Since the discovery that RNA could play important gene regulatory functions in the physiology of a cell, small regulatory RNAs (sRNAs) have been at the center of molecular biology studies.
RNA represents one of the most abundant macromolecules in both eukaryotic and prokaryotic cells. Our results suggest that these surface active compounds can maneuver applications in environmental bioremediation and agriculture, pharmaceuticals and food as functional biomaterials. The utilization of lubricating oils can address waste disposal problem and offer an economical feasible approach for bacterial production of surface active compounds.
Scanning Electron Microscopy has given detailed insight into the microstructural difference of the compounds. The variation between both strains in utilization of hydrocarbons can be manifested in chemical structural differences and properties of the produced surface active compounds. The contrasting nature of bacterial strains in utilization of different hydrocarbons of waste mineral lubricating oils was observed in Gas Chromatography-Mass Spectroscopy analysis. Characterization analysis by Ultraviolet Visible spectrophotometry, Fourier transform infrared spectroscopy, Nuclear Magnetic Resonance spectroscopy, Carbon–Hydrogen–Nitrogen analysis has given detailed structural elucidation of surface active compounds. The comparison between bacterial strains (Gram-positive Bacillus stratosphericus A15 and Gram-negative Ochrobactrum pseudintermedium C1) on utilization of pure straight chain hydrocarbons, waste mineral lubricating oils as sole carbon source and chemical characterization of the synthesized surface active compounds were studied. Such a phenomenon is mediated by production of extracellular polymers which can function as eminent surface active compounds based on their surfactant or emulsifying nature. Bacteria can emulsify or lower surface tension between phases of immiscible substrates and can acquire them as their carbon and energy sources. However, indiscriminate dumping of these used oils have resulted in polluting the natural reservoirs which subsequently destroys ecological balance. Mineral lubricating oils are widely used in various industrial sectors for their applications in maintenance and functioning of machineries. coli afterĮxposure to light due to the production of reactive oxygen species. Superhydrophilicity of the surface and enhanced inhibitory effect on E. Therefore, nanotubes induce the photoinduced coli (η = 25.4%) under UV-Visible light than the darkĬonditions (η = 4.1%). Furthermore, in theĪntibacterial tests performed via the direct contact method, shown a considerable

The surface free energy of the FTO increases from 69.91mN/m (clean FTO) toĨ1.43mN/m after nanotube deposition and irradiation. It reaches 0.00° after irradiation under ultraviolet light. The water contact angle decreases from 37.85° (clean FTO) to 9.53° afterĭeposition of the nanotubes. Microscopy showed that the roughness of the films is superior to the roughness of Raman analysis, X-ray Diffraction, and ScanningĮlectron Microscopy confirmed the deposition of the nanotubes. Glass and sodium titanate nanotubes decorated with TiO2 were synthesized via The films were deposited by electrophoretic deposition technique on FTO Nanotubes decorated with TiO2 films and evaluate the antibacterial activity under UVVis Here, The present work aimed to investigate the wettability of the sodium titanate
