Prosector
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Fine chemical
Further examples of modern drugs, where enzymes are used in the synthesis, are Pfizer’s Lipitor (atorvastatin), where the pivotal intermediate R-3-Hydroxy-4-cyanobutyrate is now made with a nitrilase, and Merck & Co.’s Singulair (montelukast), where the reduction of a ketone to S-alcohol, which had required stoichiometric amounts of expensive and moisture sensitive “(-)-DIP chloride” is now replaced by a ketoreductase enzyme catalyst step. Similar rewarding switches from chemical steps to enzymatic ones have also been achieved in steroid synthesis. Thus, it has been possible to reduce the number of steps required for the synthesis of Dexamethasone from bile from 28 to 15. Enzymes differ from chemical catalysts particularly with regard to stereoselectivity, regioselectivity, and chemoselectivity. They can also be modified (“reshuffled”) for specific reactions, for use in chemical synthesis. “Immobilized enzymes” are those fixed on solid supports. They can be recovered by filtration after completion of the reaction. Conventional plant equipment can be used with no, or only modest, adaptations. The "International Union of Biochemistry and Molecular Biology" (IUBMB) has developed a classification for enzymes. The main categories are Oxidoreductases, Transferases, Hydrolases, Lipases (subcategory), Lyases, Isomerases and Ligases, 
Companies specializing in making enzymes are Novozymes, Danisco (Genencor). Codexis is the leader in modifying enzymes to specific chemical reactions. 
The highest-volume chemicals made by biocatalysis are bio-ethanol (70 million metric tons), high-fructose corn syrup (2 million metric tons); acrylamide, 6-aminopenicillanic acid (APA), L-lysine and other amino acids, citric acid and niacinamide (all more than 10,000 metric tons).
