Determination of the major compounds in the extract of the subterranean termite Macrotermes gilvus Hagen digestive tract by GC-MS method / N. Subekti [et al.] // The Ukrainian Biochemical Journal. - 2017. - Том 89, N 4. - P77-82 MeSH-головна: ТЕРМИТЫ -- ISOPTERA (патогенность) ЖЕЛУДОЧНО-КИШЕЧНЫЙ ТРАКТ -- GASTROINTESTINAL TRACT (патофизиология) Анотація: Degradation of woody components by termites is associated with symbionts inside their digestive tract. In this study, the major compounds were determined in the extract of the termite guts by GC-MS method. Macrotermes gilvus Hagen (worker caste) termites were collected and their dissected guts underwent methanol extraction. It was found that the gut of the termites has an alkaline environment (pH 8.83 ± 0.31) that supports the digestion of lignocellulose biomass and also helps to solubilize phenolic and recalcitrant compounds resul­ting from the depolymerization of woody components. The GC-MS analysis showed that termite guts contained hydrophobic organosilicon components including dodecamethylcyclohexasiloxane, tetradecamethylcyclohexa­siloxane, hexadecamethylcyclooctasiloxane, and octasiloxane, 1,1,3,3,5,5,7,7,9,9,11,11,13,13,15,15-hexa­decamethyl. The guts also contained a phytosterol, which was identified as β-sitosterol. Further analysis of these water-insoluble compounds is needed to reveal their importance in termite digestion Дод.точки доступу: Subekti, N. Fibriana, F. Widyaningrum, P. Adfa, M. Вільних прим. немає
