11. The culture was isolated, grown in pure culture , and a subset of healthy turkeys was infected. 12. Lastly, the re-introduction of the bacteria grown in pure culture back into the host reestablished rhizoxin production. 13. This is a useful technique for pure culture of fungi, multicellular algae, and small metazoa, for example. 14. Viruses also require host cells to grow and reproduce and therefore cannot be grown in pure cultures . 15. P . Magnus is the most commonly isolated anaerobic cocci and is often recovered in pure culture . 16. Although some progress has been made, the former has not been achieved with the available pure cultures . 17. He was one of the first scientists to focus on the isolation of bacteria in pure culture . 18. Under aerobic conditions in soils or pure cultures , products of bromoxynil degradation often retain the original bromine groups. 19. Removal of the symbionts from the host degraded rhizoxin production and the symbionts were then grown in pure culture . 20. The wavelength of spectral emissions from the fungus grown in pure culture is in the range 470 640 m?.
