Sensory Evaluation Analysis of the spirits showed globally similar profiles at low retention times (between 0 and 10s) for the main volatile compounds (Fig. 3). The chromatographic profile could be represented as an odour map using a Principal Component Analysis (PCA, Fig. 4). The various samples are represented according to their relative volatile contents on a 2-axis graph with PC1 explaining...

The catalytic activation of CO single crystal surfaces is reviewed. Examples are provided which demonstrate the relevance of single crystal studies for modeling the behavior of high surface area supported catalysts. The coupling of an apparatus for the measurement of reaction kinetics at elevated pressures with an ultrahigh vacuum system for surface analysis allows detailed study of structure s...

The paper is a review of some current practices in the treatment and disposal of the more important fermentation industry effluents. Reference is made to the production of whisky and other potable spirits, malt, beer, vinegar, yeast, cider, antibiotics and vitamins. The most important means of treating distillery effluents is by recovering the soluble and some insoluble material in the liquid r...

An efficient microbial technique for decolorizing distillery wastewater was achieved using irradiated spores of Aspergillus fumigatus. The fungus was isolated from soil samples taken from the local distillery processing unit. By using the irradiated spores, wastewater decolorization increased by 14.3% as compared to that of the control treatment (68.8% vs. 54.5%). In the presence of sodium nitr...

A bacterial strain was isolated from tannery effluent which can tolerate high concentrations of potassium dichromate up to 1000 ppm. The isolated microorganism was identified as Pseudomonas aeruginosa by performing biochemical tests and molecular characterization. In the presence of excess of carbohydrate source, which is a physiological stress, this strain produces Polyhydroxybutyrate (PHB). T...

Pseudomonas aeruginosa and Vibrio cholerae showed a strong positive chemotactic response towards rum distillery wastewaters (mostos) and a high oxygen uptake rate in the presence of this complex substrate. Rum slops stimulated only motility in Aeromonas hydrophila and Escherichia coli. The A. hydrophila and E. coli isolates were unable to oxidize mostos significantly.
