      I already gave you the answer in the other thread. It’s beta-hemolytic streptococcus (provided that your previous post correctly identified hemolysis). Look at the links bellow:

      Lacking in the list of largely useless and wasted testing is the observation of hemolysis on sheep blood agar.

      usually 1 nm and higher. Size of atoms (C, N) is 70 pm and smaller. That’s 20-times less.

      However, you may be interested in the new one-molecule sequencing methods.

      And separation of chromosomes by dissection by laser is also nothing new.
