Antibiotics manufacture

Benzylpenicillin is produced as various salts according to its intended use, whether as an input to semisynthetic /3-lactam antibiotics manufacture or for clinical use in its own right. 

All stages of antibiotic manufacture from fermentation through to finished product are governed by the code of good manufacturing practice (GMP), of whieh quality eontrol is one aspect. GMP requires that there should be a eomprehensive system, so designed, documented, implemented and controlled, and so furnished with personnel, equipment and other resourees as to provide assuranee that products will consistently be of a quality appropriate to their intended use. ... 

The product is extracted from the culture fluid by adsorption onto caibon or resins rather than by solvent. This illustrates an important general point that antibiotic manufacturing processes differ from one another much more in their product recovery stages than in their fermentation stages. Figure 7.4 illustrates a typical production ronte from inoculum to bulk antibiotic.

No single product can exemplify all the important features of antibiotic manufacture. Ben-zylpenicillin is a (3-lactam. Brief accounts are given of the manufacture of two other (3-lactams, penicillin V (phenoxymethylpenicillin) and cephalosporin C, to illustrate further key points. However, important as the (3-lactams are, they are but one of many families of antibiotics (Chapter 10). Furthermore, most industrial microorganisms used to make (3-lactams are fungi this is atypical of antibiotics as a whole where bacteria, particularly Streptomyces spp., predominate. Chapter 10 and some of the further reading at the end of this chapter provide the broad perspective, including information on those antibiotics made by total or partial chemical synthesis. 

Lincomycin hydrochloride formed a molybdenum blue heteropolycomplex with Folin s reagent This method was used to monitor lincomycin in the workplace air of antibiotic manufacturing plant at wavelength 600 nm (47).

The setting up of new biotechnology companies (Section 1.4.2) was the key event for the development of biopharmaceuticals based on recombinant technologies. Antibiotic manufacture had been established before this (Section 1.3). Antibiotics are still the most important strategy against bacterial infections. The world production of antibiotics is estimated at over 60000 tons per aimum, valued at more than 30 billion per year [128, 129]. For the synthesis of semisynthetic penicUlins and cephalosporins, the fermentation products penicillin G and cephalosporin, respectively, are hydrolyzed by immobilized enzymes to yield the acid form with the intact P-lactam ring as the active principal 6-APA, 7-ACA, or 7-aminodeacetoxy cephalosporanic acid (7-ADCA).
