Coal liquefaction technology has been developed to the stagewhere successful pilot plants are now in operation in the united states. however, economic and environmental concerns have curtailed plans for commercial ventures. by solubilizing oxidized coal with the help of… More

Enzymes of interest in chemical/biological defense, particulaly oxidases and peroxidases, would be more useful if they could withstand high temperatures and had a longer shelf life. thermally labile forms now available could be synthetically stabilized but this would be expensive. microorganisms… More

The u.s. possesses huge coal reserves, but sulfur dioxide (so2) released upon combustion is a major contributor to acid rain. significant advances have been made in the development of microbial processes for precombustion removalof inorganic sulfur from coal. thiobacillus and sulfolobus sp. have… More

1Certain microorganisms are capable of degrading polyurethane coatings. This feat is accomplished by enzymes normally produced by these microorganisms. But microbial paint stripping, an environmentally compatible alternative to chemical and physical paint stripping, is unacceptably slow. The rate of… More

Enzymes used as the label for most non-radioactive assays and in biosensors, are the most unstable component of these systems. As immunoassays and biosensors move from the tightly controlled laboratory environment to demanding field conditions, the need for a more stable enzyme becomes critical.… More
