text: Yo, check it out, listen to this rap flow,
  I'ma drop some knowledge 'bout marine species, bro.
  Inadvertent transfer, dispersal, it's a mess,
  Ballast water shipping got us all stressed.
  
  Non-indigenous species causin' environmental strife,
  We need new treatments to save marine life.
  But the lack of indicators got us in a bind,
  Can't assess the effectiveness, that's what we find.
  
  Resistant dinoflagellate cysts, they might do the trick,
  But viability assessment's makin' us sick.
  So we developed a rapid method, hear me out,
  Staining with SYTOX Green, we got it all figured out.
  
  Flow-cytometric analysis, it's the key,
  Determining if the cysts are alive and free.
  The stain uptake, yo, it tells us the deal,
  Inversely proportional, that's the real deal.
  
  Flow cytometry and germination tests agree,
  In measuring viability, they're a harmony.
  But the flow-cytometric method got some perks,
  High precision and speed, it's how it works.
  
  Less than two days, we get the results quick,
  While germination takes weeks, that's the trick.
  So remember this method, it's the way to go,
  Protectin' marine life, that's the rap flow.
