Biotransformation of M. aquatica essential oil by C. herbacea sex-specific gut microbial communities. M. aquatica essential oil was incubated with gut bacteria co-cultures from C. herbacea male and female individuals, and male (blue)- and female (red)-specific terpene profiles were determined by SBSE and GC-MS. Values are expressed as percentage increase/decrease with respect to the control without bacteria. Detected compounds: 1, ethyl acetate; 2, α-pinene; 3, 2,5-diethyltetrahydrofuran; 4, camphene; 5, β-myrcene; 6, δ-3-carene; 7, α-terpinene; 8, 2-heptanone; 9, (−)-limonene; 10, 1,8-cineole; 11, cis-β-ocimene; 12, γ-terpinene; 13, trans-β-ocimene; 14, 3-octanone; 15, p-ocimene; 16, α-terpinolene; 17, amyl isovalerate; 18, 3-nonanone; 19, 3-octanol; 20, all-trans-1,3,5-undecatriene; 21, 1-octen-3-ol; 22, 3-nonanol; 23, (−)-menthone; 24, (+)-menthofuran; 25, isomenthone; 26, β-bourbonene; 27, α-gurjunene; 28, L-linalool, 29, isopulegol; 30, isopulegone; 31, trans-β-caryophyllene; 32, 2-undecanone; 33, 4-terpineol; 34, menthol; 35, aromadendrene; 36, (+)-pulegone; 37, p-tolualdehyde; 38, α-humulene; 39, δ-terpineol; 40, α-amorphene; 41, guaia-9,11-diene; 42, α-terpineol; 43, borneol; 44, 4,7-dimethylbenzofuran; 45, δ-guaiene; 46, α-muurolene; 47, piperitone; 48, δ-cadinene; 49, γ-cadinene; 50, cis-p-mentha-2,8-dien-1-ol; 51, dihydro-agarofuran; 52, α-cadinene; 53, 2-tridecanone; 54, p-menth-1-en-9-ol; 55, cis-5-decen-1-yl acetate; 56, p-menth-1(7)-en-9-ol; 57, 2-tridecanol; 58, palustrol; 59, cis-jasmone; 60, 1-dodecanol; 61, dodecyl acrylate; 62, ledol; 63, caryophyllene alcohol; 64, cubenol; 65, fonenol; 66, globulol; 67, viridiflorol; 68, rosifoliol; 69, 5-guaiene-11-ol; 70, spathulenol; 71, cedrol; 72, longipinanol; 73, τ-cadinol; 74, carvacrol; 75, δ-cadinol; 76, α-cadinol; 77, mint furanone 2.
