主 题：Polycyclic aromatic hydrocarbons Transmembrane transport Adsorption and uptake of hydrocarbons Proteomics Functional regulation of membrane protein Single cell analysis technology
摘 要：In recent years,increasing research has been conducted on transmembrane transport processes and the mechanisms behind the microbial breakdown of polycyclic aromatic hydrocarbons(PAHs),including the role of membrane proteins in transmembrane transport and the mode of *** article explains the adsorption,uptake and transmembrane transport of PAHs by bacteria,the regulation of membrane protein function during the transmembrane *** are three different regulation mechanisms for uptake,depending on the state and size of the oil droplets relative to the size of the microbial cells,which are(i)direct adhesion,(ii)emulsification and pseudosolubilization,and(iii)interfacial ***,two main transmembrane transport modes are introduced,which are(i)active transport and(ii)passive uptake and active efflux ***,introduce the proteomics and single cell analysis technology used to address these areas of research,such as Isobaric tags for relative and absolute quantitation(iTRAQ)technology and Nano Secondary ion mass spectrometry(Nano-SIMS).Additionally,analyze the changes in morphology and structure and the characteristics of microbial cell membranes in the process of transmembrane ***,recognize the microscopic mechanism of PAHs biodegradation in terms of cell and membrane proteins are of great theoretical and practical significance for understanding the factors that influence the efficient degradation of PAHs contaminants in soil and for remediating the PAHs contamination in this area with biotechnology.
