[Formation of organic acids by the fungus Cladosporium resinae in media containing n-alkanes].
The so-called fungus Cladosporium resinae that often occurs in oil fuels ane increases their acidity grows well at the expense of n-alkanes from C11 to C16.  On the n-alkane containing media the fungus grows slowly and only under the stationary conditions.  During the fungal cultivation on the media containing n-dodecane or kerosene the culture liquid shows acetic acid and other fatty acids, ketoacids (pyruvic and alpha-ketoglutaric) as well as citric and isocitric acids that dominate among nonvolatile acids.  Upon nitrogen deficiency in the medium and comparatively good aeration the content of citric acids increases.  The culture liquid of the fungus devoid from the mycelium and nonutilized n-alkanes can be used a a nutrient medium for different microorganisms.
