11. It was isolated from the root nodules of the plant " Lebeckia ambigua ". 12. Larvae are found on fresh and decaying vegetation, carrion, human corpses, and root nodules . 13. Within the root nodules , rhizobia fix atmospheric nitrogen into ammonia using the nitrogenase enzyme. 14. Bacteria perform nitrogen fixation, dwelling inside root nodules of certain plants ( legumes ). 15. Like other legumes, they can rhizobium root nodule symbiosis, fertilizing the soil for other plants. 16. During his career Bisseling has done research on the symbiosis between root nodules and rhizobia bacteria. 17. Some " Dryas " plants have root nodules that host the nitrogen-fixing bacterium " Frankia ". 18. The root nodule formation by " Sinorhizobium meliloti " is apparently dependent on the flavonoids pathway. 19. Bacteria of this genus also form root nodules . 20. ""'Mesorhizobium hawassense " "'is a bacterium from the genus of Mesorhizobium which was isolated from root nodules .
