From 1925 on, she acted as the head of several microbiology and epidemiology institutes in Moscow. In 1925, Ermol'eva was appointed head of the Department of Microbial Biochemistry at the USSR Academy of Sciences. There, she began her research on bacteriophages and naturally-occurring antimicrobial agents—lysozyme in particular.
During the Second World War, she isolated a penicillin-producing strain of Penicillium crustosum. It was first used in Soviet hospitals in 1943. In 1942, she published the results of an experiment performed on herself, where she infected herself by drinking a solution of vibrio cholerae and recovered after treatment.
The results of her research were seen as essential in preventative measures against cholera in Russia's war efforts in the Eastern Front of World War II. In 1947, Ermol'eva became the director of the newly formed Institute of Antibiotics of the USSR Ministry of Public Health. From 1952 until her death, she headed the Department of Microbiology of the Central Post-Graduate Medical Institute in Moscow (now the Russian Medical Academy of Postgraduate Education). The "lively and realistic" depiction of Tatiana, the character based on Ermol'eva, popularized microbiology as a possible career among girls in the Soviet Union.
