Micropatterning of surfaces with varying chemical, physical and topographical properties usually requires a number of fabrication steps. Herein, we describe a micropatterning technique based on plasma enhanced chemical vapour deposition (PECVD) that deposits both protein resistant and protein repellent surface chemistries in a single step. The resulting multifunctional, selective surface chemis...
douala metropolitan city loated in the littoral province of cameroon,has experienced a rapid urbaniation and industralisation. the city depends heavily on groundwater as a resource. due to ubiquitous sources of pollution, groundwater quality and contamination has become an imprtant issue for this urban groundwater supply. this study uses the major ion chemistry of groundwater together with t...
A new thiazolyl peptide, kocurin (1), was isolated from culture broths of a marine-derived Kocuria palustris. Its structural elucidation was accomplished using a combination of spectroscopic and chemical methods, including HRMS, extensive 1D and 2D NMR analysis, MS/MS fragmentation, and chemical degradation and Marfey's analysis of the resulting amino acid residues. The structure herein reporte...
Lipiarmycin, a metabolite of Actinoplanes deccanensis nov. sp. (PARENTI et al.), has been isolated in pure form. It has a molecular formula C52 CONGRUENT TO 54H74 CONGRUENT TO 76Cl2O19, (M.W. = 1,073 CONGRUENT TO 1,099). From its chemical and physico-chemical characteristics, lipiarmycin can be considered a new antibiotic. Lipiarmycin is highly active against Gram-positive bacteria, includin...
We investigated bioavailability, as measured by the biota-sediment accumulation factor (BSAF), of reversibly sorbed and desorption-resistant phenanthrene to the deposit-feeding freshwater tubificid oligochaete Ilyodrilus templetoni. Desorption-resistant, phenanthrene-contaminated sediments were prepared by a sequential batch desorption method by washing with an isopropanol solution. The BSAFs a...
