The growth, covalent functionalization, and subsequent DNA modification of gallium phosphide (GaP) nanorods is presented. Analysis of the nanorods by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) revealed important information regarding their physical properties such as the presence of twinning defects. The nanorods were deposited onto g...

background: l-glutamic acid is one of the major amino acids that is present in a wide variety of foods. it is mainly used as a food additive and flavor enhancer in the form of sodium salt. corynebacterium glutamicum (c. glutamicum) is one of the major organisms widely used for glutamic acid production. methods: the study was dealing with immobilization of c. glutamicum and mixed culture of c. g...

bacteriorhodopsin (br) is a retinal protein that is a light-driven proton pump and has an important role in photosynthesis in archaebacterium halobacterium salinarum. the br molecule absorbs light and photochemical changes occur in it, and different intermediates will be produced in its photochemical cycle that some of them like p and q intermediates have a long half-life. there have been many ...

aacel9a [β-1,4-endoglucanase, (e.c:3.2.1.4)], was immobilized onto glutaraldehyde activated chitosan macrosphere by covalent attachment. the properties of the immobilized aacel9a were investigated by determining the optimum ph and optimum temperature for activity, thermal stability, and kinetic parameters. the immobilization process shifted the enzyme’s optimum temperature from 65 °c for the fr...
