Yes, some marine bacteria and fungi have been identified to possess the capability to degrade agar agar. These microorganisms secrete enzymes such as agarases that breakdown agar into simpler sugars, which they can then use as a source of energy.
What is non-nutrient agar?
Non-nutrient agar is a type of agar medium that does not contain any nutrients suitable for supporting the growth of most bacteria.

Non-nutrient agar is generally used for the isolation and cultivation of these specific types of microorganisms.
Does Mycobacterium phlei grow on EMB agar?
Mycobacterium phlei is a non-fastidious organism that is commonly found in soil and water. It is not commonly grown on Eosin Methylene Blue (EMB) agar, as EMB agar is more selective for gram-negative enteric bacteria. Instead, Mycobacterium phlei is typically cultured on media specifically designed for mycobacteria, such as Middlebrook agar or Lowenstein-Jensen agar.

Because the peptone iron agar is used to detect ANAEROBIC bacteria. If you stab it deep into the agar you allow the bacteria to grow in the absence of oxygen. If you only inoculated the surface the bacteria wouldn't grow.
