Microbes eat rocket propellant waste

Article Abstract:

Applied Research Assoc (ARA) plans to use the microbe Wolinella succinogenes in the remediation of groundwater contaminated with ammonium perchlorate wastes from a Kerr-McGee Chemical rocket-propellant plant in Henderson, NV. W succinogenes is a microaerophilic organism that degrades perchlorate to chloride. It is building a facility that will treat 825 gallons daily of groundwater with 300 to 500 ppm perchlorate. ARA says that after optimizing the process, it will only cost less than 20 cents per pound to remove the perchlorates.

Pectin process

Article Abstract:

The Eastern Regional Research Center of the US Dept of Agriculture has developed a microwave process for extracting pectin from citrus peel within 10 minutes' time. The experimental method can lead to huge energy savings since the procedure normally takes one hour using industrial heating techniques. The process produces pectin with molecular weight and viscosity similar to commercial pectin when used with orange peel at 80 degrees C and 23 psi.
