The mold Neurospora crassa ATCC 5297a was grown in gaseous environments of helium, neon, argon, krypton, xenon, or nitrogen containing approximately 5 percent oxygen. A close correlation of the growth rate R (in millimeters per hour at 30°C) with the molecular weight MW of the chemically inert gas was observed. This correlation is described by the empirical equation: R = 3.88 - 0.1785 (MW).
