Biohydrogen (H2) production via dark fermentation (DF) is a promising renewable energy technology. In the process, the enrichment of microbial communities producing hydrogen is very important as their activities considerably affect the overall performance.
2018/2/1/ · In their initial work, they soaked the waste textile with NaOH/urea (12/7 v/ w %) at À20 C for 6 hours and observed more than a 9.5% enhancement in cellulase activity versus the untreated sample .
2021/1/1/ · Dark fermentation is a technically feasible technology for achieving carbon dioxide-free hydrogen production. This review presents the current findings on continuous hydrogen production using dark fermentation. Several operational strategies and reactor configurations have been suggested. The formation of attached mixed-culture
2011/6/15/ · The beer brewing process often generates large amounts of wastewater effluent and solid wastes that must be disposed off or treated in the least costly and safest
2023/11/15/ · Most fermentation waste filtrates can be used as raw materials for producing bio-fertilizers to reduce wastewater emissions and environmental pollution, but their bio-fertilizer utilization depends on the nutrients contained and their metabolized by functional microorganism. To achieve bio-fertilize
2018/11/3/ · An estimated 72% of biofuel production (in energy terms) was fuel ethanol, 23% was biodiesel, and 4% was hydrotreated vegetable oil (REN21 2017 ). More than 80% of the world’s biodiesel production is from vegetable oils, with the majority produced from European canola and soybeans from the United States, Brazil, and Argentina.
2016/1/1/ · Abstract. Food waste (FW) has been a major concern worldwide due to its large amount of production and improper disposal .

Kurhade and Dalai (2018) studied 12-tungstophosphoric acid (TPA) (H 3 PW 12 O 40 .nH 2 O) impregnated on the γ-Al 2 O 3 catalyst for the biodiesel production. An optimized conversion of 94.9 ± 2.3% can be achieved with 10 wt.% of the catalyst loading, 17.5:1 M methanol/oil ratio, 200°C, and 4 MPa in 10 h.
2023/7/3/ · Starch is a readily available and abundant source of biological raw materials and is widely used in the food, medical, and textile industries. However, native starch with insufficient functionality limits its utilization in the above applications; therefore, it is modified through various physical, chemical, enzymatic, genetic and multiple modifications. This
2022/3/24/ · Research on solid-state fermentation has increased exponentially between 1970 and 2020 as a result of increasing prospects of using solid-state fermentation to
2018/3/10/ · As with PLAFRACTOR, all the fermentation operations could possibly be carried out, aseptically, in a single unit. The horizontal expansion of the bioreactor (100–400 cm or 150–300 cm) was greater than the vertical height (1 m, 2 or 2.5 m) and was estimated to replace 50–100, 2 kg plastic SSF bags.
