Incubation under carbon dioxide favoured development of the diphtheroid form, whereas aerobic incubation favoured the mycelial form. Iron depletion also induced filament formation. Although magnesium concentration directly affected the rate and amount of growth, no effect on morphology was observed. Critical concentrations of streptomycin sulphate and chloramphenicol also induced mycelium formation., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-38-1-125
