Use of yeast biocapsules as a fungal-based immobilized cell technology for Indian Pale Ale-type beer brewing.

Immobilized cell technologies (ICT) have been used in wort fermentation, beer maturation, or production of alcohol-free or low-alcohol beer. The purpose of ICT is to restrict intact cells to a specific location while allowing biological function. It improves cell stability, operational flexibility, and control in brewing, as well as ease in executing continuous operations.

Pseudomonas fluorescens PICF7 displays an endophytic lifestyle in cultivated cereals and enhances yield in barley.

Pseudomonas fluorescens PICF7, an indigenous inhabitant of olive roots, displays an endophytic lifestyle in this woody crop and exerts biocontrol against the fungal phytopathogen Verticillium dahliae Here we report microscopy evidence that the strain PICF7 is also able to colonize and persist on or in wheat and barley root tissues. Root colonization of both cereal species followed a similar pattern to that previously reported in olive, including inner colonization of the root hairs. This demonstrates that strain PICF7 can colonize root systems of distant botanical species.

Biofuel-Promoted Polychlorinated Dibenzodioxin/furan Formation in an Iron-Catalyzed Diesel Particle Filter.

Iron-catalyzed diesel particle filters (DPFs) are widely used for particle abatement. Active catalyst particles, so-called fuel-borne catalysts (FBCs), are formed in situ, in the engine, when combusting precursors, which were premixed with the fuel. The obtained iron oxide particles catalyze soot oxidation in filters.

Pollutant formation and emissions from cement kiln stack using a solid recovered fuel from municipal solid waste.

The thermal decomposition of a solid recovered fuel (SRF) has been studied by two techniques. First, laboratory-scale experiments were performed in a horizontal furnace in which different atmospheres were studied to analyze the dioxins and furans (PCDD/Fs) evolved from the decomposition of the material. Sulfur presence was revealed to be important in PCDD/Fs formation.

Analysis of dioxin-like compounds formed in the combustion of tomato plant.

In an initial effort to minimize some of the uncertainty regarding the open burning of biomass, emission factors of carbon oxides, light hydrocarbons, PAHs, PCDD/Fs and dioxin-like PCBs were determined in the combustion of tomato plant in a residential stove and in two runs at 500 degrees C and 850 degrees C in a laboratory scale reactor. In all the runs nearly the same PAHs were identified, being naphthalene the main obtained. Combustion of tomato plant at 500 degrees C in the laboratory scale reactor produced the highest emission factors for all compounds analyzed.
