As opposed to the their counterparts in the laboratory which can create optimum conditions like high temperature and pressure required for the reactions, they do the same synthesis under the prevailing conditions using enzymes which they synthesize in the first place. Then there are others… Read More »Bacteria and Plants: Master Chemists
