I te tau 1907, i huaina te huakita rite-tohu Bacillus bulgaricus (i tenei wa ko Lactobacillus delbrueckii subsp. bulgaricus). Ko te toa Nobel Russian me te koiora Ilya Mechnikov, mai i te Institut Pasteur i Paris, i whakaaweawehia e te mahi a Grigorov me te whakapae ko te kai auau o te yogurt te kawenga mo te roa o te oranga o nga kaiahuwhenua Bulgarian.
