Why is direct selective or differential plating used for saureus testing rather than selective enrichment isolation?
Selective enrichment media are useful in recovering organisms which are in very low numbers, and they are often formulated like their corresponding isolation media.Selective enrichment will enhance their growth over competing bacteria,however undesired bacteria may grow.S.aureus grows poorly in the presence of others food microflora.By adding a selective agent to "poison" undesired organisms making the medium restrictive by including a nutrient only certain organisms can use or by leaving something out therefore direct selective or differential plating is more efficient to isolate s.aureus.Metabolically,it can utilize mannitol,which are not seen with other staphylococcal species.

Engineers increase the concentration of uranium-235 atoms in nuclear fuel during what process?
Enrichment
Enrichment of uranium faster with higher enrichment?
The higher enrichment needed the more enrichment and stripper stages needed. However the speed of enrichment depends more on how fast you can pump the uranium hexafloride through the individual stages without exceeding their limits. These limits will vary depending on enrichment technology used.
