MODEL RELEASED. Bacterial contamination tests. Laboratory workers processing petri dishes being used to culture human tissue samples. Any bacteria or other micro-organisms found growing in the petri dishes will need to be identified. The worker in the background is examining a petri dish and making notes. If a growth in the petri dish needs to be investigated further,a sample can be placed in a new petri dish for further culturing and identification,a process called subculturing. The petri dishes contain nutrient media on which micro-organisms will grow if placed in the right conditions. The tissues being tested range from blood to bone | |
