Antifungal and antibacterial functions of medicinal leech recombinant destabilase-lysozyme and its heated-up derivative

PISKUNKOVA, I. B. PAVLOVA, L. L. ZAVALOVA, I. P. BASKOVA

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2,   Pages 203-209 doi: 10.1007/s11705-012-1277-2

Abstract: Antifungal activity of recombinant medicinal leech destabilase-lysozyme (rec.Dest-Lys) was investigated by using fungi: , and , including yeasts and . Its antibacterial activity was investigated on gram-negative bacteria . These activities were assessed by radial agar diffusion assay, and scanning and transmission electron microscopy. Therefore, destabilase-lysozyme not only is endo-isopeptidase and lysozyme, but also has antifungal and antibacterial activities. Muramidase activity of rec.Dest-Lys disappeared after heat-treating at 90°C for 50 min without the loss of its antimicrobial activity. Furthermore we showed for the first time that the heated-up derivative of rec.Dest-Lys exhibited more potent activities against the above enumerated fungi and gram-negative bacteria than original protein.

Dual enzyme activated fluorescein based fluorescent probe

Maria L. Odyniec, Jordan E. Gardiner, Adam C. Sedgwick, Xiao-Peng He, Steven D. Bull, Tony D. James

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1,   Pages 117-121 doi: 10.1007/s11705-018-1785-9

Abstract: A simple dual analyte fluorescein-based probe ( ) was synthesised containing -glucosidase ( -glc) and hydrogen peroxide (H O ) trigger units. The presence of -glc, resulted in fragmentation of the parent molecule releasing glucose and the slightly fluorescent mono-boronate fluorescein ( ). Subsequently, in the presence of glucose oxidase (GOx), the released glucose was catalytically converted to D-glucono- -lactone, which produced H O as a by-product. The GOx-produced H O resulted in classic H O -mediated boronate oxidation and the release of the highly emissive fluorophore, fluorescein. This unique cascade reaction lead to an 80-fold increase in fluorescence intensity.

Utilisation of waste heat from exhaust gases of drying process

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 1,   Pages 131-138 doi: 10.1007/s11705-016-1560-8

Abstract: Nowadays a lot of low-grade heat is wasted from the industry through the off- and flue-gasses with different compositions. These gases provide the sensitive heat with utilisation potential and latent heat with the components for condensation. In this paper, process integration methodology has been applied to the partly condensed streams. A hot composite curve that represents the gas mixture cooling according to equation of state for real gases was drawn to account the gas-liquid equilibrium. According to the pinch analysis methodology, the pinch point was specified and optimal minimal temperature difference was determined. The location of the point where gas and liquid phases can be split for better recuperation of heat energy within heat exchangers is estimated using the developed methodology. The industrial case study of tobacco drying process off-gasses is analysed for heat recovery. The mathematical model was developed by using MathCad software to minimise the total annualised cost using compact plate heat exchangers for waste heat utilisation. The obtained payback period for the required investments is less than six months. The presented method was validated by comparison with industrial test data.

A Standard for the Commissioning Process

William L. Gillis,Elizabeth A. Cudney

Frontiers of Engineering Management 2015, Volume 2, Issue 1,   Pages 39-51 doi: 10.15302/J-FEM-2015006

Abstract: The demand for commissioning services for new-building construction projects is experiencing rapid growth. Commissioning (Cx) is touted as being a quality-focused process for ensuring the owner’s project requirements (OPR) are met by design, final construction, and the operations of a building. To an owner this is just what is needed to receive a perfect building at occupancy. However, as many owners have realized, the Cx process does not guarantee the completed building will be what was expected. It should be pointed out that this is typically not caused by the Cx process, but the Cx process should or could have identified, in the early phases of the project, many of the issues that made it through to the completed building. There are a number of reasons why the Cx services received may not be optimal. Often it is poor communication and the transfer of knowledge between project teams. Cx should and can facilitate both communication and the transfer of knowledge from phase to phase. An adaptation of the quality function deployment (QFD) four-phase model can accomplish this by filling the gaps among the major Cx activities and provide a standard approach to the process. The four-phase model effectively links each of the Cx activities to each other and back to the OPR, providing a method for improved communication and knowledge transfer. This paper investigates some potential reasons for inconsistent Cx services, presents an argument for the need of a Cx standard, and proposes a potential standard.
