The activation of alkM is reported to occur within 30 min post-exposure to alkanes, when significant alkane degradation occurs 66,74 . The alkane molecules accumulated on cell membrane or internalized inside A. baylyi cells were therefore hypothesized to be rapidly consumed.…”

Alkanes are one of the most widespread contaminants in the natural environment, primarily as a consequence of biological synthesis and oil spills. Many indigenous microbes metabolize alkanes, and the chemotaxis and accumulation in some strains has been identified. For the first time, we apply Raman microspectroscopy to identify such chemotaxis-related affinity, and quantify the alkane concentrations via spectral alterations. Raman spectral alterations were only found for the alkane chemoattractant bacteria Acinetobacter baylyi ADP1, not for Pseudomonas fluorescence,

However, if "naked" nanoparticles are used, the presence of magnetic interactions, especially dipolar interactions, produces agglomeration, clustering and subsequent precipitation [8].…”

Changes on structural and magnetic properties of maghemite nanoparticles during their coverage with MCM-41, Ceramics International, http://dx.doi.org/10.1016/j.ceramint. 2015.08.016 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Mössbauer spectroscopy at 25 and -260 ºC and transmission electron microscopy were used to study the magnetic and structural changes of the initial maghemite nanoparticles produced during its coverage with the mesoporous silica structure. The presence of the mesoporous structure inhibits the expected transformation from maghemite to hematite when the system was calcined in air at 510 ºC. It was established that a sintering of the nanoparticles during the calcination step occurs, leading to a magnetization saturation value similar to that of the bulk compound. In order to evaluate the capability as adsorbent, the magnetic composite was subjected to a surface amino-functionalization and then tested for Cr(VI) and Cu(II) adsorption from water.

“…Means of reducing energy consumption throughout all of the fuel life cycle stages are being sought in order to reduce energy consumption and increase the fossil energy ratio: usage of less nitrogen at the algae growth stage (Lardon et al, 2009), at the stage of biomass preparation for fuel production, including oil extraction, replacement of old technologies with new ones and combine several different biomass processing methods (Xu et al, 2011).…”

The article considers the opportunities for reduction of energy consumption in the life cycle of biodiesel obtained from microalgae oil. Results show that by introducing technical glycerol and substrate leftover after production of biogas into the microalgae growth media energy consumption can be significantly reduced. Production of biogas from de-oiled microalgae improves the energy balance of the life cycle of biodiesel obtained from microalgae oil. It is impossible to obtain fuel containing more energy than would be used in the process of production if microalgae for biodiesel production are cultivated in conventional growth media. Only by subjecting microalgal biomass for production of gaseous and liquid biofuel (biodiesel and biogas) the total energy consumption is lower and equals to 65802.
