An organism grew well on tsa plates, a bit slower on mm1 and not at all on mm1 without glucose. the results indicate that organism is not fastidious since it

Can grow on MM1.

Explanation:

Organisms that can only grow in a media having specific nutrients included in it are called a fastidious organism, this implies that these organisms have specific nutrient requirements for their growth. MM 1 represents the minimal media which has basic nutrients present in it, however as the fastidious organisms require some particular or complex nutrients for their growth they can not grow on the minimal media. Therefore, since the organisms that are given in the question is able to grow on the minimal media MM1, this implies that it is not a fastidious organism.
