Microalgae autotrophic

As nonconservative gases, carbon dioxide and oxygen are closely coupled to the organic carbon pool through autotrophic (e.g., photosynthesis) and heterotrophic (e.g., respiration) processes. The dominant primary producers in estuaries and the coastal ocean are benthic and pelagic microalgae (phytoplankton). The average atomic C-to-N-to-P ratio...

Autotrophic microalgae as well as heterotrophic yeasts, bacteria, and fungi impH-cate limitations for a commerdal SCOs production process. An overview is hsted in Table 5.12. The main reasons are the costly downstream process of the SCOs and the high costs of carbon sources for heterotrophic microorganisms.

Microalgae are able to get energy from different metabolisms (Richmond and Qian 2004). In autotrophic metabolism, in the presence of light, organisms are able to convert CO2 and water into biomass. Already heterotrophic systems are a different approach to microalgal biomass production with elimination of light requirement and CO2 absorption. 

Autotrophic and heterotrophic microalgae have different growth reqnirements. Autotrophic microalgae have an absolute requirement for light for photosynthesis and may...
