Analysis of fatty acid composition of anaerobic rumen fungi
Result description
The fatty acid (FA) composition of fresh mycelia of anaerobic rumen fungi was determined. The fatty acids methyl esters (FAME) of six strains belonging to four genera (Neocallimastix, Caecomyces, Orpinomyces, Anaeromyces) and one unknown strain were analysed by gas chromatography. All studied fungi posses the same FAs but differences were found in their relative concentrations. The FA profile of anaerobic fungi comprises carbon chains of length ranging from 12 to 24; the most common fatty acids were stearic (C18:0), arachidic (C20:0), heneicosanoic (C21:0), behenic (C22:0), tricosanoic (C23:0) and lignoceric (C24:0) with relative amount representing >4 % of total FA. Significant differences were determined for heptadecanoic, oleic, behenic and tricosanoic acids. Rumen anaerobic fungi can contain very long chain fatty acids; were found unsaturated fatty acids including cis-11-eicosenoic (C20:1), cis-11,14-eicosadienoic (C20:2), erucic (C22:1n9), cis-13,16-docosadienoic (C22:2) and nervo

Složení mastných kyselin u anaerobních bachorových hub
Czech description
V této studii byly sledovány rozdíly v profilu mastných kyselin u anaerobních bachorových hub. Bylo testováno šest zástupců náležejících k rodům Neocallimastix, Caecomyces, Orpinomyces, Anaeromyces a jeden dosud neidentifikovaný izolát. Jednotlivé testované vzorky vykazovaly stejné složení mastných kyselin, byl zaznamenán rozdíl v jejich relativních koncentracích. Byly detekovány mastné kyseliny s počtem uhlíků 12 ? 24; dominantními byly kyseliny stearová (C18:0), arachová (C20:0), heneikosanová (C21:0), behenová (C22:0), tricosanová (C23:0) and lignocerová (C24:0) s relativním zastoupením >4 % z celkových mastných kyselin. Bachorové anaerobní houby obsahují mastné kyseliny s větším počtem uhlíků; byly detekovány nenasycené kyseliny cis-11-eikosenová (C20:1), cis-11,14-eikosadienová (C20:2), eruková (C22:1n9), cis-13,16-dokosadienová (C22:2) a kyselina nervová (C24:1). Přítomnost těchto mastných kyselin se zdá být pro anaerobní houby specifická.
