Although there are many reports demonstrating that thiobacillus denitrificans (TDN) may inhibit corrosion caused by sulfate-reducing bacteria (SRB), very little is known for the inhibition effect in crude petroleum. In this work, the inhibition effect of TDN on the corrosion of X70 pipeline steel caused by SRB in crude petroleum was studied. The optimum incubation condition of TDN was obtained by orthogonal experimentation. The growth characteristics of TDN and SRB in crude petroleum were reflected via analyzing the transformation of sulfur. The inhibition effect on corrosion of X70 pipeline steel in crude petroleum was analyzed by an X-ray energy dispersive spectrometer in conjunction with weight loss measurement. The results suggested that TDN could effectively inhibit SRBinvolved corrosion by biologically oxidizing sulfide to sulfate in crude petroleum.

“…LG oil showed aggregation and deformities [45]. Korenblum et al also stated that both LG oil and its major component, citral showed an immediate killing effect against sulfate reducing bacteria, suggesting that citral was responsible for the antibacterial activity of LG oil [46]. The SEM micrographs explains that the LGME-AZM formulation in comparison with the pure drug AZM has an enhanced antibacterial property against pathogenic bacterial strains.…”

Objective: Azithromycin (AZM), an azalide drug is used to treat bacterial infections. It is poorly water-soluble, with low human bioavailability due to partial absorption. This can be improved using a microemulsion drug delivery system using essential oil.Methods: Microemulsion system was prepared with AZM solubilized lemongrass oil (Cymbopogon citratus), Tween 20 and water containing 1% (v/v) 10 mmol sodium hydroxide. In vitro drug release was determined using a 14KDa semipermeable dialysis membrane. The kinetics of bacterial killing was done at MIC concentrations, and viable counts were determined hourly for 24 h. Bacterial cell viability was determined by differential staining with acridine orange and ethidium bromide. In vitro toxicity was determined by the MTT assay, while in vivo toxicity was determined in male Wistar rats.Results: The optimized formulation (5:20:75 %) was thermodynamically stable with drug solubility of 366.90 mg/ml and a droplet diameter of 12.4±3.9 nm, which do not show in vivo or in vitro toxicity. In vitro drug release study in simulated body fluids revealed a controlled drug release from microemulsion-based formulation. The MIC was 1μg/ml and 2μg/ml against Staphylococcus aureus and Escherichia coli respectively. In vitro kill kinetics showed>2 log10 killing by 8 h. Bacterial cell viability assay and scanning electron microscopy analysis further confirmed substantial morphological changes due to alteration in the cell membrane.Conclusion: The reduced droplet size and the inherent antibacterial property of lemongrass oil enhanced the efficacy of the AZM loaded ME system in comparison with the bulk drug, against the bacterial pathogens.

“…Essential oils are incorporated into these films because they contain phenolic compounds with antibacterial and antifungal activities (Korenblum et al ., ; Jo et al ., ). Among essential oils, lemongrass ( Cymbopogon citratus ) oil (LE) has been incorporated into the edible films such as gelatin and alginate‐apple puree film to provide the antimicrobial activity (Rojas‐Grau et al ., ; Ahmad et al ., ; Tongnuanchan et al ., ).…”

Flaxseed meal protein (FMP) films were prepared, and their mechanical properties (tensile strength (TS) and elongation at break (E) values), water vapour permeability, optical properties and thermogravimetric analysis were evaluated. Briefly, 5 g FMP, 2 g fructose and 0.03 g ferulic acid were required for the optimal preparation of an FMP film. The TS and E values of the FMP film were 13.12 MPa and 61.90%, respectively. Furthermore, different amounts of lemongrass oil (LE) were incorporated into the FMP film to prepare an antimicrobial film. Wrapping pen shell adductor muscle with the FMP film containing 1.0% LE reduced the counts of inoculated Listeria monocytogenes and Escherichia coli O157:H7 compared with those in the control, after storage at 4°C for 12 day. Consequently, packaging with FMP film containing 1.0% LE can be useful in improving the quality of pen shell adductor muscle during storage.
