5543309 CARRIER CONTAINING E N Z Y M E S FOR TREATING S E W A G E SLUDGE Pischel Emi Belfair, WA, UNITED STATES A carrier is prepared containing bacteria and/or enzymes for degrading sewage sludge. The carder can be in the form of a gel containing coloring matter and optionally a deodorant, or in the form of a core for a roll of toilet tissue or a roll of towels. In a preferred embodiment, the carder is in the form of a tube that is used as a core for a roll of toilet tissue. The tube is formed from at least two layers made from cellulose bonded together with a water soluble bonding agent. Enzymes and/or bacteria can be in a slurry of cellulose pulp used to make the core, in the bonding agent, or in a coating or strip on an inside and/or outside layer. The tube contains a plurality of sets of circumferential perforations that enable, after removing toilet tissue, readily breaking the tube into a plurality of small pieces that can be flushed down a toilet bowl into a sewage system where the pieces disintegrate and release the enzymes and/or bacteria. The tube may also contain a plurality of holes that allow an aqueous medium to readily seep between the layers to assist in disintegration.
5543317 MICROBIAL DEGRADATION OF T R I C H L O R O E T H Y L E N E D I C H L O R O E T H Y L E N E S AND A R O M A T I C POLLUTANTS Shields Malcolm S; Francesconi Stephen C Gulf Breeze, FL, UNITED STATES A novel bacterium named Pseudomonas cepacia PRI23 (formerly designated G4 5223 PR1) has the desirable property of constitutively degrading hazardous chemicals, for example trichloroethylene, 1,1-dichloruethylene,cis- 1,2 dichloruethylene, trans- 1,2-dichloroethylene, toluene, phenol, o-cresol, m-cresol, o-xylene, and benzene, to harmless chemical entities. This microbe, and mutants thereof which retain the constitutive degradation property of the parent, can be used in bioreactor and in situ processes for degrading hazardous chemical compounds. The
nucleic acid sequences which encode the degradative peptides have also been isolated and sequenced. Cells transformed with the isolated nucleic acid also produce the peptides comprising the enzyme which can constitutively degrade these hazardous chemicals. The enzyme can be isolated from such microorganisms (those which naturally harbor the gene or those which are transformed with the gene) and applied to a sample having the hazardous chemical(s) or contaminant(s) in order to degrade the contaminant(s).
5545559 COMPOST MAKER Kariniemi Pekka Kauttua, FINLAND Assigned to Favorit Oy PCT No. PCT/FI93/00053 Sec. 371 Date Aug. 11, 1994 Sec. 102(e) Date Aug. I 1, 1994 PCT Filed Feb. 17, 1993 PCT Pub. No. WO93/16018 PCT Pub. Date Aug. 19, 1993. A compost maker comprising an upright container having on its top end a cover for introducing material to be composted in the container, having in its lower part a hatch for removing composted material from the container, and containing an air tube system for guiding air in among the material to be composted. The air tube system comprises at least two tubes on different heights, the lower tube being connected through the wall of the container with an air intake aperture, and which are interconnected with a connecting tube and their lower parts provided with holes. The cover is fitted with an exit duct, the air flowing through the holes in the tubes and upward through the material to be composted and through the exit duct out from the container. The material to be composted, supported by the transverse tubes, moves in controlled manner downwardly as the composting of the material progresses.
