Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming, and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
An antibiotic is a type of antimicrobial substance active against bacteria.It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections.
John Elmer McKeen (1903 – 1978) was a pioneering chemical engineer known globally for his contributions to mass production of antibiotics, particularly penicillin, during World War II. His contributions led to the rapid scale-up of production, supplying a substantial portion of this vital "miracle antibiotic" to the armed forces. [ 1 ]
The medical application to industrial microbiology is the production of new drugs synthesized in a specific organism for medical purposes. Production of antibiotics is necessary for the treatment of many bacterial infections. Some natural occurring antibiotics and precursors, are produced through a process called fermentation. The ...
Production was ramped up to sixty million units per week by the time the plant was closed in March 1944; production shifted thereafter to a new plant that produced 300 million units per week. [ 147 ] [ 148 ] In 1947 ICI decided to construct a new plant to produce 32,000 litres (7,000 imp gal) of penicillin per day by the deep submergence method.
Cephalosporins are widely used antibiotics because of their clinical efficiency and desirable safety profile. [ 3 ] The cephalosporins are diverse in their antibacterial spectrum , water solubility , acid tolerability, oral bioavailability , biological half-life and other properties.
The production of a β-lactamase by a bacterium does not necessarily rule out all treatment options with β-lactam antibiotics. In some instances, β-lactam antibiotics may be co-administered with a β-lactamase inhibitor. For example, Augmentin (FGP) is made of amoxicillin (a β-lactam antibiotic) and clavulanic acid (a β-lactamase inhibitor).
The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic. Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing. However, these classifications are based on laboratory behavior.
