Since two similar species of microbes are being studied they must be differen#ated under similar but just slightly different condi#ons (differen#al media).False 2 / 2 ptsQues!on 2A researcher is asked to determine if a sample contains Neisseria meningi!des.Knowing Neisseria meningi!desis slow growing and other foreign microbes may alsobe present in the culture, which type of media would be best suited?Selec#ve media Correct!Correct!Selec#ve media. If addi#onal foreign microbes may be present in your sample and you know Neisseria meningi#des is slow growing, you must restrict the unwanted microbes while suppor#ng the growth of Neisseria meningi#des. Thus, you are selec#vely encouraging one microbes growth, while selec#vely restric#ng others.Selec#ve and Differen#al media Differen#al media Growth media Your Answer:10 / 10 ptsQues!on 3What are the requirements of a fas#dious microbe?Essen#al nutrients for the growth of the microorganisms, they are organisms withabstract growth requirements, without these requirements they will not grow.Enriched Medias contains the specific and essen#al nutrients required for the growthof the subset of these microorganisms. Medias can be any combina#on of selec#ve,differen#al and enriched. A fas!dious microbe is an organism with complex growth requirements suchthat if absent it will not grow. Enriched medias thus contain these specific andessen!al nutrients required for the growth of a par!cular subset ofmicroorganisms.2 / 2 ptsQues!on 4True or False: LB agar is classified as a selec#ve, non-differen#al media.True False Correct!Correct!LB agar is the most basic type of agar and like LB media supports the growth of virtually all microbes without restric#on.Your Answer:5 / 5 ptsQues!on 5The polysaccharide-based hardening agent added to LB media to produce LB agar isderived from what?
