Oxygen microgradients in the rhizosphere of the mangrove Avicennia marina
Oxygen concentration was measured in aerial roots (pneumatophores), horizontal cable roots and surrounding sediment of the tree Avicennia marina (Forsk.) Vierh. in a mangrove swamp at Ao Nam Bor, on the southeast coast of Phuket Island, Thailand. The O2 measurements were made in the field with a polarographlc oxygen minielectrode. The O2 concentration inside pneurnatophores was 63 to 88 % of ai...
متن کاملBiosynthesis of Titanium Dioxide Nanoparticles from the Mangrove (Avicennia marina) and Investigation of its Antibacterial Activity
Background and purpose: Development of biocompatible and nontoxic methods for synthesis of nanoparticles is important in bio-nanotechnology. This study aimed at biosynthesis of titanium dioxide nanoparticles (TiO2 NPs) using leaf of the native mangrove (Avicennia marina) and investigating its antibacterial activity. Materials and methods: Effect of four different solutions composed of dry extr...
متن کاملIridoids from Avicennia marina.
Three new iridoid glucosides, 10-O-[(E)-cinnamoyl]-geniposidic acid, 10-O-[(E)-p-coumaroyl]-geniposidic acid, 10-O-[(E)-caffeoyl]-geniposidic acid and the known iridoid glucoside, 2'-O-[(E)-cinnamoyl]-mussaenosidic acid have been isolated from Avicennia marina. The structures were determined primarily by NMR spectroscopy. The assignment of NMR signals was performed by means of 1H-1H COSY, HMQC ...
متن کاملThe Chemical Investigations of the Mangrove Plant Avicennia marina and its Endophytes
Abstract: A diverse array of bioactive compounds have been isolated and characterized from the mangrove plant Avicennia marina and its endophytes. Extensive chemical investigations of the different parts (barks, leaves, twigs, etc.) of the mangrove plant A. marina and its endophytes (mainly endophytic fungi) resulted in the reporting of the isolation of 123 compounds, and most of them are new o...
متن کاملInverse relationship between salinity and n-alkane dD values in the mangrove Avicennia marina
Hydrogen isotope ratios in lipids derived frommangroves have the potential to be used for paleohydrologic reconstructions and could serve as a much needed tool for establishing past climate variability in the tropics. We assessed the effect of salinity on the apparent fractionation factor, aa, between mangrove derived n-alkanes and their source water for Avicennia marina (gray mangrove) specime...
