“…To evaluate alkane bioavailability or bioaccessibility, some whole-cell bioreporters have been developed 16 and even applied in real-world cases 4,17 , but they suffer from relatively low reproducibility. Considering the rapid response required to oil spill incidents, it is necessary to develop some real-time and non-destructive screening tools to achieve fast and reliable detection of crude oil contamination.…”

“…Acinetobacter baylyi is the bacterial species with the strongest alkane chemotaxis and accumulation 16,[24][25][26] . In A. baylyi, the putative gene encoding 4 an MCP is chpA which has high similarity to cheY (fused chemotactic sensory histidine kinase) and ompR (two-component response regulator) in Escherichia coli, suggesting potentially similar chemotaxis machinery. A. baylyi cells have high affinity only to alkane droplets, but not to other hydrophobic molecules 16 , suggesting that the MCP has high recognition specificity to linear alkanes.…”

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,

“…One of the most promising approaches used for the environment monitoring is the application of biosensors (Daniel et al 2008;Palchetti and Mascini 2008;Sorensen et al 2006), including those based on bioluminescent bacteria (Ren 2004;Woutersen et al 2011;Elad et al 2011Elad et al , 2013Ji et al 2013;Zhang et al 2013;Ding et al 2015;Eltzov et al 2015).…”

To assess the ecotoxicological and sanitary situation in two European metropolis, Rostov-on-Don (Southern Russia) and Munich (Southern Germany), wastewaters of the two cities were examined with a panel of bacterial lux-biosensors:The presence of different genotoxic compounds and substances with the oxidative and membrane-damaging effects was revealed in contaminated wastewater with the applied panel of the lux-biosensors. The integral toxicity was approximately the same in both cities but demonstrated opposite trends. The presence of genotoxicants and peroxides was higher in the majority of the Munich wastewater samples. There were also differences in the presence of individual toxicants. The presence of the genotoxic compounds might also promote development and dissemination of several antibiotic resistance traits found in microorganisms, a feature more pronounced in Rostov-on-Don wastewaters. By means of polymerase chain reaction assay, antibiotic resistance genes to such antibiotics as ermB, vim and vanB were revealed in two Munich samples. Antibiotic resistance genes were present at all Rostov samples, and genes ndm, vanA, vanB and ermB were found. Taken together, the proposed analytical approach with the application of the constructed panel of biosensors can be applied for monitoring of the ecotoxicological contamination in the wastewaters of large cities.

“…Different from domestic wastewater, industrial wastewater aggravated the actuality due to the intensive discharge and threats of toxic compounds, such as heavy metals (Boening 2000), crude oil (Chen et al 2013;Zhang et al 2013) and pesticide (Kolpin et al 2002). It therefore caused serious ecological challenges (Burkholder et al 2007) and human health risk (Cantor 1997).…”

This paper investigates a new type of carbonbased electrodes, which were equipped with graphite and activated carbon fiber composite, to improve the performance of electrosorption. The results indicated that the highest desalination efficiency achieved 55 % and the optimal condition was 1.6 V voltage, 60 min retention time and 1.0 cm electrode distance. Freundlich isotherms successfully fitted with the respective behavior of the composite electrode and provided theoretical evidence for the desalination performance improvement. Applied in real black liquor of refined cotton, the graphite and activated carbon fiber composite electrodes achieved high removal efficiency for conductivity (59 %) and COD Cr (76 %). Similar removal performance was also observed in sodium copper chlorophyll wastewater, and removal efficiency was 37 % for conductivity and 14 % for COD Cr . For the first time, this research demonstrated the biodegradability improvement in real industrial wastewater via electrosorption treatment, suggesting a potential pretreatment technique for high-salinity wastewater.
