Biohythane production from marine macroalgae Sargassum sp. coupling dark fermentation and anaerobic digestion

Boosting dark fermentation with co-cultures of extreme thermophiles for biohythane production from garden waste.

Proof of principle of biohythane and potential energy production from garden waste (GW) is demonstrated in this study in a two-step process coupling dark fermentation and anaerobic digestion. The synergistic effect of using co-cultures of extreme thermophiles to intensify biohydrogen dark fermentation is demonstrated using xylose, cellobiose and GW. Co-culture of Caldicellulosiruptor saccharoly...

Two-phase thermophilic anaerobic digestion process for biohythane production treating biowaste: preliminary results.

This paper deals with the optimization of a two-phase anaerobic process treating biowaste for hydrogen and methane production. Neither physical nor chemical pre-treatments were used to optimize the process. The work was carried out at pilot scale, using two CSTRs (200 and 380 L working volume respectively) both maintained at thermophilic temperature (55 C) and fed semi-continuously with biowast...

Biogas production from food-processing industrial wastes by anaerobic digestion Biogas production from food-processing industrial wastes by anaerobic digestion

Industrial symbiosis: corn ethanol fermentation, hydrothermal carbonization, and anaerobic digestion.

The production of dry-grind corn ethanol results in the generation of intermediate products, thin and whole stillage, which require energy-intensive downstream processing for conversion into commercial animal feed products. Hydrothermal carbonization of thin and whole stillage coupled with anaerobic digestion was investigated as alternative processing methods that could benefit the industry. By...

Antifouling Compounds from Marine Macroalgae

Marine macroalgae produce a wide variety of biologically-active metabolites that have been developed into commercial products, such as antibiotics, immunosuppressive, anti-inflammatory, cytotoxic agents, and cosmetic products. Many marine algae remain clean over longer periods of time, suggesting their strong antifouling potential. Isolation of biogenic compounds and the determination of their ...
