Differential scanning calorimetry (DSC) is used to evaluate the thermal stability and reversibility after heat treatment of transitions associated with various cellular components of Escherichia coli and Lactobacillus plantarum. The reversibility and the change in the thermal stability of individual transitions are evaluated by a second temperature scan after preheating in the DSC to various te...
When a sample material is subjected to a linear temperature program, the heat flow rate into the sample i s proportional to its instantaneous specific heat. By recording this heat flow rate as a function of temperature, and comparing it with the heat flow rate into a standard material under the same conditions, the specific heat of the sample i s determined as a fundion of temperature. The meth...
Trypsin is a serino-protease with a polypeptide chain of 223 amino acid residues and contains six disulfide bridges. It is a globular protein with a predominance of antiparallel -sheet and helix in its secondary structure and has two domains with similar structures. We assessed the stability of -trypsin in the acid pH range using microcalorimetric (differential scanning calorimetry) technique...
Detailed knowledge of thermal conversion processes becomes increasingly important in order to formulate mathematical models for the design and optimization of chemical reactors employed in energy and chemicals recovery from biomass. Since heat of reaction has an important influence on the course of thermal conversion, the corresponding kinetic models should be coupled with heat transfer equatio...
