BACKGROUND： Polyhydroxyalkanoates are a good substitute for synthetic plastic because they are highly biocompatible, ecofriendly, and biodegradable. Bacteria in freshwater bodies such as rivers, tube wells, and canals are exposed to alternating high and low concentrations of substrates that induce PHA production. METHODS： Fresh water samples were collected for isolation of bacterial strains. Screening of PHA in bacterial cells was performed with Sudan and Nile Red staining. Extracted PHA was characterized by FTIR. RESULTS： In this study, nine bacterial isolates were selected for PHA production on the basis ofphenotypic screening. Their ability to accumulate PHAs was determined using different monosaccharides and disaccharides. Two bacterial isolates Bacillus cereus T1 （KY746353） and Bacillus cereus R3 （KY746354） produced PHAs. Optimal growth of the bacterial strain （T1） was observed in the presence of glucose, followed by maximum production of PHAs （63% PHAs） during the logarithmic phase of growth. B. cereus R3 （KY746354） accumulated 60% PHAs by dry cell weight. CONCLUSION： PHA accumulation was relatively less with fructose, but both strains showed increased production （up to 50%） with sucrose. The polymer produced was characterized by Fourier-transform infrared spectroscopy （FTIR）, which showed that the compound contains short-chain PHAs.

Two after treatment units, selective catalytic reduction （SCR） and continuously regenerating trap （CRT）, were independently retrofitted to a diesel engine, with the objective to investigate their impact on the conversion/reduction （CR） of polycyclic aromatic hydrocarbons （PAHs）. The experiments were conducted under the European steady state cycle （ESC） first without any retrofits to get baseline emissions, and then with SCR and CRT respectively, on the same engine. The particulate matter （PM）-phase PAHs were trapped in fiberglass filters, whereas gas-phase PAHs were collected in cartridges, and then analyzed using a gas chromatograph-mass spectrometer （GC-MS）. Both PM-phase and gas-phase PAHs were greatly reduced with CRT showing respective CR of 90.7% and above 80%, whereas only gas-phase PAHs were abated in the case of SCR, with CR of above 75%. Lower molecular weight （LMW） PAHs were in abundance, while naphthalene exhibited a maximum relative contribution （RC） to LMW-PAHs for all three cases. Further, the CR of naphthalene and anthracene were increased with increasing catalyst temperature of SCR, most likely due to their conversion to solid particles. Moreover, the Benzo[a]Pyrene equivalent （BaPeq） of PAHs was greatly reduced with CRT, owing to substantial reduction of total PAHs.

The title compound was synthesized by the base catalyzed reaction of 5-（（quinolin- 8-yloxy）methyl）-1,3,4-oxadiazole-2（3H）-thione with methyl chloroacetate. The structure was supported by the spectroscopic data and unambiguously confirmed by single-crystal X-ray diffraction studies. It crystallizes from a methanol solution in the triclinic space group Pi with unit cell dimensions a = 7.4509（9）, b = 10.2389（12）, c = 12.2299（15）A, a = 74.771（2）, β = 77.956（2）, 7 = 69.263（2）°, V = 834.98（17） A3 and Z = 2. In order to gain some valuable insights into the molecular structure, the quantum mechanical calculations were performed using both HF and time-dependent density functional theory at the B3LYP/6-31G（d,p） level. The molecular geometry from X-ray determination of the title compound in the ground state has been compared using the Hartree-Fock （HF） and density functional theory （DFT） with the 6-31G（d） basis set. The calculated results show that the DFT and HF can well reproduce the structure of the title compound. The energetic behavior of the title compound was examined using the B3LYP method with the 6-31G（d） basis set. The harmonic vibrational frequencies calculated have been compared with the experimental FTIR and FT-Raman spectra. The restricted Hartree-Fock and density functional theory-based nuclear magnetic resonance （NMR） calculation procedure was also performed, and it was used for assigning the 13C and 1H NMR chemical shifts of the title compound. Moreover, molecular electrostatic potential and thermodynamic parameters of the title compound were investigated by theoretical calculations.
