This study attempts to explore customer satisfaction associated with innovative services in airlines and hotels from a tourist perspective. The number of tourists has doubled in recent years. Tourists engage in more activities, the main ones being long-distance air travel and usage of the hotel for food and stay. As a result, airlines and hotels have become one of the essential contributors in determining customer satisfaction. Today's customer wants to explore and enjoy innovative services apart from their needs. By examining various services provided by airlines and hotels, this study can analyse innovative services. However, innovative services in these sectors have not yet reviewed comprehensively, the method used in this conceptual work based on literature reviews. The proposed hypotheses indicate that innovative airline services may have a significant relationship with customer satisfaction and enhance tourism; innovative hotel services may have a moderating relationship on customer satisfaction and enhance tourism. The study also presented innovative service ideas that could strengthen the tourism sector in the future. © 2020 by Advance Scientific Research.

Impact of innovative services on customer satisfaction and enhancing tourism: Airline and hotel services from tourist perspective

Aim - The rationale behind this review paper is to examine the association between the lean practices and green practices in the service sector. And that raises set of research issues and leading to select some research questions arising out this topic of research. Design/methodology/approach-The articles published in the period of 1999-2020 were collected by different data bases like Elsevier, emerald, Springer, Taylor Francis, the articles were scrutinized and clarified thoroughly close to the relation of lean and green management in service industries. Findings- Combining the lean and green together in the service organization is a daunting task much of the articles are emphasize more on the technologies rather than human efficiency in achieving the sustainability in the lean and green methods, so there is a large scope in the human involvement and the subsequent benefits of LGM(Lean and green management). Research implications/Limitations- There are many more articles e emphasizing the importance of lean implementation, lean management, lean six sigma but very few existing literatures are available only in lean greenmangement, after careful refining of the existing articles related to lean and green management in service industries we exclude many non relevant articles related to other domains (like green construction, green technologies in architecture etc.) based from this 84 articles only. Originality/value- The paper evaluates 84 articles reported in the domain of lean green management, it explores ample opportunities of research potential available in the lean green management in the service industries.

Discovery of mupirocin, an antibiotic that targets isoleucyl-tRNA synthetase, established aminoacyl-tRNA synthetase as an attractive target for the discovery of novel antibacterial agents. Despite a high degree of similarity between the bacterial and human aminoacyltRNA synthetases, the selectivity observed with mupirocin triggered the possibility of targeting other aminoacyl-tRNA synthetases as potential drug targets. These enzymes catalyse the condensation of a specific amino acid to its cognate tRNA in an energy-dependent reaction. Therefore, each organism is expected to encode at least twenty aminoacyl-tRNA synthetases, one for each amino acid. However, a bioinformatics search for genes encoding aminoacyl-tRNA synthetases from Mycobacterium smegmatis returned multiple genes for glutamyl (GluRS), cysteinyl (CysRS), prolyl (ProRS) and lysyl (LysRS) tRNA synthetases. The pathogenic mycobacteria, namely, Mycobacterium tuberculosis and Mycobacterium leprae, were also found to possess two genes each for CysRS and LysRS. A similar search indicated the presence of additional genes for LysRS in gram negative bacteria as well. Herein, we describe sequence and structural analysis of the additional aminoacyl-tRNA synthetase genes found in M. smegmatis. Characterization of conditional expression strains of Cysteinyl and Lysyl-tRNA synthetases generated in M. smegmatis revealed that the canonical aminoacyl-tRNA synthetase are essential, while the additional ones are not essential for the growth of M. smegmatis. © 2016 Ravishankar et al.

Essentiality Assessment of Cysteinyl and Lysyl-tRNA Synthetases of Mycobacterium smegmatis

Conditional expression strains serve as a valuable tool to study the essentiality and to establish the vulnerability of a target under investigation in a drug discovery program. While essentiality implies an absolute requirement of a target function, vulnerability provides valuable information on the extent to which a target function needs to be depleted to achieve bacterial growth inhibition followed by cell death. The critical feature of an ideal conditional expression system is its ability to tightly regulate gene expression to achieve the full spectrum spanning from a high level of expression in order to support growth and near zero level of expression to mimic conditions of gene knockout. A number of bacterial conditional expression systems have been reported for use in mycobacteria. The utility of an isopropylthiogalactoside (IPTG) inducible system in mycobacteria has been reported for protein overexpression and anti-sense gene expression from a replicating multi-copy plasmid. Herein, we report the development of a versatile set of non-replicating IPTG inducible vectors for mycobacteria which can be used for generation of conditional expression strains through homologous recombination. The role of a single lac operator versus a double lac operator to regulate gene expression was evaluated by monitoring the expression levels of β-galactosidase in Mycobacterium smegmatis. These studies indicated a significant level of leaky expression from the vector with a single lac operator but none from the vector with double lac operator. The significance of the double lac operator vector for target validation was established by monitoring the growth kinetics of an inhA, a rpoB and a ftsZ conditional expression strain grown in the presence of different concentrations of IPTG. The utility of this inducible system in identifying target specific inhibitors was established by screening a focussed library of small molecules using an inhA and a rpoB conditional expression strain.

An IPTG Inducible Conditional Expression System for Mycobacteria

In the current study, indigenous bacterial isolates Bacillus subtilis VITSUKMW1 and Escherichia coli VITSUKMW3 from a chromite mine were adapted to 100 mg L-1 of Cr(VI). The phase contrast and scanning electron microscopic images showed increase in the length of adapted E. coli cells and chain formation in case of adapted B. subtilis. The presence of chromium on the surface of the bacteria was confirmed by energy dispersive X-ray spectroscopy (EDX), which was also supported by the conspicuous Cr-O peaks in FTIR spectra. The transmission electron microscopic (TEM) images of adapted E. coli and B. subtilis showed the presence of intact cells with Cr accumulated inside the bacteria. The TEM-EDX confirmed the internalization of Cr(VI) in the adapted cells. The specific growth rate and Cr(VI) reduction capacity was significantly higher in adapted B. subtilis compared to that of adapted E. coli. To study the possible role of Cr(VI) toxicity affecting the Cr(VI) reduction capacity, the definite assays for the released reactive oxygen species (ROS) and ROS scavenging enzymes (SOD and GSH) were carried out. The decreased ROS production as well as SOD and GSH release observed in adapted B. subtilis compared to the adapted E. coli corroborated well with its higher specific growth rate and increased Cr(VI) reduction capacity. © 2013 Springer Science+Business Media Dordrecht.
