Stamen Gigov Grigorov (Template:Lang-bg; October 27, 1878 – October 27, 1945) was a prominent Bulgarian physician and microbiologist. He discovered the Lactobacillus bulgaricus bacillus, which is the true cause for the existence of natural yogurt.

Life

Stamen Grigorov was born in the village of Studen Izvor [bg] (lit. "Cold Spring"), Tran, Pernik Province, Bulgaria. He completed his secondary education in natural sciences in Montpellier, France and medical science in Geneva, Switzerland. In 1905, at the age of 27, Grigorov made the discovery, for which he is best known. In the microbiological laboratory of Professor Léon Massol in Geneva, he discovered that a certain strain of bacillus is the true cause for the existence of natural yogurt.[1]

In recognition the strain was called by the scientific community Lactobacillus bulgaricus.

The original variety of Bulgarian yogurt can only be produced in Bulgaria and in some neighboring regions on the Balkan peninsula. In other natural climatic conditions the bacteria quickly degenerate, lose their qualities and die. An assistant professor of ethnology at the University of Plovdiv confirmed, that “the Balkans is one of the many places in the world which has the specific bacteria and temperature ranges needed to naturally produce yogurt." The unique blend of bacteria native to Bulgaria cannot be reproduced in other countries, so those that want to create their version of Bulgarian yogurt must constantly import new starter cultures.[2]

Apart from the discovery of Lactobacillus bulgaricus, Grigorov made a major contribution to the creation of a tuberculosis vaccine, along with Albert Calmette. On 20 December 1906, in Paris in issue No. 104 of the "La Presse Médicale" medical journal, his scientific report "The Anti-tuberculosis vaccine" was published, which informed the scientific community about the results of his research into the application of penicillin fungi for the treatment of tuberculosis. After the publication, the scientific community expressed serious interest in Grigorov's treatment. Through his scientific experiments "in-vitro" and "in-vivo" on lab animals and later on human patients, Grigorov clearly demonstrated and described the healing effect of penicillin fungi in the treatment of tuberculosis.[citation needed]

Legacy

On his 142nd birthday, his birthday was featured on Google Doodle, a Google art program which daily features ongoing events and undertakings, as well as their anniversaries.

Grigorov Glacier on Brabant Island in Palmer Archipelago, Antarctica is named after Stamen Grigorov.
