Generic Tips

  • Strains can grow on Tryptic Soy Broth plates (TSB) or TSB + Blood plates. There is no hemolysis on blood plates.
  • Strains are usually grown on Brain Heart Infusion (BHI).
  • Strain s-763 take 2 days to grow on plates from the freezer; please plan accordingly! Other strains take ~24 hours to grow.
  • SMUR is a low peptide liquid media used for transformation, BHI is used otherwise
  • Shaking is not needed. Notice that these cells have a more granular appearance, as they form tight clusters of cells.
  • Overnight cultures in BHI begin to die off; please do not plan on using them for more than the next day, if at all.
  • Less death is evident in SMSDM (S. mutans Semi-defined Media); same for BHI plates; we notice few cells surviving after 48 hours.
