Michiyo Tsujimura’s Professional Career
Her research career officially began when she entered Hokkaido Imperial University as a laboratory assistant in 1920. She worked in an unpaid position at the university’s Agricultural Chemistry Department’s Food Nutritional Laboratory because, at the time, the institution did not permit female students. Before moving on to the Medical Chemical Laboratory at the Medical College of Tokyo Imperial University in 1922, she researched silkworms’ nutrition there.
In October 1923, she transferred to RIKEN as a research student because the laboratory had been devastated by the Great Kant earthquake in 1923. She conducted nutritional chemistry research with Umetaro Suzuki, a doctor of agriculture. ,’s In 1924, Tsujimura and Seitaro Miura published an article titled “On Vitamin C in Green Tea” in the journal Bioscience, Biotechnology, and Biochemistry detailing their discovery of vitamin C in green tea. The export of green tea to North America increased due to this discovery.
Significant Advances In Agricultural Science
Michiyo’s studies in the US enabled her to develop several groundbreaking agricultural science findings. She discovered that specific bacteria and fungi might aid in enhancing the growth and yield of crops while also playing an important part in maintaining the health of the soil, which piqued her attention.
Her identification of a class of microbes called “actinomycetes,” which were found to create organic antibiotics that may shield plants from dangerous diseases, was one of her most important discoveries. The development of organic farming techniques was influenced by this discovery, which opened up new directions for the study of all-natural plant protection techniques.
She built on William Albrecht’s work by conducting significant research on the function of trace minerals in soil health. She discovered that certain trace minerals, like manganese and zinc, were crucial for plant productivity and growth and that shortages in these minerals could result in stunted growth and lower yields. Her studies contributed to a better understanding of the value of healthy soil and the requirement for careful management of agricultural lands.
