Hydrolysis kinetics of inulin by imidazole-based acidic ionic liquid in aqueous media and bioethanol fermentation
This article focused on the inulin-containing energy biomass, Jerusalem artichoke, to explore environment-friendly processes for bioethanol production. An imidazole-based acidic ionic liquid (VImaILs) was prepared as the catalyst of inulin hydrolysis in aqueous media. The hydrolysis kinetics was studied under different conditions. The kinetic parameters of hydrolysis by VImaILs and dilute sulfuric acid were estimated and compared. This work demonstrated that the hydrolysis rate of inulin into reducing sugars by VImaILs was obviously faster than that by the latter. The proposed kinetic model successfully predicted the inuli...

Carbonell-Barrachina, Joanna Miedzianka, Joanna Kolniak-Ostek, Agnieszka Tajner-Czopek, Elżbieta Rytel, Adam Siwek, Dorota Miarka, Wioletta Drożdż The development of functional corn snacks by adding nutritional rich additives is an interesting strategy to promote the consumption of antioxidant rich ingredients, such as polyphenols. Flours made from Jerusalem artichoke tubers, amaranth seeds, and pumpkin flesh were added at level of 10% to corn grits in twin-screw ext...

Development of heterogeneous preparation with inulinase for tubular reactor systems
Publication date: Available online 31 March 2016 Source:Journal of Molecular Catalysis B: Enzymatic Author(s): M.G. Holyavka, M.P. Evstigneev, V.G. Artyukhov, V.V. Savin We developed highly stable heterogeneous preparations of inulinase immobilized on the ion-exchange matrixes and show that such preparations effectively split the chemically pure inulin and the inulin contained in plant extracts. The optimal conditions of hydrolysis are created for the migration of inulin solution from top to bottom (the downsteam flow) through the column filled by immobilized compounds extracted from Kluyveromyces marxianus and...

Synergistic effect between the recombinant exo-inulinase and endo-inulinase on inulin hydrolysis
Publication date: Available online 17 March 2016 Source:Journal of Molecular Catalysis B: Enzymatic Author(s): Yuan Liu, Shun-Hua Zhou, Cheng-Yu Rong, Zhe Chi, Zhen-Ming Chi, Guang Lei Liu An exo-inulinase gene from Kluyveromyces marxianus and an endo-inulinase gene from Aspergillus niger were cloned and expressed in Yarrowia lipolytica, respectively. Then, the purified recombinant exo-inulinase (rEXINU) and endo-inulinase (rENINU), either individual or combination with another, were used for hydrolysis of inulin and inulin in tuber meal of Jerusalem artichoke. After the analysis of the dynamic hydrolysis p...

Hydrolysed inulin alleviates the azoxymethane-induced preneoplastic aberrant crypt foci by altering selected intestinal microbiota in Sprague-Dawley rats.
This study determines the effect of hydrolysed inulin with different degrees of polymerisation on alteration of intestinal microbiota and their activities on azoxymethane (AOM)-induced preneoplastic aberrant crypt foci (ACF) in rats. Materials and methods Seventy-two male Sprague-Dawley rats were randomly divided into six groups (three control and three AOM-treated groups) and the animal were fed with either a normal diet or diet containing 10% of long-chain inulin (InuL) or short-chain inulin (InuS), respectively, for 17 weeks. Colon cancer was induced in rats by injecting AOM subcutaneously at the 8th and 9th week of the...

The biotransformation of brewer’s spent grain into biogas by anaerobic microbial communities
In this study, we will show an effective conversion of BSG into biogas by selected microbial communities, obtained from different sources (animal manure and previously isolated microbial consortia). The stimulation of methanogenesis was reached by the co-digestion of JA’s phytomass (stem and leaves). The optimized conditions for microbial stable cultivation included the use of nutrient medium, containing yeast extract and trace element solution. The optimal BSG concentration in biogas production was 50 and 100 g L−1. Under thermophilic conditions, the maximum total methane production reached 64 %, and it comprised a...

Catalytic conversion of Jerusalem artichoke tuber into hexitols using the bifunctional catalyst Ru/(AC-SO3H)
Publication date: October 2015 Source:Chinese Journal of Catalysis, Volume 36, Issue 10 Author(s): Likun Zhou, Zhenlei Li, Jifeng Pang, Mingyuan Zheng, Aiqin Wang, Tao Zhang Jerusalem artichoke tuber (JAT) was employed as a feedstock for production of hexitols under mild conditions over a sulfonated activated carbon supported Ru catalyst (Ru/(AC-SO3H)). In comparison with conventional Ru/AC catalyst, the sulfonation process of the carbon support was observed to create abundant surface acid groups, which in turn function as the anchoring sites for Ru nanoparticles, thus increasing the dispersion of Ru. Conse...

Impact of zinc supplementation on the improved fructose/xylose utilization and butanol production during acetone–butanol–ethanol fermentation
Publication date: Available online 3 July 2015 Source:Journal of Bioscience and Bioengineering Author(s): You-Duo Wu , Chuang Xue , Li-Jie Chen , Feng-Wu Bai Lignocellulosic biomass and dedicated energy crops such as Jerusalem artichoke are promising alternatives for biobutanol production by solventogenic clostridia. However, fermentable sugars such as fructose or xylose released from the hydrolysis of these feedstocks were subjected to the incomplete utilization by the strains, leading to relatively low butanol production and productivity. When 0.001 g/L ZnSO4·7H2O was supplemented into the medium containing fru...

Ethanol production from Jerusalem artichoke tubers at high temperature by newly isolated thermotolerant inulin-utilizing yeast Kluyveromyces marxianus using consolidated bioprocessing.
Abstract
Thermotolerant inulin-utilizing yeast strains were successfully isolated in this study. Among the isolated strains, Kluyveromyces marxianus DBKKU Y-102 was found to be the most effective strain for direct ethanol fermentation at high temperature from fresh Jerusalem artichoke (JA) tubers without inulin hydrolysis under consolidated bioprocessing (CBP). The maximum ethanol concentrations produced by this strain under the optimum culture conditions were 104.83 and 97.46 g L(-1) at 37 and 40 °C, respectively. Data from this study clearly demonstrated that the use of thermotolerant inulin-utilizin...
