Rhodospirillum centenum

( \newcommand{\kernel}{\mathrm{null}\,}\)

Rhodospirillum rubrum is a purple nonsulfur bacterium that can grow aerobically or anaerobically. It has the ability to live through cellular respiration, fermentation, photosynthesis, or photoautotrophic growth.

Wild Type

  • Wild type PYP from Rhodospirillum centenum, pH 7.0, in 10mM phosphate buffer.
  • Absorption maximum: 434 nm,
  • Purity Index (A276/A434) = 0.40,
  • Total vol: 40μl (20μl/tube)
  • Total OD: 2.7, 200X dilution of sample= 0.33689 OD @ A434,
  • photocycle rate (time constant): ~50 seconds
  • R. centenum: The sample concentration @ 434nm is 63.38od/cm. To get 0.5 OD with 1 mm cuvette @434 nm, you will dilute ~127 times.
