Abstract: The invention provides an algae cultivation system and a process for cultivating algae. The algae cultivation system includes a conduit system having a first portion exposed to illumination and a second portion occluded from illumination that is capable of containing and moving a first type of algae, and a heat exchanger in thermal contact with the second portion of the conduit system. The algae cultivation system also includes a vertical conduit connected to the first portion of the conduit system and extending vertically upward from the first portion of the conduit system, a gas collection chamber communicating with an upper end region of the vertical conduit, and an algae processing unit that is capable of processing algae from the first portion of the conduit system, and that directs the extracted sugar, water and nutrients into the second portion of the conduit system to interact with the second type of algae therein.

Abstract: The invention provides a process for producing ammonia or ammonium from an organic material, the method by contacting the organic material with at least one hydrolytic enzyme, in a medium, to produce a medium including hydrolyzed or partially hydrolyzed organic material suitable for microbial fermentation. The hydrolyzed or partially hydrolyzed medium with organic material is then fermented in the presence of at least one microorganism capable of ammonification, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product that comprises ammonia or ammonium. The organic material includes nitrogenous compounds suitable for conversion to ammonia or ammonium.
