The present work investigates a two-stage process scheme for cheese whey valorization through energy recovery in different forms by means of bio-electrochemical systems. first stage consisted an integrated H2 and electricity production. This combined dark fermentation with electrochemical system the aim overcoming typical thermodynamic/biochemical limitations enhancing recovery. second treatmen...

To investigate the changes of main ingredients in black garlic (BG) during fermentation, contents moisture, total acids and reducing sugars were determined. Allicin, 5-Hydroxymethylfurfural (5-HMF), phenols also determined as bioactive substances. DPPH scavenging capacity was to indicate antioxidant activity BG. The hardness color detected well. results showed that moisture content decreased fr...

BACKGROUND Molecular hydrogen, given its pollution-free combustion, has great potential to replace fossil fuels in future transportation and energy production. However, current industrial hydrogen production processes, such as steam reforming of methane, contribute significantly to the greenhouse effect. Therefore alternative methods, in particular the use of fermentative microorganisms, have a...

Huperzine A (HupA) is a plant alkaloid that is of great interest as a therapeutic candidate for the treatment of Alzheimer's disease. However, the current production of HupA from plants in large quantity is unsustainable because the plant resource is scarce and the content of HupA in plants is extremely low. Surprisingly, this compound was recently found to be produced by various endophytic fun...

Anaerobic digestion is a complex process involving hydrolysis, acidogenesis, acetogenesis and methanogenesis. The separation of the hydrogen-yielding (dark fermentation) and methane-yielding steps under controlled conditions permits the production of hydrogen and methane from biomass. The characterization of microbial communities developed in bioreactors is crucial for the understanding and opt...

The Sustainable Value methodology was used to compare and rank eight combinations of waste biomass types conversion technologies on a common assessment basis produce energy, energy vectors advanced biofuels. studied included agricultural agro-industrial residues, slurries effluents, pulp paper mill sludge, piggery effluents organic fractions municipal solid waste, biodiesel by (trans)esterifica...

BACKGROUND Biohydrogen production through dark fermentation using organic waste as a substrate has gained increasing attention in recent years, mostly because of the economic advantages of coupling renewable, clean energy production with biological waste treatment. An ideal approach is the use of selected microbial inocula that are able to degrade complex organic substrates with simultaneous bi...

The aim of this work was to assess the performances wine byproduct biomass for hydrogen production by dark fermentation. Grape must deposits from two grape varieties (Pinot Gris and Chardonnay) were considered, either with external microbial inoculum or without. We show that residues contain endogenous microflora, well adapted their environment, which can degrade sugars (initially contained in ...
