Brooks G.F., Butel J.S and Morse S.A (2004). He also discovered viruses and sulphate-reducing bacteria. 7^th ed. In this early stage of his life, Winogradsky was "strictly devoted to the orthodox faith", though he later became irreligious.

He entered the Imperial Conservatoire of Music in St Petersburg in 1875 to study piano.

His studies of agricultural and industrial microbiology yielded fundamental discoveries in the field of biology. He is often incorrectly credited with framing the microbial ecology idea that "everything is everywhere, but, the environment selects", which was stated by Lourens Baas Becking.

Beijerinck was a socially eccentric figure.

History of microbiology. Advances in applied microbiology. Harley and Klein’s Microbiology. They both reported that microorganisms play important role in nutrient recycling in the ecosystem (particularly those of nitrogen, carbon and sulphur) as well as in the process of nitrogen-fixation by symbiotic or free-living soil bacteria.

Martinus Beijerinck showed in 1888 that some beneficial microbes in the soil (e.g.

San Diego: Academic Press.

Talaro, Kathleen P (2005). He later moved to the Polytechnic Institute in Delft, where he established the renowned Delft School of Microbiologists.

Throughout his career, Beijerinck made groundbreaking discoveries in the field of microbiology. In addition to having discovered a biochemical reaction vital to soil fertility and agriculture, Beijerinck revealed this archetypical example of symbiosis between plants and bacteria.

Beijerinck discovered the phenomenon of bacterial sulfate reduction, a form of anaerobic respiration.

In Encyclopedia of microbiology, vol. With the discovery of organisms that oxidized inorganic compounds such as hydrogen sulfide and ammonium as energy sources, autotrophs could be divided into two groups: photoautotrophs and chemoautotrophs.

Beijerinck began his work by studying the microorganisms that were present in and around plants, and he soon began experiments with microbes in the soil which led him to develop enrichment media for culturing microorganisms.

Before Beijerinck’s discovery of the enrichment media, microorganisms were previously were cultivated on medium consisting of potatoes or extracts of leftover animal renderings which supported the growth of many different bacteria, with chance and population density dictating what became dominant in the culture medium.

5^th edition. His low popularity with his students periodically depressed him, as he very much loved spreading his enthusiasm for biology in the classroom.

Beijerinckia (a genus of bacteria), Beijerinckiaceae (a family of Rhizobiales), and Beijerinck (crater) are named after him.
