“…However, no LAB was detected in the mixed enzymes. The findings were consistent with our previous reports [60,61] that the anaerobic granules collected from the anaerobic digester at Khon Kaen Brewery Co., Ltd., Khon Kaen, Thailand contained Lactobacillus spp. The presence of LAB was considered adverse as, aside from their competitive consumption of substrate, lactic acid can lower the pH of a fermentation broth, leading to unfavorable conditions for hydrogen synthesis [62].…”

Simultaneous saccharification and fermentation (SSF) and pre-hydrolysis with SSF (PSSF) were used to produce hydrogen from the biomass of Chlorella sp. SSF was conducted using an enzyme mixture consisting of 80 filter paper unit (FPU) g-biomass−1 of cellulase, 92 U g-biomass−1 of amylase, and 120 U g-biomass−1 of glucoamylase at 35 °C for 108 h. This yielded 170 mL-H2 g-volatile-solids−1 (VS), with a productivity of 1.6 mL-H2 g-VS−1 h−1. Pre-hydrolyzing the biomass at 50 °C for 12 h resulted in the production of 1.8 g/L of reducing sugars, leading to a hydrogen yield (HY) of 172 mL-H2 g-VS−1. Using PSSF, the fermentation time was shortened by 36 h in which a productivity of 2.4 mL-H2 g-VS−1 h−1 was attained. To the best of our knowledge, the present study is the first report on the use of SSF and PSSF for hydrogen production from microalgal biomass, and the HY obtained in the study is by far the highest yield reported. Our results indicate that PSSF is a promising process for hydrogen production from microalgal biomass.

“…Consequently, more HP and HY were obtained (Table 1). In addition, C. butyricum is a well known hydrogen producer and has been reported to show the ability to utilize various kinds of substrates such as glucose [41], sugarcane syrup [41,42] and lignocellulosic biomass [43]. The concentration of soluble metabolite products (SMPs) in the fermentation broth with C. butyricum were higher than that without C. butyricum.…”

Abstract:The objective of this study was to efficiently utilize the napier grass and its silage to produce bio-hydrogen and methane by a two-stage process in batch mode. First, the production of hydrogen from a co-digestion of grass with cow dung and silage with cow dung by Clostridium butyricum Thailand Institute of Scientific and Technological Research (TISTR) 1032 was conducted. The results indicated that bio-hydrogen production by C. butyricum TISTR 1032 gave a higher hydrogen yield (HY) than without C. butyricum addition. The HY of 6.98 and 27.71 mL H 2 /g-Volatile solid added (VS added ), were obtained from a co-digestion of grass with cow dung and silage with cow dung by C. butyricum, respectively. The hydrogenic effluent and solid residue left over after hydrogen fermentation were further used as substrates for methane production (Batch I). Methane yield (MY) from hydrogenic effluent of grass with cow dung and silage with cow dung were 169.87 and 141.33 mL CH 4 /g-COD added (COD: chemical oxygen demand), respectively. The maximum MY of 210.10 and 177.79 mL CH 4 /g-VS added , respectively, were attained from solid residues left over after bio-hydrogen production pretreated by enzyme (cellulase cocktail) and alkali (NaOH). Afterward, solid residue left over after methane production (Batch I) was used as the substrate for methane production (Batch II). A maximum MY of 370.39 and 370.99 mL CH 4 /g-VS added were achieved from solid residue repeatedly pretreated by alkaline plus enzyme, respectively. The overall energy yield in the two-stage bio-hydrogen and methane production process was derived from a bio-hydrogen production, a methane production from hydrogenic effluent, methane production of pretreated solid residue (Batch I) and methane production of repeatedly pretreated solid residue (Batch II), which yielded 480.27 and 204.70 MJ/g-VS added , respectively.

“…Samples were centrifuged at 10,000 rpm for 5 min in order to precipitate the suspended microbes. The cell pellets were collected and kept in 50% sterile glycerol at −20 °C prior to microbial community analysis [7] by PCR-DGGE following the method of Kongjan et al (2011) [57]. Most of the bands were excised from the gel and re-amplified.…”

“…For example, Cater et al [4] reported a successful use of cocultures of Pseudobutyrivibrio xylanivorans Mz5 (T) and Fibrobacter succinogenes S85 and co-culture of Clostridium cellulovorans and Fibrobacter succinogenes S85 for methane production from brewery spent grain. In addition, the use of mixed cultures such as sewage sludge [5], anaerobic digested sludge [6], upflow anaerobic sludge blanket (UASB) granules [7] and activated sludge [8,9] were found to enhance biogas production. Based on this information, an addition of inocula or bioaugmentation technique is a promising approach to enhance the AD process.…”

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.
