Abstract

n-Dodecane and fatty acids were good inducers of cytochrome P450 (CYP) and the ω-hydroxylase of lauric acid, which is a marker for ω-hydroxylation of n-alkanes, in Trichoderma harzianum. A cDNA, containing an ORF of 1520 bp, encoding a CYP52 of 520 amino acids, was isolated by RACE. Another n-alkane-inducible CYP was identified by LLC-MS/MS analysis of a microsomal protein band induced by n-dodecane in a library of T. harzianum. This suggests that T. harzianum has a CYP-dependent conversion of alkanes to fatty acids allowing their incorporation into lipids.

Abstract

The activity of CoO in solid solutions of CoO and MgO has been determined, in the temperature range 1273 to 1473 K, by an electrochemical method. The chemical potentials, activities, and activity coefficients of CoO and of MgO have been calculated. The mixtures exhibit slight positive deviations from ideal behavior.
