How antibiotic is made

The large-scale production of an antibiotic depends on a fermentation process. During fermentation, large amounts of the antibiotic-producing organism are grown. During fermentation, the organisms produce the antibiotic material, which can then be isolated for use as a drug.


Majority of the Hospital laboratories procure commercial antibiotic discs, while others either prepare their own discs or use both commercial and self-prepared discs 16 . The quality of paper used in the production of sensitivity discs is an important factor as the specification of these papers varies somewhat as to weight, thickness, texture, and absorbability of water, whichmay affects the ...

However, it took over a decade before penicillin was introduced as a treatment for bacterial infections 1930s: The first commercially available antibacterial was Prontosil, a sulfonamide developed by the German biochemist Gerhard Domagk.

Mechanical Engineering.: Manufacturing of brake disc

In most vehicles these brake discs (disc ring) are made of cast iron, which has good antiwear properties and it is cheap as well. But in certain other cases such as high performance vehicles, these brake discs are not up to their standards of high performance because the cast iron brake discs are heavy in weight and so reduces the vehicle''s performance to a particular extent.
