The fatty acid composition of Dactylaria and Scolecobasidium

Abstract

The fatty acid composition of some thermotolerant strains of Dactylaria gallopava isolated from coal spoil tips has been compared with that of the type strain of D. gallopava, the original isolation of which was from diseased turkey poults. In addition, the fatty acids of the mesophilic fungi Dactylaria ampulliforme and Scolecobasidium spp. were analyzed. The scolecobasidia and D. gallopava had the same qualitative fatty acid pattern, though quantitatively there were differences, the scolecobasidia having more highly unsaturated lipids than D. gallopava. D. ampulliforme contained the triply unsaturated γ-linolenic acid and eicosatrienoic acid, and in this respect differed from the scolecobasidia and D. gallopava, which appeared unable to synthesize trienoic acids.

Host-Parasite Relations in a Mycoparasite IV. A Correlation between the Levels of g-Linolenic Acid and Parasitism of Piptocephalis virginiana

“…Shaw (1965) studied the fatty acids of phycomycetous fungi and observed that y-linolenic acid is a characteristic fatty acid of mucoraceous fungi, this fatty acid not being found in other classes of fungi. Recently though, y-linolenic acid has been found in two nonmucoraceous fungi (Sumner and Evans, 1971;Safe and Brewer, 1973). We investigated the fatty acid composition of Mycotypha microspora Fenner, highly susceptible to parasitism by P. virginiana (Berry, 1959).…”

A 48,XYYY Male: A Somatic and Psychiatric Description

“…Normal donors have been observed to produce 1 -26 % ofYY sperms (Sumner, Robinson, and Evans, 1971). Nondisjunction or anaphase lagging in a zygote so formed might be expected to produce a mosaic of 46,XY/48,XYYY cell lines.…”

Analytical Pyrolysis of the Fungal Melanins from Ochroconis spp. Isolated from Lascaux Cave, France

“…Fatty acids are synthesized by fungi [46]. Sumner and Evans [51] studied the fatty acids of Scolecobasidium spp. The old genus Scolecobasidium has been recently revised and most of its species have been transferred to the genus Ochroconis [52].…”

“…The old genus Scolecobasidium has been recently revised and most of its species have been transferred to the genus Ochroconis [52]. Sumner and Evans [51] reported that different Scolecobasidium spp. have the same fatty acid pattern, with hexadecanoic, octadecanoic, octadecenoic, and octadecadienoic acids, as major components and dodecanoic, tetradecanoic, hexadecenoic, and eicosanoic acids as minor components.…”
