Inoculum:
Inoculation is a term often heard in microbiology, one of the branches of biology that deals with the study of microorganisms which includes unicellular organisms, viruses, and bacteria (Toppr, 2020). It is a process or technique that involves the transferring of microorganisms from culture for growth. Thus, in microbiology, the term inoculum refers to the material in which microbiologists used for inoculation, i.e., the introduction of microorganisms into a culture medium. The technique is commonly done using an inoculation needle (also called an inoculation loop). Inoculation is carried out to grow microorganisms in a culture medium under specific growth conditions.

I feel there may be a word missing in there somewhere, but a biologist may disagree. Inoculum was noted in this video. Try at about 1:25 if you’re impatient.
