Physiological properties and fatty acid composition in Mucor circinelloides f. circinelloides



Physiological properties and fatty acid composition in Mucor circinelloides f. circinelloides



Antonie van Leeuwenhoek 71(3): 201-206



Sporangiospores of Mucor circinelloides f. circinelloides CBS108.16 could germinate and grow on a wide variety of carbon sources in synthetic liquid media. Growth was supported by aldoses which have the same configuration at carbon atom number two as glucose. Di- and trisaccharides consisting of D-glucopyranosyl moieties were assimilated, while polysaccharides like inuline and starch were also utilised. Various alcohols and organic acids could be assimilated, while the phenolic compounds tested could not support aerobic growth. The fungus was able to ferment carbohydrates consisting of D-glucopyranosyl moieties, grow in the absence of vitamins and in the presence of cycloheximide. It also liquefied gelatin and produced lipases and cellulolytic enzymes. It was found that the highest percentages polyunsaturated fatty acids were produced when acetic acid, glucose, mannitol, soluble starch or trehalose was used as carbon source. The absence of vitamins in the medium lowered the percentage of these fatty acids.
