  • Patent number: 5700686
    Abstract: During the enzymatic "stone washing" of a denim fabric and/or garments, an undesirable redeposition of blue dye often occurs on the surfaces of the denim. The invention relates to a means of overcoming this problem using an enzyme composition comprised of Trichoderma endoglucanase and Trichoderma cellobiohydrolase that has been partially digested by a protease enzyme to separate its core and binding domains. The use of this composition reduces the redeposition of the blue dye and hence improves the stone washing process relative to using a redepositing or backstaining cellulase.

  • Patent number: 5656490
    Abstract: A method is presented for releasing petroleum and hydrocarbon products sorbed onto or entrained by organic natural fibers in an aqueous medium through the use of enzymes to degrade the organic natural fiber sorbents utilized for oil spill cleanup, the method provides an opportunity for achieving responsible separation of oil from oil spill sorbent materials. Natural organic fibers which have been utilized to adsorb petroleum and hydrocarbon products are separated from these petroleum and hydrocarbon products by reducing the natural organic fiber links to the point that the adsorbed or entrained oil no longer has sufficient binding surface or fiber link to remain held by the fibers, thus floats to the surface of the aqueous medium. Aqueous medium enzyme compositions are provided which are suitable for degrading organic natural fibers inclusive of cellulose-based and protein-based fibers resulting in release of adsorbed, absorbed and/or entrained petroleum products.

  • Patent number: 5466601
    Abstract: The present invention comprises a three step process that selectively removes embedded cellulose lint precursors from a cotton fabric with a cellulase solution during a continuous fabric manufacturing process. The cellulase solution, applied continually, travels in a finite, limited path and digests fibrils, forming embedded lint precursors, from the fabric. Undigestable fibrils, located outside the path travelled by the cellulase, remain undamaged by the cellulase. After the fabric's first wash, no appreciable linting is observed on the surface thereof and the fabric retains at least about 90% of its strength. Further, the process produces fabrics which do not exhibit commercially unacceptable yellowing from the action of the cellulase upon the cellulose.

  • Patent number: 5091089
    Abstract: Present invention offers, for the first time, a biological approach through the use of white-rot fungi to the decolorization of dye wastewater. It is also applicable to other colored substances and/or their wastewater such as molasses. Because of its low cost, renewable and regenerative activity, and little or no secondary pollution hazard, biological method is the most widely practiced method in nature and in practice in treating organic refuse and industrial waste. Current invention discloses, specifically, undiscovered activities of the Myrothecium and Ganoderma fungi in removing colored substances from dye solutions and dye wastewater. It is the result of a deliberate process of screening for natural water/soil-born and farm/industrial-waste-derived microorganisms for such specific purpose in our laboratory.The accompanied process invention shows that simple biological treatment could also produce consistently effective results in treating a wide spectrum of dye wastewater under greatly varied conditions.

  • Patent number: 4963491
    Abstract: Enzymes isolated from krill of the order Euphausiaceae are used to remove biological contaminants. Preferably, a mixture of enzymes including exo-and endopeptidase is isolated. The enzymes can be used in laundering or to clean or debride living tissue. Isolation may be carried out by homogenizing krill and extracting the enzymes with an aqueous medium. The enzymes may be further purified by gel chromatography. After lipids have been removed, the enzymes can be lyophilized for long time storage.

  • Patent number: 4912056
    Abstract: Denim having a stone washed appearance is produced without stones by treating with a cellulase enzyme. Unsewn dyed denim fabric or a newly manufactured garment made of dyed denim fabric is contacted with an aqueous composition containing at least about 2500 CMCS units of cellulase per liter, and subjected to mechanical action. Preferably, the aqueous composition provides at least about 6000 CMC units of cellulase per pound of unsewn fabric or garment. The aqueous may also contain an electrolyte, a buffer, a builder salt a cellulase activator, an antioxidant and a solubilizer.

  • Patent number: 4873016
    Abstract: The invention relates to a detergent composition comprising lipases. By inclusion of a certain, immunologically defined class of lipases in a detergent composition which comprises a mixture of an anionic and a nonionic detergent, an improved overall detergency is obtained. Typical suitable lipases are obtained from certain Pseudomonas and Chromobacter strains.

  • Patent number: 4865983
    Abstract: Cleaning compositions containing an extracellular protease produced by a microorganism of the genus Vibrio are provided. Such enzymes are characterized by a high proteolytic activity, stability over wide pH and tmperature ranges and excellent stability to oxidizing agents, including a unique stability to chlorine bleaches, and are well-suited for formulation into laundry detergents, automatic dishwasher detergents, laundry bleaches, pre-soaks, as well as other types of cleaning compositions.

  • Patent number: 4861509
    Abstract: The invention relates to the use of a certain class of lipases together with strong bleaching agents in detergent compositions. This class of lipases consists of fungal lipases ex Humicola lanuginosa or Thermomyces lanuginosus, and bacterial lipases which show a positive immunological cross-reaction with the antibody of the lipase produced by Chromobacter viscosum var. lipolyticum NRRL B-3673. The strong bleaching agents are stronger than the sodium perborate/TAED system, i.e. stronger than peracetic acid or they yield, on perhydrolysis, a peracid faster than the sodium perborate/TAED system.

  • Patent number: 4832864
    Abstract: Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.
