Use of Jerusalem artichoke aerial parts as forage in fat-tailed sheep diet
This study was conducted to evaluate the effects of using different dietary levels of aerial parts of Jerusalem artichoke (Helianthus tuberosus) (JAAP) on voluntary feed intake, digestibility, microbial nitrogen (N) synthesis (MNS), and N retention in Iranian fat-tailed sheep. Twenty Chall rams averaging 15-18 months of age, and with an initial live body weight of 66.7 ± 7.01 (SD) kg, were randomly assigned to five dietary treatments (4 sheep/treatment) in which alfalfa hay was replaced with different levels (0, 25, 50, 75, or 100%, respectively) of JAAP. The animals were housed in individual metabolism boxes for a pe...

Molecules, Vol. 24, Pages 559: Effects of Pulsed Electric Field Treatment on Compression Properties and Solutes Diffusion Behaviors of Jerusalem artichoke
orobiev
Jerusalem artichoke is widely used as raw material for industrial production of inulin. Pressing (compression) and diffusion are two effective technologies for bio-compounds’ recovery from plants. In this work, pulsed electric field (PEF) treatment at 400, 600, and 800 V/cm during 100 ms was applied to facilitate juice and solutes recovery from Jerusalem artichoke. The application of PEF led to electroporation of cell membranes and enhanced the tissue compression/juice expression and solutes diffusion. The consolidation coefficient (calculated by application of semi-empirical model) of PEF treated...

Efficacy of synbiotic Jerusalem artichoke and Lactobacillus rhamnosus GG-supplemented diets on growth performance, serum biochemical parameters, intestinal morphology, immune parameters and protection against Aeromonas veronii in juvenile red tilapia (Oreochromis spp.)
In this study, the effect of supplementing the diet of red tilapia (Oreochromis spp.) with Jerusalem artichoke (Helianthus tuberosus) and Lactobacillus rhamnosus GG (LGG) was evaluated. Growth performance, serum biochemical parameters, intestinal morphology, goblet cell counts, immune parameters and protection against Aeromonas veronii challenge were determined. The results showed that fish fed with synbiotic-supplemented diets had a significantly higher (P < 0.05) feed conversion ratio (FCR), specific growth rate (SGR), and average daily gain (ADG) than fish fed with a control diet. The synbiotic-supplemented diet...

Engineering Trichoderma reesei Rut-C30 with the overexpression of egl1 at the ace1 locus to relieve repression on cellulase production and to adjust the ratio of cellulolytic enzymes for more efficient hydrolysis of lignocellulosic biomass
In this study, T. reesei QS305 with high endoglucanase activity was developed from T. reesei Rut-C30 by replacing the transcription repressor gene ace1 with the coding region of endoglucanase gene egl1. Compared to T. reesei Rut-C30, T. reesei QS305 showed 90.0% and 132.7% increase in the activities of total cellulases and endoglucanases under flask culture conditions. When cellulase production by T. reesei QS305 was performed in the 5-L fermentor, a cellulases activity of 10.7 FPU/mL was achieved at 108 h, 75.4% higher than that produced by T. reesei Rut-C30. Moreover, cellulases produced by T. reesei QS305 were more effi...

Genes, Vol. 9, Pages 422: Neo-Domestication of an Interspecific Tetraploid Helianthus annuus × Helianthus tuberous Population That Segregates for Perennial Habit
Loren H. Rieseberg
Perennial agriculture has been proposed as an option to improve the sustainability of cropping systems, by increasing the efficiency of resource use, while also providing ecosystem services. Neo-domestication, the contemporary domestication of plants that have not previously been used in agriculture, can be used to generate new crops for these systems. Here we explore the potential of a tetraploid (2n = 4x = 68) interspecific hybrid sunflower as a perennial oilseed for use in multifunctional agricultural systems. A population of this novel tetraploid was obtained from crosses between the annual dip...

Investigating the conditions for the effectiveness of nudging: Cue-to-action nudging increases familiar vegetable choice
Publication date: Available online 13 August 2018Source: Food Quality and PreferenceAuthor(s): V.J.V. Broers, S. Van de Broucke, C. Taverne, O. LuminetAbstractInulin-type fructans (ITF), which are fibres found in vegetables such as salsify, artichoke and Jerusalem artichoke, are known for their prebiotic capacities and may contribute to preventing obesity. The current study aimed to assess the differential effects of type-2 and combined type-1 and -2 nudges to increase the choice for “prebiotic” vegetables at a hot vegetable buffet of a university restaurant, using a nonrandomized intervention study design involving tw...

Fructooligosaccharides and appetite
Purpose of review
Dietary fiber may play a role in obesity prevention through reduction of body weight and control of appetite, however, not all fibers are created equally, and characteristics of fiber such as viscosity, fermentability and solubility may affect appetite differently.
Recent findings
Although early studies supported that fructan fibers, including inulin, fructooligosaccharides, and oligofructose affected satiety, more recent studies are less supportive. We found that a higher dose of fiber such as oligofructose (16 g/day) is needed and for a longer duration (12–16 weeks) to detect differences in app...

The application of ohmic heating for inulin extraction from the wet-milled and dry-milled powders of Jerusalem artichoke (Helianthus tuberosus L.) tuber
In this study, ohmic heating was applied for inulin extraction from the Jerusalem artichoke tuber (JAT). Raw materials for extraction were prepared by two different schemes comprising milling the blanched JAT slices and water mixture (wet milling) and grinding the dried JAT to be powder before mixing water (dry milling). Also, the inulin extracts were evaporated using a rotary evaporator and then spray-dried to be inulin powder. The main objectives were (1) to investigate the effects of applying ohmic heating on the extraction yield and quality of inulin extracts in comparison with conventional method and (2) to determine ...

Pyrolysis Temperature-Dependent Changes in the Characteristics of Biochar-Borne Dissolved Organic Matter and Its Copper Binding Properties.
Abstract
The dissolved organic matter (DOM) samples from biochars produced from Jerusalem artichoke stalks by pyrolysis at 300, 500, and 700 °C were characterized using a combination of spectroscopic techniques. Additionally, the binding affinities (long KM) and the complexation capacities (CL) of the DOM samples with Cu(II) were calculated to assess their Cu binding properties. The biochar-borne DOM contained mainly humic-like components (C1-C3) with a small amount of a protein-like component (C4). As the charring temperature increased, the concentrations of released DOM decreased. The low temperature b...
