Thermophilic co-fermentation of cassava stillage (CS) and cassava excess sludge (CES) were investigated for hydrogen and methane production. The highest hydrogen yield (37.1 ml/g-total-VS added) was obtained at VS(CS)/VS(CES) of 7:1, 17% higher than that with CS digestion alone. The CES recycle enhanced the substrate utilization and improved the buffer capacity. Further increase the CES fractio...

Cellulosic ethanol (CE) can not only be produced from a nonedible, cheap, and abundant lignocellulose feedstock but also reduce carbon footprint significantly compared to starch ethanol. Despite great stimulation worldwide, CE production has yet commercialized because of the complexity lignocellulose. Therefore, intensive research development are needed improve technologies. In this study, cost...

Corn dried distiller’s grain with solubles (cDDGS) is a feeding ingredient for monogastric animals but limited inclusion rate due to its imbalanced amino acids, high fiber content, and anti-nutritional compounds. Moreover, production of cDDGS costly energy intensive. This study investigated fungal fermentation corn stillage mixing other dry agro-industrial residues which could by-pass the energ...
