1. Study of fast pyrolysis of sugarcane bagasse in a bubbling fluidized bed / Estudo da pirolise rapida de bagaço de cana em reator de leito fluidizado borbulhante
The energy content of biomass can be exploited by direct combustion or after conversion by physical, biological and thermochemical processes. Among the thermochemical processes there is the pyrolysis that is an attractive process because it provokes the conversion of solid biomass into liquids products. Such conversion presents many advantages in transport,

2. Rapid differentiation of Mycobacterium xenopi from mycobacteria of the Mycobacterium avium-intracellulare complex by pyrolysis mass spectrometry.
Thirty four cultures of slow growing, Tween-80 negative mycobacteria were analysed by pyrolysis mass spectrometry. The results showed that pyrolysis mass spectrometry could positively distinguish strains of Mycobacterium xenopi from those of the Mycobacterium avium-intracellulare (MAI) complex. Pyrolysis mass spectrometry may be a useful technique for the ra

3. Protein preservation and DNA retrieval from ancient tissues
The retrieval of DNA from fossils remains controversial. To substantiate claims of DNA recovery, one needs additional information on the preservation of other molecules within the same sample. Flash pyrolysis with GC and MS was used to assess the quality of protein preservation in 11 archaeological and paleontological remains, some of which have yielded anci

4. Rapid Differentiation of Closely Related Candida Species and Strains by Pyrolysis-Mass Spectrometry and Fourier Transform-Infrared Spectroscopy
Two rapid spectroscopic approaches for whole-organism fingerprinting of pyrolysis-mass spectrometry (PyMS) and Fourier transform-infrared spectroscopy (FT-IR) were used to analyze a group of 29 clinical and reference Candida isolates. These strains had been identified by conventional means as belonging to one of the three species Candida albicans, C. dublini

5. Development of Amplified 16S Ribosomal DNA Restriction Analysis for Identification of Actinomyces Species and Comparison with Pyrolysis-Mass Spectrometry and Conventional Biochemical Tests
Identification of Actinomyces spp. by conventional phenotypic methods is notoriously difficult and unreliable. Recently, the application of chemotaxonomic and molecular methods has clarified the taxonomy of the group and has led to the recognition of several new species. A practical and discriminatory identification method is now needed for routine identific

6. Pyrolytic Methylation-Gas Chromatography of Whole Bacterial Cells for Rapid Profiling of Cellular Fatty Acids
A novel, on-line derivatization technique has been developed which enables generation of fatty acid methyl ester (FAME) profiles from microorganisms by gas chromatography-mass spectrometry without the need for laborious and time-consuming sample preparation. Microgram amounts of bacterial cells are directly applied to a thin ferromagnetic filament and covere

7. Characterization of Bacteria by Particle Beam Mass Spectrometry
A technique is described for detecting and characterizing bacteria on a single-particle basis by mass spectrometry. The method involves generation of a particle beam of single whole cells which are rapidly volatilized and ionized in vacuum in the ion source of a quadrupole mass spectrometer. The particle beam can be generated, with minimal sample handling, f
