“…In our earlier studies (Gnanambal et al, 2014), the lignocellulosic biomass was fermented using Pleurotus florida by solid state fermentation and the biochemical constituents of the lignocellulosic biomass was determined. Lay et al, 2012, reported that the nutrient addition could enhance the total biogas production. The appropriate balance of nutrients is very important for the anaerobic digestion of rice straw.…”

Effect of raw and biologically treated lignocellulosic biomass using cow dung slurry for biogas production is reported. Biomass is an energy source. Water containing biomass such as sewage sludge, cow dung slurry and lignocellulosic waste, has several important advantages and one of the key feature is renewability. Cow dung slurry has the potential to produce large amounts of biogas. Four categories of bacteria viz., hydrolytic, fermentative, fermentative acidogenic and acidogenic-methanogenic bacteria are involved in the production of biogas. The different characteristics of the cow dung slurry were determined according to standard methods. Hemicellulose, cellulose and lignin content of the lignocellulosic waste were also determined in our earlier studies. The substrates were digested under anaerobic condition for 5 days. The total biogas and methane produced during anaerobic digestion were estimated on 5 th day. The total biogas produced during digestion was estimated by water displacement method. Biological methane production was estimated by using Saccharometer.

“…This results was opposite while MCW was cultivated at liquid state fermentation. 1 Larger particle size 0.59-1.19 mm resulted in peak HY of 0.29 mmol H 2 /g TVS whilst high organic matter and TOC removal efficiencies were 11.4% (from 91.6% to 81.2%) and 11.3% (from 45.5% to 40.6%) respectively ( Figure 2). However, peak HPR max and SHPR max was obtained at particle size < 0.074 mm.…”

“…Bioenergy from the biomass crops like sweet sorghum, potatoes, sugarcane, soybean and palm oil have been used as raw materials. 1 Mushroom cultivation waste (MCW) is available abundantly and easy to collect thus it has attained considerable attention to be used as feedstock for the biohydrogen process. MCW is a polypropylene bag stuffed with wood flour and nutrients for growing mushroom and is a lignocellulosic material containing cellulose, hemicellulose, and lignin.…”

Mushroom cultivation waste (MCW) is a polypropylene bag stuffed with wood flour and nutrients for growing mushroom, which is a feasible feedstock for anaerobic biohydrogen production owing to its abundant availability, high organic and nutrient content. This study optimized the seed inoculum from various waste sludges (sewage sludge, cow dung and pig slurry), nutrient addition and operation conditions (moisture content and MCW powder particle size) for maximal biohydrogen production by solid-state fermentation (SSF). SSF batch test was operated at a MCW 3 g total volatile solid (TVS)/L, temperature 55°Cand rotation speed of 15 rpm with a vertical rotative shaker. The peak hydrogen production performance of hydrogen production rate (HPR) 9.50 mol H 2 /kg-d and hydrogen yield (HY) 0.29 mmol H 2 /g TVS) are obtained using sewage sludge 2 seed inoculum, nutrients addition, moisture content 70% and particle size of 1.190~0.590 mm. The results show that the MCW has the potential for hydrogen production by anaerobic mixed microflora using solid-state fermentation. The bioenergy of 1842 kWh while using SSF to conver MCW to produce biohydrogen and it could reduce CO 2 emission of 114-178 kg per year comparing using fossil fuel such as coal, fuel oil and natural gas.

“…Dark fermentation of organic materials by bacteria presents a promising route of bio-hydrogen production, due to its environmental friendliness and high production [4, 5]. Low value feedstock and high capacity microorganisms are the two prime principles to reduce the cost of bio-hydrogen production [6]. Lignocellulosic feedstock is the most abundant and cheap resource in nature.…”

BackgroundEnergy shortage and environmental pollution are two severe global problems, and biological hydrogen production from lignocellulose shows great potential as a promising alternative biofuel to replace the fossil fuels. Currently, most studies on hydrogen production from lignocellulose concentrate on cellulolytic microbe, pretreatment method, process optimization and development of new raw materials. Due to no effective approaches to relieve the inhibiting effect of inhibitors, the acid pretreated lignocellulose hydrolysate was directly discarded and caused environmental problems, suggesting that isolation of inhibitor-tolerant strains may facilitate the utilization of acid pretreated lignocellulose hydrolysate.ResultsThermophilic bacteria for producing hydrogen from various kinds of sugars were screened, and the new strain named MJ1 was isolated from paper sludge, with 99% identity to Thermoanaerobacterium thermosaccharolyticum by 16S rRNA gene analysis. The hydrogen yields of 11.18, 4.25 and 2.15 mol-H2/mol sugar can be reached at an initial concentration of 5 g/L cellobiose, glucose and xylose, respectively. The main metabolites were acetate and butyrate. More important, MJ1 had an excellent tolerance to inhibitors of dilute-acid (1%, g/v) pretreated sugarcane bagasse hydrolysate (DAPSBH) and could efficiently utilize DAPSBH for hydrogen production without detoxication, with a production higher than that of pure sugars. The hydrogen could be quickly produced with the maximum hydrogen production reached at 24 h. The hydrogen production reached 39.64, 105.42, 111.75 and 110.44 mM at 20, 40, 60 and 80% of DAPSBH, respectively. Supplementation of CaCO3 enhanced the hydrogen production by 21.32% versus the control.ConclusionsThese results demonstrate that MJ1 could directly utilize DAPSBH for biohydrogen production without detoxication and can serve as an excellent candidate for industrialization of hydrogen production from DAPSBH. The results also suggest that isolating unique strains from a particular environment offers an ideal way to conquer the related problems.Electronic supplementary materialThe online version of this article (doi:10.1186/s12934-017-0692-y) contains supplementary material, which is available to authorized users.
