phytoextraction phytotransformation and rhizodegradation of ibuprofen associated with Typha angustifolia in a horizontal subsurface flow constructed wetland
Water Research, 2016Co-Authors: Yifei Li, Jiefeng Zhang, Bing Wu, Wun Jern Ng, Adhityan AppanAbstract:Abstract Widespread occurrence of trace pharmaceutical residues in aquatic environments is of great concerns due to the potential chronic toxicity of certain pharmaceuticals including ibuprofen on aquatic organisms even at environmental levels. In this study, the phytoextraction, phytotransformation and rhizodegradation of ibuprofen associated with Typha angustifolia were investigated in a horizontal subsurface flow constructed wetland system. The experimental wetland system consisted of a planted bed with Typha angustifolia and an unplanted bed (control) to treat ibuprofen-loaded wastewater (∼107.2 μg L −1 ). Over a period of 342 days, ibuprofen was accumulated in leaf sheath and lamina tissues at a mean concentration of 160.7 ng g −1 , indicating the occurrence of the phytoextraction of ibuprofen. Root-uptake ibuprofen was partially transformed to ibuprofen carboxylic acid, 2-hydroxy ibuprofen and 1-hydroxy ibuprofen which were found to be 1374.9, 235.6 and 301.5 ng g −1 in the sheath, respectively, while they were 1051.1, 693.6 and 178.7 ng g −1 in the lamina. The findings from pyrosequencing analysis of the rhizosphere bacteria suggest that the Dechloromonas sp., the Clostridium sp. (e.g. Clostridium saccharobutylicum ), the order Sphingobacteriales, and the Cytophaga sp. in the order Cytophagales were most probably responsible for the rhizodegradation of ibuprofen.

Bioma : Berkala Ilmiah Biologi, 2014Co-Authors: Hamdani Abdulgani, Munifatul Izzati, Sudarno SudarnoAbstract:Industrial crackers centers at Kenanga Village has been able to lift the local economy,but that has been polluting the surrounding surface water contamination caused by wastewater discharged directly without any treatment in advance so that the water is black and smells foul . Therefore, the need of alternative wastewater treatment and in the study conducted by the artificial wetlands (constructed wetland) system Sub - surface Flow vertical flow with Typha angustifolia plant and use a medium sized sand 1 mm - 5 mm were previously washed first with media thickness of 30 cm and then operated intermittently using a peristaltic pump 6 times a day with the design of constructed wetlands construction made of wood coated with plastic and reactor dimensions 90 cm x 45 cm x 50 cm . As for the control (no treatment) using use the bucket size diameter 40 cm and height of 20 cm. This study aims to determine the ability of Subsurface Flow Constructed Wetland with Typha angustifolia plants in lowering the concentration of TSS , BOD 5 , COD , ammonia (NH 3 – N) and sulfide (H 2 S) at 5,10 and 15 days of processing .

2013Co-Authors: Hamdani Abdulgani, Munifatul IzzatiAbstract:The existence of industrial centers in Desa Kenanga crackers have been able to lift the local economy, but it negatively impacts the surface water pollution caused by waste water so that the water is black and smells foul. In this study crackers industrial waste water is treated with the artificial wetlands (constructed wetland) system Sub-surface Flow vertical flow intermittently operated using a peristaltic pump 2 times a day with the design of constructed wetlands construction is made of wood covered with plastic and the dimensionless reactor 90 cm x 45 cm x 50 cm. This study aimed to determine the ability of Subsurface Flow Constructed Wetland with Typha angustifolia plants and without plants in lowering the concentration of TSS, Ammonia (NH3-N), and Sulfide (H2S) operating at 1, 2, 3 days. The results showed a decrease in the efficiency of consecutive time 1, 2 and 3 days in Subsurface Flow Constructed Wetland with Typha angustifolia for TSS 69.9%, 76.6%, 79.9%; Ammonia 11.9%, 19.1% ; 33.9%; Sulfide 11.9%, 46.2%, 54.5%, while in the Subsurface Flow Constructed Wetland plants produce no TSS removal efficiency of 66.4%, 73.3%, 76.5%, Ammonia 8.0%, 15.1%, 26.6%; Sulfide 9.7%, 31.2%, 52.9%.

Acetylation and silylation of piperidine solubilized sporopollenin from pollen of Typha angustifolia L.
Zeitschrift fur Naturforschung. C Journal of biosciences, 2003Co-Authors: Friedhelm Ahlers, Jörg Lambert, Rolf WiermannAbstract:Silyl and acetyl derivatives of sporopollenin from the pollen of Typha angustifolia L. were prepared. The derivatized products were readily soluble in piperidine-d11 and could be investigated employing one- and two-dimensional proton and carbon NMR (nuclear magnetic resonance) spectroscopy (1H,1H-COSY and 13C,1H-HETCOR techniques). For the first time, a two dimensional 13C,1H-HETCOR NMR spectrum of a sporopollenin could be obtained. The results underline the importance of derivatization techniques for obtaining two dimensional 13C-NMR spectra of sporopollenins. Moreover, piperidine turns out to be a more suitable solvent for sporopollenins than 2-aminoethanol, as it allows for higher solubilities, being important for 2D-NMR investigations. From the HETCOR and COSY spectra of the silylated and the acetylated Typha samples the occurrence of aliphatic polyhydroxy compounds as well as phenolic OH groups became evident.

Continuous decomposition of sporopollenin from pollen of Typha angustifolia L. by acidic methanolysis.
Zeitschrift fur Naturforschung. C Journal of biosciences, 2002Co-Authors: H Bubert, Friedhelm Ahlers, Jörg Lambert, Stefan Steuernagel, Rolf WiermannAbstract:Sporopollenin from the pollen of Typha angustifolia L. was exposed to a series of 36 subsequent acidic methanolysis procedures. The remaining decomposition products were investigated using several spectroscopic methods including Fourier transform infrared spectroscopy (FT-IR), solid state 1 3 C nuclear magnetic resonance spectroscopy ( 1 3 C-CPMAS-NMR) and X-ray photoelectron spectrometry (XPS). Substantial weight losses of the sporopollenin material occur after each acidic methanolysis step, while FT-IR and 1 3 C-CPMAS-NMR spectra display no noticeable differences after 12, 24 and 36 steps. These findings are interpreted as a hint that the sporopollenin polymer has a uniform composition, i.e. relatively small monomer moieties of similar primary structure are present. Moreover, the weight losses account for the presence of substantial amounts of ether linkages in the sporopollenin polymer.

The nature of oxygen in sporopollenin from the pollen of Typha angustifolia L.
Zeitschrift fur Naturforschung. C Journal of biosciences, 2000Co-Authors: Friedhelm Ahlers, H Bubert, Stefan Steuernagel, Rolf WiermannAbstract:Native and peracetylated sporopollenin from the pollen of Typha angustifolia L. was investigated using several spectroscopic methods, inducing Fourier transform infrared spectroscopy (FTIR), solid-state 13C-nuclear magnetic resonance spectroscopy (13C-NMR) and X-ray photoelectron spectrometry (XPS). Interpretation of the experimental data shows that the greater part of oxygen found in sporopollenin originates from hydroxyl groups and must be derived from aliphatics and not from aromatics. This result indicates that not only aromatics and long unbranched aliphatics but also poly-hydroxyl aliphatic components are involved in the complex structure of the polymer. Furthermore, it is most probable that the monomers of the sporopollenin skeleton are linked by ether- and not by ester-linkage. Two possible approaches are suggested for the characterisation of sporopollenin structure.

1H NMR analysis of sporopollenin from Typha angustifolia
Phytochemistry, 1999Co-Authors: Friedhelm Ahlers, Ina Thom, Jörg Lambert, Rüdiger Kuckuk, Rolf WiermannAbstract:Abstract The first analysis of sporopollenin using 1H NMR-techniques revealed the presence of four phenolic compounds in different amounts. The phenolic compounds are tri- or tetrasubstituted. The sporopollenin was isolated and purified from Typha angustifolia by an enzymatic procedure, followed by extraction with organic solvents.
