The basic and most important step of a biochemical fermentation process is the preparation of a culture medium (nutrient broth). The production of a particular substance in large amounts should be the final result of those processes.

Of course, I've mentioned using aquarium antibiotics as a simple and relatively cheap way to get good quantities of various antibiotics. Since the only ingredient in these medications is the antibiotic itself, it's a perfectly reasonable alternative to begging your physician for a bunch of prescriptions.

Streptomycin and various other antibiotics are produced using strains of Streptomyces griseus. Spores of this actinomycete are inoculated into a medium to establish a culture with a high mycelial biomass for introduction into an inoculum tank, with subsequent use of the mycelial inoculum to initiate the fermentation process in the production tank.

The production of penicillin is a process that has changed dramatically since its beginnings. Opposed to what most people think, penicillin is used not only for treating colds but also serious diseases like Typhoid Fever, Syphilis, Pneumonia, Meningitis, Anthrax, Tetanus Tuberculosis, Chlamydia, Abscesses, Leptospirosis, Lyme disease.

• Like all antibiotics, penicillin is a secondary metabolite, so is only produced in the stationary phase. • What sort of fermenter does it require? It requires a batch fermenter, and a fed batch process is normally used to prolong the stationary period and so increase production.
