What the Old Microbiologists Knew...

Abstract

Abstract Amazing is the fact that although the organisms have been known since the end of the seventeenth century, effective study of this group of organisms started after about 160 years, in the last two decades of the nineteenth century. The origins of science about bacteria were very difficult, there were many unknowns and conflict information. The research results provided by various scientists created complete chaos. From today’s perspective, it is difficult to imagine how it was possible, do research in such conditions, and obtain reliable results? Yet despite these difficulties, knowledge of our predecessors was neither so small nor so doubtful as might be supposed. On the contrary, it was surprisingly big and wide. What our predecessors knew about bacteria and especially their importance in nature? They knew that bacteria live everywhere, knew about their unlimited spread in the biosphere. The role of microorganisms in the mineralization of organic matter was known, as well as the circulation of matter in nature and role of bacteria in cycles of nutrient elements, and the solar energy as the driving force behind these changes. Today - although we understand these mechanisms much more accurately, we know a lot details and individual changes - but the basic outline of the functioning of the biosphere, valid until today created our predecessors. A look back at the beginning of the microbiology teaches us, how much can be achieved with seemingly primitive methods, if accompanied by a passion for research and imagination.
