“…Linoleic acid (18:2, ∆ 9,12 ) was detected in large amounts in both the mycelium and fruit body; however, free sterols were absent in the mycelium. Comparison of the composition of mycelia and fruit bodies concluded there are quantitative but no qualitative differences between the two (Byrne and Brennan 1975). The glycolipid fraction was composed of acylglucose, acylmannose, acyltrehalose, and glucosyloxy fatty acids whereas the phospholipid fraction was composed of phosphatidylethanolamine and phosphatidylserine; however, phosphatidylcholine found previously by Holtz and Schisler was absent (possibly the result of the occasional demethylation of phosphatidylcholine to phosphatidylethanolamine).…”

More than 30% of the neutral lipid fatty acids have a chain length of 18 carbons at least (Byrne and Brennan 1975).…”

Eight-carbon volatiles in mushrooms and fungi: properties, analysis, and biosynthesis

et al. 2006

View full text Add to dashboard Cite

Eight-carbon volatiles are ubiquitous among fungi and characteristic of the fungal aroma. They are the product of the oxidation and cleavage of the fatty acid linoleic acid and are classified as oxylipins, molecules taking part in a wide range of biological processes. Their involvement in the fungal aroma, interactions with pests and pathogens, and reproductive events are reviewed here, as well as the enzymic systems involved in their biosynthesis.

The lipid profile of Pleurotus sajor caju was studied in relation to mycelial and sporophore growth and different cultural factors. The growth was characterised by lipid synthesis during mycelial growth and utilisation during sporophore growth. The degree of unsaturation increased during mycelial growth and decreased during sporophore formation. The fatty acid composition of mycelium and sporophore was similar, linoleic acid (C,8.2) being the most dominant acid in both. C:N ratio had a significant (P<0.05) positive effect on mycelial dry weight; however, per cent total lipids was similar. Non-polar lipids became more unsaturated as the temperature was raised from 10" to 25°C and pH from 3.0 to 6.0, but declined when the cultures were aerated. Mycelial dry weight increased significantly (P<0.05) when the liquid medium was supplemented with lipids. In general, fatty acids with carbon chain length C,, and C,, stimulated the growth of mycelium. Supplementation of solid substrate (cotton seed hulls) with safflower oil, soybean oil or rice bran significantly (P<0.05) increased the yield of sporophores. Total lipids and ratio of non-polar to polar lipids were not affected by lipid supplementation.

“…1-Octen-3-ol is synthesized by the oxidation of fatty acid, which is then cleaved into short-chain volatiles (Combet et al, 2006). The most abundant fatty acid in both the mycelium and the fruiting body of the agaricomycete mushroom Agaricus bisporus, comprising 63%-74% of the total fatty acids, is linoleic acid (18:2, Δ 9,12 ), followed by palmitic acid and stearic acid (Byrne & Brennan, 1975;Combet et al, 2006).…”

Headspace solid‐phase microextraction gas chromatography–mass spectrometry for the detection of volatile organic compounds released from Ganoderma boninense and oil palm wood

Basal stem rot disease caused by the white‐rot fungus Ganoderma boninense is a major threat to the oil palm industry, and hence, the ability to detect infections at an early stage of development is desired. In this study, a headspace solid‐phase microextraction (HS‐SPME) method coupled with gas chromatography–mass spectrometry (GC‐MS) was employed to analyse the volatile organic compounds (VOCs) released from G. boninense cultures and infected oil palm wood. We examined VOCs released from three types of samples: G. boninense mycelium, oil palm wood and oil palm wood colonized by G. boninense. This preliminary study led to the tentative identification of 57 VOCs, including alcohols, alkanes, volatile acids, ketones, aldehydes, esters, sesquiterpenes and polycyclic aromatic hydrocarbon groups. Aliphatic compounds with eight‐carbon atoms, such as 1‐octen‐3‐ol, 3‐octanone, 1‐octanol and (E)‐2‐octenal, were the most abundant constituents of the Ganoderma samples, whereas furfural and hexanal were the major compounds detected in the oil palm wood samples. Chemometric analyses using cluster heat maps and principal component analyses were used to discriminate between the VOC profiles. The results indicated that the novel method described here could be used to detect Ganoderma disease and, more generally, for chemoecological studies of plant–pathogen interactions.
