Amino Acid Improving and Physical Qualities of Extruded Corn Snacks Using Flours Made from Jerusalem Artichoke (Helianthus tuberosus), Amaranth (Amaranthus cruentus L.) and Pumpkin (Cucurbita maxima L.)
Abstract
The effectiveness of supplementation with 5, 10 and 15% of flours made from Jerusalem artichoke roots (JAF), amaranth seeds (AF) and pumpkin tissue (PF) on the physical properties of corn‐based snacks and the improvement of their amino acids (aa) composition was studied. No higher than 10% enrichment of corn grits particularly improved texture, porosity and specific density of snacks and revealed suitable expansion, a delicate crunchy texture. The lightness of the extrudates decreased after PF and JAF had been used. PF or JAF at the higher level (10 or 15%) increased the redness of snacks. AF affected the reduct...

Consolidated ethanol production from Jerusalem artichoke tubers at elevated temperature by Saccharomyces cerevisiae engineered with inulinase expression through cell surface display.
Abstract
Ethanol fermentation from Jerusalem artichoke tubers was performed at elevated temperatures by the consolidated bioprocessing strategy using Saccharomyces cerevisiae MK01 expressing inulinase through cell surface display. No significant difference was observed in yeast growth when temperature was controlled at 38 and 40 °C, respectively, but inulinase activity with yeast cells was substantially enhanced at 40 °C. As a result, enzymatic hydrolysis of inulin was facilitated and ethanol production was improved with 89.3 g/L ethanol produced within 72 h from 198.2 g/L total inulin sugars consu...

Research on the Solid State Fermentation of Jerusalem Artichoke Pomace for Producing R,R-2,3-Butanediol by Paenibacillus polymyxa ZJ-9.
In this study, the fermentation parameters of SSF were optimized and determined in flasks. A novel bioreactor was designed and assembled for the laboratory scale-up of SSF, with a maximum yield of R,R-2,3-BD (67.90 g/kg (JAP)). This result is a 36.3% improvement compared with the flasks. Based on the same bath of Jerusalem artichoke powder, the total output of R,R-2,3-BD increased by 38.8% for the SSF of JAP combined with the SMF of inulin extraction. Overall, the utilization of JAP for R,R-2,3-BD production was beneficial to the comprehensive utilization of Jerusalem artichoke tuber.

Plant growth promotion properties of bacterial strains isolated from the rhizosphere of the Jerusalem artichoke (Helianthus tuberosus L.) adapted to saline –alkaline soils and their effect on wheat growth
Canadian Journal of Microbiology, e-First Articles. The Jerusalem artichoke (JA; Helianthus tuberosus), known to be tolerant to saline –alkaline soil conditions, has been cultivated for many years in the Yellow River delta, Shandong Province coastal zone, in China. The aim of our study was to isolate nitrogen-fixing bacteria colonizing the rhizosphere of JA and to characterize other plant growth promotion properties. The ultimate goal was to identify isolates that could be used as inoculants benefiting an economic crop, in particular for improving wheat growth production in the Yellow River delta. Bacterial strains were ...

Spray drying of inulin component extracted from Jerusalem artichoke tuber powder using conventional and ohmic-ultrasonic heating for extraction process
In this study, various ohmic heating conditions and conventional heating were applied in the inulin extraction process from Jerusalem artichoke tuber (JAT) powder. The inulin extracts were evaporated to be around 30 °Brix and then spray-dried to be inulin powder. The main objectives were (1) to compare the quality of inulin extracts obtained from different extraction conditions and (2) to evaluate the yield of inulin powder production from JAT powder and the inulin powder quality. The results showed that the electrical conductivities of JAT powder solutions ranged between 0.0677 and 0.2057 S/m. The application of ohmic h...

Pseudoxanthomonas helianthi sp. nov., isolated from roots of Jerusalem artichoke (Helianthus tuberosus).
Abstract
A bacterium designated as strain roo10T was isolated from roots of Jerusalem artichoke (Helianthus tuberosus). Cells are Gram-stain-negative and non-flagellated rods. The phylogenetic analysis indicated that it was a member of the genus Pseudoxanthomonas, and its close relatives included Pseudoxanthomonas kalamensis JA40T (97.8 % 16S rRNA gene sequence similarity), Pseudoxanthomonas sangjuensis 5GH38-5T (97.7 %) and Pseudoxanthomonas daejeonensis TR6-08T (97.1 %). Growth of strain roo10T occurred at pH ranging from 7 to 9. The temperatures for growth ranged from 20 to 37 oC. NaCl tolerance was obs...
