Identified extracellular metabolites from metabolomic analysis on six different sample classes: C. glabrata planktonic and biofilm 24 h; S. epidermidis planktonic and biofilm 24 h; and dual-species C. glabrata/S. epidermidis biofilms 24 and 48 h.

RT represents retention time, RI represents Kovats retention index and TMS is the trimethylsilyl function, (CH3)3Si-. The array of digits in the column labelled “Coordinate” indicates ordinately the class membership of metabolites (C. glabrata planktonic = 1; S. epidermidis planktonic = 2; C. glabrata biofilm = 3; S. epidermidis biofilm = 4; dual-species biofilm 24 h = 5; dual-species biofilm 48 h = 6; 0 = not detected).

RT指保留时间（retention time），RI指科瓦茨保留指数（Kovats retention index），TMS为三甲基硅基（trimethylsilyl function，即(CH3)3Si-）。标注为"Coordinate"的列中的数字序列，依次表征代谢物的类别归属：光滑假丝酵母（C. glabrata）浮游态对应1；表皮葡萄球菌（S. epidermidis）浮游态对应2；光滑假丝酵母生物被膜对应3；表皮葡萄球菌生物被膜对应4；双物种生物被膜24小时对应5；双物种生物被膜48小时对应6；数值0代表未检出。
