A cup of coffee contains mutagens which produce about 5 X 10(4)-10(5) revertants of Salmonella typhimurium TA 100 without S9 mix. One of the mutagens was identified to be methylglyoxal. Methylglyoxal was present in various beverages such as black tea, whisky, and brandy. Methylglyoxal itself induced tumors in rats when administered by subcutaneous injection.

Respiratory symptoms and lung function were studied in nine coffee workers who complained of job related respiratory symptoms. Six described symptoms characteristic of occupational asthma. Lung function data showed obstructive changes mostly in the smaller airways with no impairment in diffusing capacity. Bronchoprovocation testing with green coffee allergen provoked immediate asthmatic reactio...

• Five different lignocellulosic biomass feedstocks were hydrothermally treated. Elevated hydrothermal conditions linked to structural changes. A novel method for quantifying the effects of treatment. Hydrothermal treatment has a higher impact on hemicellulose-cellulose structures. (Coffee residues, Rice waste, Whitewood, Zilkha black, and Lignin) processed in semi-continuous flow rig using 9 p...

Increasing energy demands around the globe require alternative sources of energy. Considering large amount agro-industrial and agriculture-related activities in Colombia, generation from biomass waste is a promising option to meet needs country. Anaerobic digestion (AD) good use these wastes. In this study, several potential substrates for biogas using AD systems were identified through literat...
