If a bond has a 7% nominal yield or coupon and was purchased at a premium of $103 ($1030), then your YTM will calculate lower because the 7% interest is only paid to the $1000 par. The $30 premium does not earn interest and is not redeemable at par. So, a 7% bond at a premium is not really yielding 7% in that example.
E. coli is in the DOMAIN Eubacteria. 1  Kingdom: Prokaryotes (cells lacking nuceli). 2  Division or Phylum: Gracilicutes (with thinner cell walls-Gram negative, or appear red on a Gram stain).3  Class: Section 4 - Gram negative Rods and Cocci (shape of cells).. coli is in the DOMAIN Eubacteria. 1  Kingdom: Prokaryotes (cells lacking nuceli). 2  Division or Phylum: Gracilicutes (with thinner cell walls-Gram negative, or appear red on a Gram stain).
Genus of Escherichia: E. coli O157 is placed in this genus because it is mostly found in the human intestine but also present in soil and water. Species of Escherichia coli O157: This is one of the species that fall under the genus above.Throughout the site we will talk more about what makes this species unique.omain/Kingdom of Bacteria: E. Coli O157:H7 fits here because it is prokaryotic (meaning it has no nucleus, or membrane bound organelles), and unicellular. Phylum of Proteobacteria: The major characteristic that classifies E. coli O157:H7 is Gram negative meaning its outer membrane contains mostly lipopolysaccharides.
