Culture Media Ingredients

For any Bacterium to be made for any specific purpose , it is necessary to provide an appropriate biochemical and biophysical environment is made available as “CULTURE MEDIUM” based upon the special need of particular bacteria, a variety of culture media have been developed. The manner in which bacteria are cultivated and purpose of culture media vary widely. In some cases Liquid media is used and in some others Solid medium is found suitable. The usual gelling agent for solid or semi-solid medium is Agar Agar. Agar is used because of its unique physical properties an because its unique physical properties and because it cannot be metabolized by most bacteria . it is also relatively inert and holds nutrients that are in aqueous solution. Other ingredients are added depending on specific purpose.

propylene glycol LAB GRADE 75

Propylene glycol, also called propane-1,2-diol, is a synthetic organic compound with the chemical formula C3H8O2. It is a viscous colorless liquid which is nearly odorless but possesses a faintly sweet taste. Chemically it is classed as a diol and is miscible with a broad range of solvents, including water, acetone, and chloroform.

It is produced on a large scale and is primarily used in the production of polymers, but also sees use in food processing, and as a process fluid in low temperature heat exchange applications. In the European Union, it has the E-number E1520 for food applications.

The compound is sometimes called α-propylene glycol to distinguish it from the isomer propane-1,3-diol (β-propylene glycol).
