Abstract: | Summary In submerged culture there was negligible growth of Fusarium moniliforme with either n-tetradecane or gasoil (C13–C19) as the only carbon and energy source. In surface culture the cell yield was about 0.25 g dm–3 dry weight after four weeks incubation. Some oxidation products, mainly isomeric tetradecanones (4-one, 5-one, 6-one and 7-one), could be identified. However the cell yield in a trickle-flow column was about 3 g dm–3 dry weight after 7 days. Only traces of oxidation products could be detected. In a fixed-bed reactor, filled with glass rings, cell yields were similar to those in the trickle-flow column and depended on the medium flow rate.After termination of growth in the fixed-bed reactor, similar amounts of gibberellic acid were produced in a nitrogen-free medium with either gasoil or glucose. |
