Blue green algae was isolated from fresh water bodies of Allahabad region, Yamuna River, India to produce biodiesel. Based on rate of growth in cultural media and morphological characters and biomass production, 8 colonizing blue green algae isolates were selected for the further biofuel production work. To further narrow down the number of isolates, the carbonic anhydrase enzyme assay was used...

This study demonstrates the spectral data for two triarylmethane dyes, malachite green (MG) and crystal violet (CV) at room temperature. Effects of micellar environment, and crown ether addition on the spectral behaviour of the dyes were studied using absorption spectroscopic method. The dye-anionic surfactant interactions in micellar media were investigated. The chosen surfactants with differe...

Bulk quantities of polypyrrole nanofibers and nanospheres can be synthesized with a facile, one-step "green-nano" chemical oxidative polymerization approach, by simply using different reaction media.

Deep eutectic solvents (DESs), as a novel class of green solvents, were successfully applied as eco-friendly and sustainable reaction media for fast surface modification of spherical porous silica, resulting in stationary phases for high-performance liquid chromatography. The new reaction media were advantageous over organic solvents in many aspects, such as the high dispersibility of silica sp...

β-cyclodextrin sulfuric acid as a green lewis acid catalyst has been applied for the preparation of bis(indolyl)methanes, tris(indolyl)methanes and 3,3'-diindolyloxindole derivatives by the condensation of indoles with various carbonyl compounds in aqueous media with high to excellent yields.

We assessed the total energy required to manufacture, install and maintain an extensive, sedumplanted green roof over its assumed life of 20 years in the Mid-Atlantic region of the U.S. using the method of emergy analysis. We estimated its environmental benefits as the sum of summer electricity savings due to cooler building temperatures, primary production of biomass and reduction in intensity...

Detection of Salmonella enteritidis in the environment of commercial laying hens is critical for reducing the production of contaminated eggs by infected flocks. In the present study, an inexpensive and portable electrostatic air sampling device was used to collect S. enteritidis in rooms containing experimentally infected laying hens. After hens were orally inoculated with a phage type 13a S. ...
