1.14.13.230 physiological function except for C1, strain BCP1 cells grow on the tested short-chain n-alkanes and show the lowest generation times with C3-C5 n-alkanes (2.7–2.8 h) 738517 1.14.13.230 physiological function inactivation of hydrolase alpha-subunit bmoX results in a mutant strain incapable of growth with butane, whereas growth with lactate, citrate or 1-butanol is normal. A low rate of ethylene oxidation is exhibited by the mutant strain independent of prior exposure to butane -, 739005
