Autotrophic CO(2) fixation by Chloroflexus aurantiacus: study of glyoxylate formation and assimilation via the 3hydroxypropionate cycle. J Bacteriol. 2001 Jul183(14):430516. 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. 
Comments 
For minimum generation time of 6 hours see BNID 105462 Table  link (pdf file, search for 'Chloroflexus', ref is beneath the table).
