon source …

Isolation of Bacteria

Isolation of bacteria is a primary method to separate different groups of microorganisms. It is the method which helps us to differentiate different groups of organisms. It is the method, which allows us to discriminate different groups of bacteria on the basis of “Growth Pattern”. Different bacteria grow differently on the different nutrient medium based …

Mu Phage

Mu phage also refers as “Temperate or transposable phage” because Mu-phage causes transposition of the genes into the host cell, at the time of multiplication. It mainly attacks the members or species of enterobacteria family and that’s why also known as “Enterobacterial phage Mu”. The transposition of Mu-phage occurs by either of the two mechanisms: Replicative …

ELISA Test

ELISA test stands for Enzyme–Linked Immunosorbent Assay. It is a type of serological test and immunoassay technique. In the ELISA test, an enzyme links to the antibodies particularly to detect the presence of proteins like Antigens. The ELISA method was evolved from the RIA technique in the 1960s. Therefore ELISA technique is more or less …
