Degradation dynamics of acetate-fed (top) and propionate-fed (bottom) cultures subjected to different types of agitative motion: no motion (C, left), orbital shaking (Sh, middle), and magnetic stirring (St, right). Solid lines show the acetate concentration, while dashed lines show the propionate concentration (mM) and replicates are shown in different colours. For acetate-fed cultures, additional acetate (up to 50 mM) was added on day 111 and RNA extraction was performed on day 125. In the propionate-fed cultures, propionate was added on day 300 and RNA was extracted on day 338. Note the differing scales on the x-axes for acetate-fed and propionate-fed cultures
