The prevalence of cis-9-hexadecenoic acid is a specific feature of the fatty acid profile of zygomycetes from the order Kickxellales

The fatty acid profiles of zygomycetes from the family Kickxellaceae of the order Kickxellales were studied with reference to the species Kicksella alabastrina of the key genus Kicksella of the family and the species Linderina pennispora. When synthesized de novo, the lipids of these species show the prevalence of cis-9-hexadecenoic acid. This trait is stable and does not depend on cultivation conditions and can, therefore, be considered as a specific chemotaxonomic characteristic of fungi from the order Kickxellales. The fatty acid profiles of the two fungi under study are similar to that of sea buckthorn oil.
