Endophytic bacteria improve root traits, biomass and yield of Helianthus tuberosus L. under normal and deficit water conditions.
Abstract
Drought is more concerned to be a huge problem for agriculture as it affects plant growth and yield. Endophytic bacteria act as plant growth promoting bacteria that have roles for improving plant growth under stress conditions. The properties of four strains of endophytic bacteria were determined under water deficit medium with 20% polyethylene glycol. Bacillus aquimaris strain 3.13 showed high 1-aminocyclopropane-1-carboxylate (ACC) deaminase production; Micrococcus luteus strain 4.43 produced indole acetic acid (IAA). Exopolysaccharide production was high in Bacillus methylotrophicus strain 5.18...

Porous carbon supported nanoceria derived from one step in situ pyrolysis of Jerusalem artichoke stalk for functionalization of solution-gated graphene transistors for real-time detection of lactic acid from cancer cell metabolism
Publication date: Available online 10 May 2019Source: Biosensors and BioelectronicsAuthor(s): Yulong Bi, Lihui Ye, Yu Mao, Lu Wang, Hao Qu, Jian Liu, Lei ZhengAbstractEffective detection of biomarkers for tumor cells has been the focus of attention. In this work, we have successfully fabricated a highly sensitive sensor based on solution-gated graphene transistors (SGGT) for detecting lactic acid content accumulated in tumor cells through their glycolysis metabolism. The sensing mechanism of the lactic acid sensor is attributed to electrochemical catalysis of H2O2 produced by the oxidation of lactic acid by lactate oxidase...

Repeated exposure to vegetable-enriched snack bars May increase Children's liking for the bars - But not for the vegetables.
In conclusion, repeated exposure may be a successful approach to increase liking for a vegetable bar, but does not generalize to changes in vegetable liking, and a lower exposure frequency may be advantageous.

Assessing the effect of pyrolysis temperature on the molecular properties and copper sorption capacity of a halophyte biochar.
Abstract
The capacity of biochar to take up heavy metals from contaminated soil and water is influenced by the pyrolysis temperature. We have prepared three biochar samples from Jerusalem artichoke stalks (JAS) by pyrolysis at 300, 500 and 700 °C, denoted as JAS300, JAS500, and JAS700, respectively. A variety of synchrotron-based techniques were used to assess the effect of pyrolysis temperature on the molecular properties and copper (Cu) sorption capacity of the samples. The content of oxygen-containing functional groups in the biochar samples decreased, while that of aromatic structures and alkaline m...

Molecules, Vol. 24, Pages 1674: Optimization of Spray-Drying Process of Jerusalem artichoke Extract for Inulin Production
sco J. Barba
Jerusalem artichoke is an important natural matrix for inulin production. In this experiment, response surface methodology (RSM) was employed to optimize the spray-drying parameters in order to determine the maximal inulin yield. For this study, three independent variables (heating temperature (Tª, 110–120 °C), creep speed (V, 18–22 rpm) and pressure (P, 0.02–0.04 MPa)) were used in the experimental design. Using the Box–Behnken design, the optimal parameters obtained were: drying temperature 114.6 °C, creep speed ...

Biomarkers of tuber intake
AbstractTubers are important crops as well as staple foods in human nutrition. Among tubers, the potato in particular has been investigated for its health effects. However, except for its contribution to energy and effects related to resistant starch, the role of potatoes and other tubers in human health is still debated. In order to establish firm evidence for the health effects of dietary tubers and processed tuber products, it is essential to assess total intake accurately. The dietary assessment in most studies relies mainly on self-reporting and may give imprecise quantitative information on dietary intakes. Biomarker...

Topinambur - new possibilities for use in a supplementation diet.
Abstract
Jerusalem artichoke (<i>Helianthus tuberosus Linne</i>) is a tuberous perennial plant of the Asteraceae family, which originates from North America, and is also known as wild sunflower or topinambur (TPB). It is characterized by good tolerance to frost, drought and poor soil, strong resistance to pests and plant diseases. For ages it was cultivated due to being both an edible tuber and having healing properties. In folk medicine, TPB leaves are used for the treatment of bone fractures and pain. TPB tubers are rich in sugar and have therefore been used for the production of functional f...

Molecules, Vol. 24, Pages 1068: Antitrypanosomal Activity of Sesquiterpene Lactones from Helianthus tuberosus L. Including a New Furanoheliangolide with an Unusual Structure
r
Schmidt
As part of our efforts to exploit the antitrypanosomal potential of sesquiterpene lactones (STL) from Helianthus tuberosus L. (Asteraceae), besides the known 4,15-iso-atriplicolide tiglate, -methacrylate and -isobutyrate, a hitherto unknown STL was isolated. Its structure was solved by extensive NMR measurements and confirmed by single crystal X-ray crystallography. This novel compound is a structural analog 4,15-iso-atriplicolide tiglate that possesses the same basic furanoheliangolide skeleton but differs in the position of the oxo function which is at C-2 instead of C-1, as well as in the fact that the ...
