The chemical composition of the secretions from the anal sacs of three species from the genus Genetta has been analysed by means of gas-liquid chromatography and mass spectrometry. The main constituents of the secretion are free fatty acids, hydrocarbons, mono- and diester waxes, triglycerides, alkane diols, and free alcohols. Composition of the secretion in the three species is fundamentally similar, but there are some remarkable quantitative differences of the components m entioned. Some of the alkane-1,2-diols in these secretions have never been found before in nature.

The chemical composition of the secretion from the anal sacs of a female of Civettictis civetta is analysed using gas- liquid chromatographical and mass spectrometrical tech­niques. The secretion mainly consists of cholesterol esters, monoester waxes, cholesterol, and free fatty acids of chain lengths not under C12; highly volatile components were not traceable. The functional significance of the anal sac secretion is discussed. `

Chain elongation of volatile fatty acids for medium chain fatty acids production (e.g. caproate) is an attractive approach to treat wastewater anaerobically and recover resource simultaneously. Undefined microbial consortia can be tailored to achieve chain elongation process with selective enrichment from anaerobic digestion sludge, which has advantages over pure culture approach for cost-efficient application. Whilst the metabolic pathway of the dominant caproate producer, Clostridium kluyveri, has been annotated, the role of other coexisting abundant microbiomes remained unclear. To this end, an ethanol-acetate fermentation inoculated with fresh digestion sludge at optimal conditions was conducted. Also, physiological study, thermodynamics and 16 S rRNA gene sequencing to elucidate the biological process by linking the system performance and dominant microbiomes were integrated. Results revealed a possible synergistic network in which C. kluyveri and three co-dominant species, Desulfovibrio vulgaris, Fusobacterium varium and Acetoanaerobium sticklandii coexisted. D. vulgaris and A. sticklandii (F. varium) were likely to boost the carboxylates chain elongation by stimulating ethanol oxidation and butyrate production through a syntrophic partnership with hydrogen (H2) serving as an electron messenger. This study unveils a synergistic microbial network to boost caproate production in mixed culture carboxylates chain elongation.

ООО «БИОТРОФ», Санкт-Петербург Аннотация: Приведены данные исследования методом газожидкостной хроматомасс-спектрометрии метаболитов, синтезируемых пробиотическими бактериями, входящими в состав кормовой добавки «Профорт®». Проведен опыт в условиях интенсивного промышленного птицеводства по применению кормовой добавки «Профорт®» (50 тыс. голов бройлеров в группе). Среди метаболитов пробиотических штаммов Enterococcus sp. и Bacillus sp. обнаружены такие полезные вещества, как молочная кислота, уксусная, пропионовая и другие короткоцепочечные (летучие) жирные кислоты, активные пептиды. Результаты зоотехнического опыта показали, что при скармливании бройлерам пробиотика «Профорт®» (500 г/т) живая масса при убое в 40 дней была выше контроля на 6,9%, конверсия корма улучшилась на 3,0%, а европейский индекс продуктивности бройлеров - на 5,69%.
