Patent number: 4622303Abstract: Troublesome foaming in the fermentation of yeast is suppressed by the addition of polyglycol ethers which are derived from saturated and monounsaturated C.sub.16 -C.sub.18 fatty alcohols and which contain on an average of from 1 to 4 ethylene and/or propylene glycol ether groups. Preferred defoamers contain oleyl and cetyl alcohol residues in a ratio of from 3:1 to 1:1, and on average 2 ethylene glycol ether groups. The defoamers do not inhibit yeast growth or lead to premature softening and liquefaction of the compressed yeast.Type: GrantFiled: January 29, 1985Date of Patent: November 11, 1986Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Karl Schmid, Joachim Schindler, Adolf Asbeck

Patent number: 4618582Abstract: In the aerobic culture of microorganisms of the Xanthomonas genus in fermentation media, the use of water-in-oil emulsions in the media minimizes viscosity problems and enhances yields of Xanthomonas biopolymers. Preferably, the emulsion is formed with a surfactant and the microorganism is Xanthomonas campestris.Type: GrantFiled: February 8, 1982Date of Patent: October 21, 1986Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Konrad Engelskirchen, Werner Stein, Michael Bahn, Ludwig Schieferstein, Joachim Schindler, Rolf Schmid

Patent number: 4544965Abstract: To insure that a tape which is newly inserted into a reversing-type cassette tape transport mechanism will always operate in a first predetermined or priority direction, a direction priority switch (S3) is coupled to the tape cassette receiver (32, 34) to sense introduction of a tape into the receiver. The priority switch is coupled to a logic network which controls change-over of operation of a tape transport system (20, M) if the tape transport system, upon introduction of a tape, was operating counter the priority direction, but leaving unaffected the operation of the tape transport system if it was already in the priority direction. A suitable logic network comprises an AND-gate with a dynamic input, or one with a static input and a buffer memory which is reset upon termination of tape operation. If the tape is merely moved between a transducing position and a park or pause position, no change in direction of tape transport will result.Type: GrantFiled: April 29, 1983Date of Patent: October 1, 1985Assignee: Blaupunkt Werke GmbHInventors: Tilo Diepholz, Walter Hapke, Wilhelm Wohl, H.-Joachim Schindler

Patent number: 4473644Abstract: Process for the preparation of acid stable protease having a broad activity spectrum by culturing selected mutants of Rhizopus rhizopodiformis CBS 227.75 under aerobic conditions in a nutrient medium containing assimilable carbon and nitrogen sources, at a pH between 3 and 7 and at a temperature between 25.degree. C. and 50.degree. C., and separating the resulting protease enzyme; the mutants used in the process together with a process for preparation of the mutants.Type: GrantFiled: August 18, 1982Date of Patent: September 25, 1984Assignee: Henkel Kommanditgesesllschaft auf AktienInventors: Joachim Schindler, Friedhelm Bartnik, Rolf Schmid, Albrecht Weiss

Patent number: 4362815Abstract: For the production of 17-C-steroid-.alpha.-propionic acid compounds by microbial side chain degradation on 17-C-side chain steroid substrates wild strain microorganisms selected in predetermined manner are subjected to a multi-stage mutation and selection. The resultant mutant strains are capable of supplying the desired compounds, e.g. .DELTA.-4 BNC and/or .DELTA.-1,4 BNC in high yields even in the absence of inhibitors arresting the growth and/or degradation of the steroid ring. Wild strains and mutants particularly suitable, and their choice, production and use, are described.Type: GrantFiled: March 7, 1980Date of Patent: December 7, 1982Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Frank F.
