In a liquid-liquid interface bioreactor, fungal cells locate in a hydrophilic polyacrylonitrile microsphere layer on an aqueous-organic interface. In this article, effects of hydrophobicity of the interface on n-decane hydroxylation activity of Monilliera sp. NAP 00702 was examined. (-)-4-Decanol production was significantly enhanced to 132% by addition of polytetrafluoroethylene.

Monophasic oxides of the formula, Ba!_xPbxTiO3 (0 < x < 1:0) were obtained at temperatures close to 500 8C from polymeric precursors formed using citric acid and ethylene glycol. These oxides were found to be tetragonal for all values of x, the distortion increasing with Pb content. Differential scanning calorimetry (DSC) shows that the decomposition of the precursor to the oxides varies with c...

Manganese dioxide (MnO2) is a Mn deposit widely accumulated in the corrosion layer of pipelines, and iodide (I−) halogen ion frequently detected waters. The biofilm dwelling on scales often secretes extracellular polymeric substances (EPS) into drinking water. paper aimed to study I− oxidation by MnO2 iodinated disinfection byproducts (I-DBPs) formation with EPS as precursor. More than 93% form...
