In the 1980s, micropropagation technique was first tried to adopt a tank culture in conformation with fermentation technology, for example, for a perfume plantPelargonium graveolensat Kanebo Cosmetics in Japan. However, liquid culture never gained popularity because manufacturing cost was not expected to be lowered to guarantee successful commercialization; it is unlikely to increase the density of cultured shoots in a tank. Nowadays, micropropagation is used as a process for a rapidin vitromultiplication of shoots selected as the elite strains from the field, before getting them back to grow in the field.
