Many years later, the emergence and progression of the discipline of microbiology was able to resolve two important conundrums that had prevailed in science: the existence of spontaneous generation and the nature of infectious disease. Hundreds of electricity-generating bacteria found, including pathogenic, probiotic and fermenting bacteria. At the age of 16, he worked as a bookkeeper at a linen-draper's shop in Amsterdam. 15 Scientists Who Invented and Discovered Other Facts Related to Microorganisms Those scientists truly contribute a lot to the study of microbiology and medicine. Some strains however, such as Shiga toxin-producing E. coli (STEC), can cause severe foodborne disease. The newly discovered bacteria belong to the genus Paraburkholderia, which are known for their ability to degrade aromatic compounds and, in some species, the capacity to form root nodules that fix atmospheric nitrogen. The Royal Society team tested and thoroughly approved his observations.

He built a simple microscope during 1671 and started observing different substances. In simpler words, he discovered bacteria. In the late 1970s American microbiologist Carl Woese pioneered a major change in classification by placing all organisms into three domains—Eukarya, Bacteria (originally called Eubacteria), and Archaea (originally called Archaebacteria)—to reflect the three ancient lines of evolution.
