“…The phenomenon might be mainly due to the selective enrichment of specific species capable of utilizing refractory sugars in stover hydrolyzate. In addition, it has been convinced that toxic byproducts in corn stover hydrolyzate can cause negative efforts on many species in seed sludges [27,44].

Temperature Seed sludgeCorn stover hydrolyzate Denaturing gradient gel electropho- resis (DGGE)Microbial diversity analysis a b s t r a c tThe temperature effect on fermentative hydrogen (H 2 ) production from corn stover hydrolyzate was investigated under mesophilic (37 and 30 C), thermophilic (55 C), and extreme thermophilic (70 C) conditions by using two typical seed sludges (activated sludge and anaerobic granular sludge). Among various temperatures, the fermentation at 55 C reached the optimal H 2 production with the values of 6.08 mmol-H 2 /g-utilized sugar for activated sludge and 7.74 mmol-H 2 /g-utilized sugar for anaerobic granular sludge, respectively. For the two seed sludges, the effectiveness of fermentation temperature on H 2 production both followed the order as 55 C > 70 C > 37 C z 30 C. The soluble metabolites composition at 55 C showed the highest acetate and butyrate concentrations, as well as the minimum ethanol production, coinciding with better H 2 -producing performances in these cases. Microbial community analysis indicated that microbial community diversity significantly decreased with increased fermentation temperature. Facultative anaerobes, such as Enterobacter spp., Klebsiella spp., and Citrobacter spp., were dominant in microbial community of the two seed sludges. As efficient H 2 producers, Bacillus sp. AB5283 in activated sludge and Thermoanaerobacterium sp. PO-2009 in anaerobic granular sludge might be mainly responsible for high H 2 yields under thermophilic condition.

“…Today, fossil fuels make up 80% of the primary energy consumed in the world (Escober et al 2009). The burning of fossil fuels causes much environmental damage and adds to global warming (Nigam -Singh 2010, Monlau et al 2014. In this respect, the development and application of alternative and renewable energy sources -especially the second-generation resources, mainly lignocellulosic biomass -has become a global focus today.…”

“…The anaerobic digestion process comprises four steps: hydrolysis, acidogenesis, acetogenesis, and methanogenesis. During this process, the lignocellulosic biomass is transformed into biogas (Monlau et al 2014); this has several benefits when compared the biogas produced from other forms of waste materials. A lesser amount of biomass sludge and the minimal odour emission are two main advantages (Smeth et al 1999) as well as its compliance with many waste strategies (Ward et al 2008).…”

-Fossil fuel depletion has led to an increasing number of research studies and applications focusing on renewable energy, such as different types of biomass. Lignocellulosic biomass represents an abundant source of biomass suitable for energy production in various forms. The present research investigates the application possibility of pedunculate oak bark (Quercus petrea (Matt.) Liebl.) for the production of biogas via anaerobic digestion. This research has significant novelty, as only a few examples on the utilization of tree bark wastes for the production of biogas can be found in the scientific literature. One of the key factors of increasing biogas yield is the efficient hydrolysis of the basic material, which is achieved by different pretreatment methods. In this study, oak bark was pretreated by microwave energy, by extraction, and by the combination of these two methods. The semi-continuous thermophylic anaerobic digestion of untreated oak bark resulted a 76.3 ml/g volatile solid specific methane yield over a 50-day period, which was not significantly lower than methane yield gained from pretreated basic material. Results indicated that oak bark is suitable for the production of biogas even without the application of the investigated pretreatment techniques. As extraction of oak bark does not impair biogas production, the complex biorefinery utilization of oak bark in the form of extraction bark polyphenols and the subsequent anaerobic fermentation of lignocellulosic residue can be accomplished in the future. lignocelluloses / biorefinery / forestry by-products / renewable energiesKivonat -A kocsánytalan tölgy (Quercus petreae (Matt.) Liebl.) kéreg alkalmazhatósága anaerob úton előállítható biogáz termelés céljára. A fosszilis energiahordozók kimerülése miatt számos alkalmazási terület és kutatás összpontosít a megújuló energiaforrásokra. A lignocellulózok, mint biomassza alapú energiahordozók kutatása releváns téma, mivel nagy mennyiségben állnak rendelkezésre. Ezen kutatás a kocsánytalan tölgy (Quercus petreae (Matt.) Liebl.) kéreg alkalmazási lehetőségeit vizsgálja az anaerob úton előállítható biogáz termelés céljára. A kéreg hulladék effajta felhasználásával foglalkozó szakirodalmak száma szegényes. A lignocellulózok esetében kulcs fontosságú eljárás az alapanyag hidrolízise a biogázhozam, ezzel együtt a metánhozam növelése érdekében. A tölgy kéreg alapanyag előkezelése mikrohullámmal, extrakcióval és együttes alkalmazásukkal történt. A kezeletlen tölgy kéreg 50 napos, félfolyamatos, termofil anaerob fermentáció során 76.3 ml/g szerves szárazanyag fajlagos metánhozam érhető el, ami szignifikánsan nem alacsonyabb a kezelthez képest. Az eredmények alapján a tölgy kéreg, alkalmas metán előállításra előkezelési eljárások nélkül is. Mivel a kéreg extrakciója nem rontja a biogáz termelés hatékonyságát, ezért a kéreg melléktermék komplex kémiai hasznosítása, az extrakt anyagok kivonása valamint a visszamaradt lignocellulóz vázanyag anaerob fermentációja által a jövőben lehetséges. lignocellulózok / ...

“…The hot gaseous products are difficult to capture using a conventional gas collecting device during the sudden release of high pressure after SE pretreatment. There have been several studies published concerning the effects of lignocellulosederived inhibitors on enzymatic hydrolysis (Monlau et al 2014;Jonsson and Martin 2016). However, very few of these studies specifically have analyzed the inhibitors in gaseous products from SE pretreatment of corn stalk and their inhibitory effects on enzymatic hydrolysis.…”

In order to reduce production costs, heated explosion gases generated from dilute-sulfuric acid catalytic steam explosion (SE) pretreatment in the pilot production were recovered to provide energy for subsequent steps and to supply heated water (gas condensate water) for the washing steps. However, organic compounds in the explosion gases accumulated in the circulating water during continuous production, which affected subsequent enzymatic hydrolysis steps. The aim of this work was to investigate the major organic components in SE pretreatment gaseous products, their formation mechanism, and their inhibitory effects on the subsequent enzymatic hydrolysis of pretreated corn stalk.
