H.H. Beltman: Natuursteencollecties deel 7
No full textDeel 6 over natuursteencollecties ging over de collectie ir. J.H. Beltman bij het Mineralogisch-Geologisch Museum (MGM) van de TU Delft en hoe deze collectie met 222 marmers terug te voeren valt op de steenhouwerij en machinale fabriek van marmerwerken H.H. Beltman uit Deventer. In deel 7 gaat universitair docent Heritage & Technology en natuursteenspecialist Wido Quist van de TU Delft dieper in op dit bedrijf aan de hand van een in 1907 opgemaakte inventaris van het hele bedrijf en ook op het tweede deel van de inventaris van de collectie.Heritage & Technolog

Comparisons of α-amylase inhibitors from seeds of common bean mutants extracted through three phase partitioning
No full textThis study compared the inhibitory activity of α-amylase inhibitor (αAI) extracted from common bean (Phaseolus vulgaris L.) variety Hwachia, its nine mutants and two introduced varieties by using three-phase partitioning (TPP). A commercially prepared Phase 2 was also used to serve as a comparative reference. The optimal purification parameters for TPP were 30% saturation ammonium sulphate and pH 5.25. Considerable variations were detected in αAI content, total inhibitory activity and specific inhibitory activity of αAI purified from different common beans. Mutant SA-05 had the αAI inhibitory activity of 6267 units g−1 dry seed weight, which was higher than Hwachia (5062 units g−1 dry seed weight) and Phase 2 (3200 units g−1 dry weight). Moreover, it had an extremely lower IC50 (0.40 μg) than Phase 2 (10.22 μg). Thus, the mutant SA-05 may be used as raw material in commercial preparation of αAI extracts for controlling appetite and energy intake
