text: Yo, check it out, I got a tale to tell,
  'Bout bacterial strains from a paper mill,
  Isolated from water in the headbox,
  Two machines in Canada, where the flow rocks.
  
  Asticcacaulis, Acidovorax in the mix,
  Bacillus, Exiguobacterium, they don't miss,
  Hydrogenophaga, Pseudomonas too,
  Pseudoxanthomonas, Staphylococcus crew,
  Stenotrophomonas, they all came through.
  
  Their 16S rRNA genes revealed the truth,
  Forty-one strains, they were on the move.
  To determine their metabolism, we took a shot,
  Biolog EcoPlate showed what they got.
  
  Four metabolic groups, that's how we split,
  Analyzing their profiles, we didn't quit.
  In the headbox water, the bacteria thrive,
  Over a year, we watched them come alive.
  
  One compound stood tall, it didn't go down,
  2-hydroxybenzoic acid, it held its crown.
  But the other carbon sources, they were embraced,
  Utilized from 3% to a hundred, no waste.
  
  The bacterial communities, they stayed the same,
  Between the paper machines, no major change.
  But the sampling dates, they brought variety,
  Metabolic profiles shifted, that's the reality.
