Aliphatic hydrocarbons of Cladosporium resinae cultured on glucose, glutamic acid, and hydrocarbons.
The carbon source markedly influenced the qualitative and quantitative composition of cellular hydrocarbons in Cladosporium resinae. Total lipid and hydrocarbon content was greater in cells grown on n-alkanes than in cells grown on glucose or glutamic acid. Glucose-grown cells contained a spectrum of aliphatic hydrocarbons from C(7) to C(36); pristane and n-hexadecane comprised 98% of the total. Cells grown on glutamic acid contained C(7) to C(23) hydrocarbons; n-tridecane, n-tetradecane, n-hexadecane, and pristane made up 74% of the total. n-Decane-grown cells yielded C(8) to C(32) compounds, and n-hexadecane (96%) was the major hydrocarbon. Cells grown on individual n-alkanes from C(11) to C(15) all contained C(11) to C(28) hydrocarbons, and cells grown on n-hexadecane contained C(11) to C(32) hydrocarbons. In n-undecane-grown cells, n-hexadecane and pristane made up 92% of the total, but in cells grown on C(12) to C(16)n-alkanes the major cellular hydrocarbon was the one on which the cells were grown. This suggests that cells cultured on n-alkanes of C(12) or longer accumulate n-alkanes prior to oxidizing them.
