SUMMARY Species of Helicostylum, Rhizopus, Aspergillus, Penicillium and Fusarium can use as carbon source a fraction of n ‐alkanes containing mainly dodecane, tridecane and tetradecane. Yields of mycelium after 21 days were usually <2g/l but the addition of Brussels sprout blanching liquor increased the growth of the Aspergillus, Penicillium and Fusarium spp. 4‐ to 9‐fold. When Penicillium funiculosum and P. soppi were grown on the hydrocarbon fraction, 50% (w/w) of their total fatty acids had carbon chain lengths of < 16. When grown on sucrose the proportion was c. 2% (w/w). A culture of P. soppi grown on sucrose failed to produce short chain fatty acids when the n ‐alkanes were substituted as carbon source.
