Growth rates of Candida tropicalis were studied in two different fermentors. One was the ordinary shaker flask containing both the aqueous culture medium and liquid hydrocarbons. The other was a specially designed rotating disk‐type fermentor containing only the aqueous culture medium, into which vapors of n‐paraffins from C 6 to C 18 were supplied continuously without forming the liquid hydrocarbon phase. The specific growth rates of Candida tropicalis in the rotating disk fermentor, under such conditions that supply of hydrocarbon vapor was sufficient, showed good agreement with those in the shaker flask. This seems to indicate that hydrocarbon uptake by Candida tropicals by direct contact with liquid hydrocarbon is negligible.
