Autotrophic CO(2) fixation by Chloroflexus aurantiacus: study of glyoxylate formation and assimilation via the 3-hydroxypropionate cycle. J Bacteriol. 2001 Jul183(14):4305-16. p. 4314, right column, 1st paragraphPubMed ID11418572
Method The CO2 fixation rate for growing cells was estimated from the equation dS/dt=(µ/y)x, correlating substrate S (moles of inorganic carbon) consumption per time (t) unit (minute) with the specific growth rate µ, the molar growth yield y, and the dry cell mass x of the culture. A generation time of 26h corresponds to a µ of 0.00044min^-1, y is 24 g of dry cell mass formed per mol of CO2 assimilated (assuming 50% of dry cell mass is carbon), and x is 1 g of dry cell mass, corresponding to 500 mg of total cell protein. Generation time calculated from G=ln2/k where G is the generation time and k is the growth rate.
