A system and method for the production of microbial consortiums and by-product material is provided. A physical containment system comprising phase spaces arranged in a discrete order to favor specific biological reactions is also provided. Phase profiles and phase data sets include the pre-determined physical and biological parameters for the phase space transitions. Movement of material from one phase to the next is hydraulically balanced enabling working fluid to continuously move in a fixed direction and rate of flow. Continuous monitoring of phase profiles and phase data sets provide feedback to the system enabling alteration of the conditions in the system to control reactions therein.

A method for recovering sulfur within a gas processing system is described herein. The method includes contacting a natural gas stream including an acid gas with a solvent stream within a co-current contacting system to produce a sweetened natural gas stream and a rich solvent stream including an absorbed acid gas. The method also includes removing the absorbed acid gas from the rich solvent stream within a regenerator to produce a concentrated acid gas stream and a lean solvent stream. The method further includes recovering elemental sulfur from hydrogen sulfide (H.sub.2S) within the concentrated acid gas stream via a sulfur recovery unit.

A method of fixating and stabilizing nitric oxide metabolites within fermented natural substance according to an embodiment of the present disclosure includes adding a fermentative strain to nitrogen-containing natural substance and carrying out fermentation. The fermentation efficiency is maximized by optimizing the fermentation conditions so that the productivity of nitric oxide metabolites is significantly improved. Thus, eating a fermented natural substance in which nitric oxide metabolites are fixated and stabilized by the method of the present invention would be helpful for maintaining the homeostasis of human body, in which nitric oxide synthase is either absent or insufficient, based on vasodilation and activation of a neurotransmitter and immune function as medical efficacy of nitric oxide.

The disclosure provides a method for biohydrogen production. The method includes: mixing a hydrogen production medium and a buffer solution Na.sub.2HPO.sub.4/NaH.sub.2PO.sub.4 having a pH value of 5-9, to yield a first mixture; adding corn stalk powder and cellulase to the first mixture and mixing, to yield a second mixture; adding a suspension of photosynthesis bacteria HAU-M1 at the late exponential phase to the second mixture, to yield a third mixture; and sealing the third mixture and allowing for photo-fermentation biohydrogen production under anaerobic fermentation conditions.

The invention is directed to kits, compositions, tools and methods comprising a cyclic industrial process to form biocement. In particular, the invention is directed to materials and methods for decomposing calcium carbonate into calcium oxide and carbon dioxide at an elevated temperature, reacting calcium oxide with ammonium chloride to form calcium chloride, water, and ammonia gas; and reacting ammonia gas and carbon dioxide at high pressure to form urea and water, which are then utilized to form biocement. This cyclic process can be achieved by combining industrial processes with the resulting product as biocement. The process may involve retention of calcium carbonate currently utilized in the manufacture of Portland Cement.
