The correct microbiological term for the sample of specimen that is put into a nutrient medium to produce a culture is:
a. Colony
b. Inoculum
c. Streak
d. Loop
Homework Answers
Inoculum is a small amount of test organism or culture added to media to get them in increase fold.
Inoculum develops into colony. Each colony is taken as a single organism in microbiology.
Streak is the process used to inoculate the organism and a loop is a material used to inoculate culture into a media
