Ethylene is produced by cultivating aerobically a fungal strain capable of producing ethylenefrom α-ketoglutaric acid and, preferably, α-ketoglutaric acid from assimilable carbon sources, in the presence of L-arginine in a medium containing at least 20 ppm of divalent iron. A strain of Chaetomiun globosum, Phycomyces nitens, Paecilomyces carneus or Penicillium digitatum is employed in the examples as the fungal strain. |
