Use of an isothermal microcalorimetry assay to characterize microbial oxalotrophic activity.
Isothermal microcalorimetry (IMC) has been used in the past to monitor metabolic activities in living systems. A few studies have used it on ecological research. In this study, IMC was used to monitor oxalotrophic activity, a widespread bacterial metabolism found in the environment, and particularly in soils. Six model strains were inoculated in solid angle media with K-oxalate as the sole carb...
متن کاملStandards in Isothermal Microcalorimetry
The main calorimetric principles used in isothermal microcalorimetry are briefly discussed. Different chemical calibration and test reactions are discussed, with a focus on reactions suitable for ambient conditions: reactions initiated by mixing of liquids (including titration microcalorimetry), dissolution of solid compounds and of slightly soluble gases, a photochemical process, and thermal p...
متن کاملIsothermal microcalorimetry in applied biology
Techniques of isothermal microcalorimetry have been much improved during the past two decades. In addition to their use in fundamental research, applications of practical importance have been established in some areas. However, no significant use of isothermal microcalorimetry has yet been seen in practical applications of biology, despite many methodological studies reported from that area. Th...
متن کاملQuantitative Characterization of sorption through isothermal microcalorimetry
inTroDuCTion When a problem is encountered in the production or storage of solid dosage forms, invariably the problem is somehow connected to the sorption of water. In the presence of water, the physical properties of solids may be altered causing changes in flow properties, free volume, and compressibility; or there may be an accelerated interconversion between polymorphic forms seriously affe...
متن کاملThe use of isothermal heat conduction microcalorimetry to evaluate drug stability in tablets.
Isothermal heat conduction microcalorimetry was used to evaluate chemical stability of a solid drug in tablets. A variety of mixtures were compressed to flat faced tablets of 300 mg weight and 10 mm diameter. The content of drug amounted to 10%. Besides drug containing tablets, also placebo tablets as well as the non compressed mixtures were examined by microcalorimetry at 80 degrees C. The exc...
