Utilization of various hydrocarbons by microbes is well known (Beerstecher, 1954), but little has been reported on the cellular composition of hydrocarbongrown cells. No doubt it has been assumed that these cells differ little from those cultivated on nonhydrocarbon substrates and, in general, this assumption is probably true. But it is recognized that substrates and cultural conditions can inf...

We studied the microbial diversity of benthic cyanobacterial mats inhabiting a heavily polluted site in a coastal stream (Wadi Gaza) and monitored the microbial community response induced by exposure to and degradation of four model petroleum compounds in the laboratory. Phormidium- and Oscillatoria-like cyanobacterial morphotypes were dominant in the field. Bacteria belonging to different grou...

Phase interfaces in melting and solidification processes are strongly affected by the presence of convection in the liquid. One way of modeling their transient evolution is to couple an incompressible flow model to an energy balance in enthalpy formulation. Two strong nonlinearities arise, which account for the viscosity variation between phases and the latent heat of fusion at the phase interf...

a simple, highly sensitive, accurate and selective method for determination of trace amounts of cu2+ in water samples was reported. in this paper, isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (iide) in order to prepare an effective sorbent for the preconcentration and determination of cu. the sorption capacity of isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (ii...

Abstract The self-assembly of cellulose nanowhiskers (CNWs) in confined geometries provides a powerful method for the fabrication novel structures. Herein, ordered honeycomb microporous films were first prepared with surface-acylated CNWs (CNWs-SU) through breath figure method. Resulting showed highly porous order over large regions and iridescent color was only displayed by their rims, which i...

Oil spillages lead to the formation of hydrocarbon and metal mixtures possessing effects on alkane-degrading bacteria that are responsible for bioremediation oil-contaminated soils waters. Studies bacterial responses mixture petroleum can inform appropriate strategies bioremediation. We employed a luminescent bioreporter Acinetobacter baylyi ADPWH_recA with alkane degradation capability evaluat...
