An essential oil (0.3percent v/w) was produced after fermentation of coconut for nine months by Chrysosporium xerophilum.Sixty per cent of the volatiles were aliphatic methyl ketones (C5-C13), esters and secondary alcohols whilst 38percent were present as free medium chain length fatty acids (C6-C12).A new class of ester, 2-heptyl esters of C8, C10 and C12 fatty acids, was identified by GC-MS and confirmed by synthesis.It is suggested that ester formation, ketone formation and alkane synthesis are mechanisms for removing medium chain fatty acids (C6-C12) which, if allowed to accumulate in the substrate, would be toxic to the fungus.Key Word Index - Cocos nucifera; Palmae; Chrysosporium xerophilum; fungus; substrate conversion coconut; methyl ketones; 2-heptyl esters; detoxification.

Solid-state crystallization achieves selective confinement of metal–organic framework (MOF) nanocrystals within mesoporous materials, thereby rendering active sites more accessible compared to the bulk-MOF and enhancing the chemical and mechanical stability of MOF nanocrystals. (Zr)UiO-66(NH2)/SiO2 hybrid materials were tested as efficient and reusable heterogeneous catalysts for the synthesis of steroid derivatives, outperforming the bulk (Zr)UiO-66(NH2) MOF. A clear correlation between the catalytic activity of the dispersed Zr sites present in the confined MOF, and the loading of the mesoporous SiO2, is demonstrated for steroid transformations.
