RESUMO
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 C7 to C36; pristane and n-hexadecane comprised 98% of the total. Cells grown on glutamic acid contained C7 to C23 hydrocarbons; n-tridecane, n-tetradecane, n-hexadecane, and pristane made up 74% of the total. n-Decane-grown cells yielded C8 to C32 compounds, and n-hexadecane (96%) was the major hydrocarbon. Cells grown on individual n-alkanes from C11 to C15 all contained C11 to C28 hydrocarbons, and cells grown on n-hexadecane contained C11 to C32 hydrocarbons. In n-undecane-grown cells, n-hexadecane and pristane made up 92% of the total, but in cells grown on C12 to C16 n-alkanes the major cellular hydrocarbon was the one on which the cells were grown. This suggests that cells cultured on n-alkanes of C12 or longer accumulate n-alkanes prior to oxidizing them.
