This paper presents an optosensor for screening of four polycyclic aromatic hydrocarbons: anthracene (ANT), benzo[a]pyrene (BaP), fluoranthene (FLT), and benzo[b]fluoranthene (Bbf) using a photomultiplier device with an artificial neural network as transducer. The optosensor is based on the on-line immobilization on a non-ionic resin (Amberlite XAD-4) solid support in a continuous flow. The det...

A new complex of anti-Gram-positive antibiotics was produced by the fermentation of Actinoplanes arizonaensis sp. nov. The antibiotics were recovered from the fermentation broth with Amberlite XAD-7 resin and from the mycelium by acetone lysis. UV, IR, MS and NMR spectral studies characterized these compounds as kalafungin-type antibiotics. They differ from other known members by an unusual oxi...

Ca2+-pump of sarcoplasmic reticulum was partially purified and solubilized with Triton-X100 in the presence of excess phospholipids. Vesicles were reconstituted by removal of Triton with Amberlite XAD-2 and the subsequent freeze-thaw/sonication method (Kasahara, M. and Hinkle, P. C. (1977) J. Biol. Chem., 252: 7384-7390). In the reconstituted system, H+ was ejected during Ca2+ uptake and in the...

That phosphonium-type ionic liquids (ILs) can be used for preparation of novel solid-phase extractants has been shown. The conditions of IL immobilization on the different matrices (polyacrilonitrile, Amberlite XAD-7, hyper cross-linked polystyrene, and multi-walled carbon nanotubes) were determined. The solid-phase extraction of Pt(IV) from 1-2 M HCl and Pu(IV) from 3 M HNO(3) has been investi...

Knowledge of N-nitrosamine precursors from dissolved organic matter (DOM) is important for water professionals to better control N-nitrosamine formation. The characterization of DOM from the Luan River in Northern China was conducted using Amberlite XAD resins and ultra-filtration methods. N-nitrosamine formation potentials were investigated for various DOM fractions. The removal of the DOM dur...

Antilisterial bacteriocin producing strain were isolated from milk samples and subjected to 16S rRNA sequencing found be of genus Enterococcus faecium. The ALC102 partially purified by Amberlite XAD-16 adsorption followed column chromatography. biofilm formation capacity Listeria monocytogenes MTCC 657 evaluated tube method CV binding assay. Biofilm on different abiotic substrates also evaluate...
