Production of Ethylene by Penicillium Cyclopium

Abstract

Ethylene production by Penicillium cyclopium, ATCC No. 7615, was studied in relation to the life cycle of the fungus. Ethylene, >0.05ppm, was not produced until after the culture reached its maximum dry weight. When the sucrose concentration of the medium was varied, ethylene was proportional to growth. However, when the ammonium nitrate concentration was varied or the nitrogen source changed, there was no direct relationship. Inoculum size also influenced ethylene production. Ethanol markedly stimulated total ethylene production; dimedone was a good inhibitor of ethylene production. The structure of the naturally produced ethylene was verified by converting it to 1,2-dibromoethane and showing that its infrared spectrum was identical to that of authentic 1,2-dibromoethane.
