- Describe characteristics of Proteus Vulgaris in the Agar: (How does colonies look like (color) and explain does it grow on that agar. Blood Agar (Aerobic) MacConkey EMB PEA Mannitol Salt Agar Chocolate Agar Nutrient AgarWhy does uninoculated agar plates still has visible growth of microorganisms? Where do you think the microorganisms came from?What growth factor is often supplied for cultivation of fastidious bacterial pathogens?
- What culture medium can be used for the acclimatization of Bacillus and Pseudimonas to degrade phenol? It must be a nutrient-poor growing medium.What is the optimum growth temperature for most human pathogens? Explain.how can you use the unique characteristics of Listeria monocytogenes to produce a growth medium that is both selective and differential?
- why is it important that a small amount of inoculum be used in preparation of an agar slant?Why is a block of agar inoculated rather than streaking the fungal culture on a plate?Spores and toxin-producing microorganism produce toxins need higher Aw than minimum Aw for microbial growth. How could food industry benefit from this fact?
