Who is Stamen Grigorov? Stamen Grigorov Bio/Wiki

Stamen Gigov Grigorov was a famous physician and microbiologist from Bulgaria. Lactobacillus bulgaricus bacillus, which is the true cause of the life of natural yogurt, was discovered. He was born on October 27, 1878, in Studen Izvor, Bulgaria.

His birthday was featured on Google Doodle on his 142nd birthday, a Google art application that features ongoing activities and enterprises on a regular basis, as well as their anniversaries.


He was 67 years old.


Only in Bulgaria and in some neighboring regions on the Balkan peninsula can the original variety of Bulgarian yogurt be made. The bacteria rapidly degenerate, lose their characteristics, and die in other natural climatic conditions. An Assistant Professor of Ethnology at Plovdiv University stated 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.”

It is not possible to replicate a specific blend of bacteria native to Bulgaria in other countries, so those who want to create their version of Bulgarian yogurt must continuously import new starter cultures.

In addition to the discovery of Lactobacillus bulgaricus, Grigorov made a significant contribution to the development of an anti-tuberculosis vaccine (the vaccine at the Institut Pasteur de Lille is the main work of Albert Calmette and Camille Guérin). His experimental article ‘Anti-tuberculosis vaccine’ was published in Paris on 20 December 1906 in issue No. 104 of the medical journal ‘La Presse Médicale’ and told the experimental community about the findings of his studies on the application of penicillin fungi to the treatment of tuberculosis.

The science community expressed serious interest in Grigorov’s vaccine following the publication. Grigorov clearly illustrated and explained the healing effect of penicillin fungi in the treatment of tuberculosis through his experimental studies in ‘in-vitro’ and ‘in-vivo’ on laboratory animals and later on human patients.
