11. It is, thus, both autotrophic and heterotrophic. 12. Some sources divide the heterokonts into the autotrophic Ochrophyta and heterotrophic Bigyra and Pseudofungi. 13. "' Nitrification "'is the biological autotrophic bacteria and archaea. 14. This enzyme participates in the Calvin cycle which is an autotrophic carbon fixation pathway. 15. Chemotrophs can be either autotrophic or heterotrophic. 16. "' Methanothermobacter marburgensis "'is a thermophilic and obligately autotrophic archaeon. 17. Most chemolithotrophic organisms are also autotrophic . 18. Another well established pathway is via autotrophic denitrifying bacteria in the process termed the Anammox process. 19. However, SCP may also be produced entirely independent of agricultural waste products through autotrophic growth. 20. Until the 1990s, carboxysomes were thought to be an oddity confined to certain autotrophic bacteria.
