Microbiology

Microbiology , study of microorganisms, or microbes, a diverse group of generally minute simple life-forms that include bacteria , archaea , algae , fungi , protozoa , and viruses. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities. The word microbe was coined in the last quarter of the 19th century to describe these organisms, all of which were thought to be related. As microbiology eventually developed into a specialized science, it was found that microbes are a very large group of extremely diverse organisms. Daily life is interwoven inextricably with microorganisms. In addition to populating both the inner and outer surfaces of the human body , microbes abound in the soil , in the seas, and in the air. Abundant, although usually unnoticed, microorganisms provide ample evidence of their presence—sometimes unfavourably, as when they cause decay of materials or spread diseases, and sometimes favourably, as when they ferment sugar to wine and beer , cause bread to rise, flavour cheeses, and produce valued products such as antibiotics and insulin.

Microbiology begins with the study of bacteria, yeasts, molds, viruses, and parasites - the microbes; how they are isolated, cultivated, and identified. The next level of study considers them as individual living systems, their physiology and genetics. The third level of study, the working level of a modern microbiologist, is concerned with how microbes interact with living and non-living elements and how these interactions may be controlled, modified, or expanded to benefit the environment and humanity.

Pre-microbiology, the possibility that microorganisms existed was discussed for many centuries before their actual discovery in the 17 th century. In his first century book, On Agriculture, Roman scholar Marcus Terentius Varro was the first known to suggest the possibility of disease spreading by yet unseen organisms. In , Girolamo Fracastoro proposed that epidemic diseases were caused by transferable seed-like entities that could transmit infection by direct or indirect contact, or even without contact over long distances. All these early claims about the existence of microorganisms were speculative and were not based on any data or science. Microorganisms were neither proven, observed, nor correctly and accurately described until the 17 th century.

Major contributions to the science of microbiology as a discipline in its modern sense have spanned the time from the midth century to the present day. The following is a list of prominent microbiologists who have made significant contributions to the study of microorganisms. Many of those listed have received a Nobel prize for their contributions to the field of microbiology. The others are typically considered historical figures whose work in microbiology had a notable impact in the field. Those microbiologists who currently work in the field have been excluded unless they have received recognition beyond that of being on the faculty in a college or university.
