Soybean membranes possess high‐affinity binding sites for fungal β‐glucans that elicit phytoalexin synthesis. The ability of 1,3‐1,6‐β‐glucans, released by acid hydrolysis from mycelial walls Phytophthora megasperma f.sp. glycinea , to compete the putative elicitor receptors increases with their average degree polymerization (DP). results suggest a function where probability glucan fragments containing structural determinant is optimal approaches 1 as DP tends infinity. Ligand displacement...

A putative receptor protein for a hepta-beta-glucoside phytoalexin elicitor was identified by photoaffinity labeling of detergent-solubilized proteins from soybean root membranes. Incubation partially purified beta-glucan-binding with photolabile 125I-labeled 2-(4-azidophenyl)ethyl-amino conjugate the heptaglucoside elicitor, followed irradiation ultraviolet light (366 nm) resulted in specific 70-kDa band SDS/PAGE. Half-maximal inhibition 125I-labeling underivatized achieved 15 nM...

Soybean membranes contain high‐affinity binding sites for fungal β‐glucans. These may play a role in the recognition by soybean tissues of phytoalexin elicitors. We have solubilized β‐glucan‐binding activity from microsomal using two C 12 ,‐alkyl zwitterionic detergents, Zwittergent 3‐12 (ZW 3‐12) and lysolecithin analog l‐dodecyl‐2‐deoxy‐phosphorylcholine (ES12H). The displayed identical affinity β‐glucans as that found ( K d = 11‐34 nM). Detergent‐protein micelles with glucan eluted...

Abstract The platinum‐catalyzed hydrosilylation of allyl chloride with trichlorosilane was investigated in an ionic liquid‐organic biphasic reaction mode. After liquid screening and repetitive batch mode experiments, the process realized a continuous using loop reactor concept integrated separation recycling catalyst phase. could be operated for 48 h at constant activity selectivity without addition platinum indicating that leaching into product phase far below 1 ppm.

Abstract Der Einsatz von Zeolithen in der adsorptiven Abluftreinigung und Lösungsmittel‐Rückgewinnung scheiterte bisher daran, daß handelsübliche Zeolithe bevorzugt Wasserdampf adsorbieren. Durch spezielle Synthesen oder Dealuminierungsverfahren können hergestellt werden, die extrem hydrophob, hoch temperaturbeständig säurestabil sind. Diese sind daher geeignet, selektiv organische Lösungsmittel aus feuchten Abluftströmen zu Die Unbrennbarkeit verhindert Selbstentzündung des Adsorbens....
