A – Rhodococcus sp. IEGM 2296 cells after 7-d incubation in the presence of 0.1 % (v/v) n-hexadecane. Staining with a LIVE/DEADŽ BacLightTM Bacterial Viability Kit (Life Technologies, USA) differentiates between live (green) and dead (red) cells. B – R. cerastii IEGM 1243 cells after 3-d cultivation in the presence of ibuprofen (0.1 g/L). Staining with lipophilic Nile Red visualizes localization of lipid inclusions (arrows)
