“…Methanogens were inhibited with 20 mM BESA and 250 mL medium was added to the flasks. One liter of medium contained 10.7 g NaH 2 PO 4 , 3.2 g Na 2 HPO 4 , 0.6 g NH 4 O, 0.5 g EDTA, 2 g yeast extract, 0.013 g Na 2 S 2 O 4 and vitamin solution (DSMZ medium No141, German Collection of Microorganisms and Cell Cultures). The biogas and liquid samples were collected two or three times a week and the pH was adjusted (7.0 AE 0.1) at the same time.…”

“…Hydrogen gas has many advantages; it has most energy per unit mass (122 MJ/kg), and it can be used for electricity production in fuel cells with water and heat as the only endproducts [1,2]. Dark fermentative hydrogen productions from both pure cellulosic materials, such as cellulose and xylan [3,4], and renewable cellulosic materials, such as food waste, sugarcane bagasse and paper mill waste [4e6], have been studied extensively. Grass silage is a potential cellulosic material for biological hydrogen production.…”

“…Agricultural residues as a source of lignocellulosic waste materials are extensively used in bio-hydrogen production studies. Rice straw, wheat straw, sugar cane bagasse, beer lees, jackfruit peel and food waste are some of waste materials that are recently used in some research works for bio-hydrogen production [2,13,[16][17][18][19][20][21] . Lignocellulosic materials have complex structure made from cellulose, hemicellulose, and lignin and consist of 50 to 80% carbohydrates in dry weight [22].…”

Abstract:In this study, batch biohydrogen production by co-digestion of raw rice straw and activated sewage sludge was investigated with different inoculum heat treatment, pH, S/X ratio (based on VS) and substrate sizes under mesophilic condition. In order to achieve a high bio-hydrogen yield and methanogens activity inhibition, heat treatment of inoculum was optimized at different exposure times (30, 45 & 60 min) and temperature ranges (80, 90 and 100 °C) prior to dark fermentation process. Collected data was analysed using response surface methodology (RSM).The heat treatment of inoculum at 100 °C for 60 minutes produced the highest bio-hydrogen yield of 14.22 NmL H2/g VS at concentration of 70.97 % and Production of 0.073 NmLCH4/gVS at 0.17% concentration in total produced biogas. The raw rice straw was also co-digested with heat-treated inoculum at different ratios of volatile solids (2:1, 4:1 and 6:1) and initial pH (4, 4.75 and 5.5) as numerical variables and 4 categories of substrate size ( (250-500 µm], (500 µm-2mm], (2-20mm), [20-30mm]) . The highest bio-hydrogen yield of 14.70 NmL/g VS was recognized at the optimum initial pH of 5.01 and S/X ratio of 4.54:1 using 2-20 mm rice straw.

“…Maximum MP of 3,547 mL CH4/L was obtained from the solid residues of a co-digestion of silage with cow dung pretreated by an alkali plus enzyme treatment. Moreover, alkali pretreatment can break the lignin barrier and disrupt the crystallinity of cellulose, thus increased the susceptibility of cellulose to enzyme [41,46,47].…”

Methane production from co-digestion of grass with cow dung and silage with cow dung was conducted by a bioaugmentation technique. For self-fermentation, maximum methane yield (MY) of 176.66 and 184.94 mL CH4/g-VSadded were achieved at a ratio of grass to cow dung and silage to cow dung of 1:1, respectively. A higher maximum MY of 179.59 and 208.11 mL CH4/g-VSadded was obtained from co-digestion of grass with cow dung and silage with cow dung bioaugmented with anaerobic sludge at a ratio of 3:1. The solid residue left over after co-digestion at a ratio of 3:1 was pretreated by alkaline plus enzyme before used to produce methane and a maximum MY of 333.63 and 301.38 mL CH4/g-VSadded, respectively, was achieved. Overall power generated from codigestion of grass with cow dung plus pretreated solid residues and co-digestion of silage with cow dung plus pretreated solid residues were 0.0397 and 0.007 watt, respectively.
