Patent number: 6017866Abstract: The present invention provides mutant lipases which retain lipase activity, but have improved surfactant resistance and are thus highly advantageous for use in detergent compositions. Preferred lipases of this type include modified functional forms of a lipase of Pseudomonas alcaligenes having one or more amino acid substitutions at or near the surface of the lipase which effect interaction of the hydrophobic portions of surfactant molecules with initiation sites on the enzyme for surfactant denaturation.Type: GrantFiled: October 22, 1996Date of Patent: January 25, 2000Assignee: Genencor International, Inc.Inventors: Wolfgang Aehle, Gijsbert Gerritse, Hermanus B.

Patent number: 6017746Abstract: A process for remedying an environment contaminated with an aliphatic organochlorine compound which includes the use of Pseudomonas cepacia strain KK01 (FERM BP-4235) or Corynebacterium species (FERM BP 5102) and Renobacter species (FERM BP-5353). The first two microorganisms are capable of introducing an oxygen atom into the aliphatic organochlorine compound in order to convert the aliphatic compound to an epoxide. During protonization the epoxide is converted into a chlorinated organic acid. Renobacter species strain FERM BP-5353 decomposes chlorinated organic acids to substances naturally existing in nature. The chlorinated and/or halogenated acids include chloroacetic acid, dichloroacetic acid, trichloroacetic acid and dichloropropionic acid, etc. The polluted environments in which the processes may be carried out include the soil, ground water and waste water.Type: GrantFiled: June 4, 1997Date of Patent: January 25, 2000Assignee: Canon Kabushiki KaishaInventors: Takeshi Imamura, Tetsuya Yano

Patent number: 5985268Abstract: A bacterial preparation from Pseudomonas species isolated #15 ATCC 55638 that has been exposed to gamma radiation exhibits cytotoxicity that is specific for neoplastic carcinoma cells. A method for obtaining a bacterial preparation having antitumor activity consists of suspending a bacterial isolate in media and exposing the suspension to gamma radiation. A bacterial preparation of an aged culture of an amoeba-associated bacteria exhibits anti-reverse transcriptase activity. A method for obtaining a bacterial preparation having anti-reverse transcriptase activity from an amoeba-associated bacterial isolate grown to stationary phase is disclosed.Type: GrantFiled: September 15, 1997Date of Patent: November 16, 1999Assignee: Lockheed Martin Energy Research Corp.Inventors: Arpad A.
