False
growth media is designed to simply support (and not restrict) microbial growth
T/F: Growth media is best suited for distinguishing between two similar species of
bacteria
Differential media
A researcher is asked to determine which of two vials contains E coli and which
contains salmonella. Knowing both are Gram-negative while only one of them is
capable of fermenting lactose, which type of media would be best suited?
A fastidious microbe is an organism with complex growth requirements and will
not grow without then. Enriched medias thus contain these specific and essential
nutrients required for the growth of a particular subset of microorganisms.
What are the requirements of a fastidious microbe?
