  • Patent number: 9139588
    Abstract: The presently disclosed subject matter demonstrates that ThnG and ThnQ enzymes encoded by the thienamycin gene cluster in Streptomyces cattleya oxidize the C-2 and C-6 moieties of carbapenems, respectively. ThnQ stereospecifically hydroxylates PS-5 giving N-acetyl thienamycin. ThnG catalyzes sequential desaturation and sulfoxidation of PS-5, giving PS-7 and its sulfoxide. The ThnG and ThnQ enzymes are relatively substrate selective, but give rise to the oxidative diversity of carbapenems produced by S. cattleya, and orthologues likely function similarly in allied streptomyces.

  • Patent number: 8496839
    Abstract: A filter device including at least one filter chamber between a filter plate and a counter plate when the device is closed, into which chamber a suspension can be inducted on a cake side of a filter cloth through at least one filling shoe anchored in the filter plate and clamping the cloth with the filter plate in a sealing manner. The suspension permeates the cloth to the filtrate side, wherein the suspension solid content deposits on the cloth as a filter cake, and the filter and counter plates are offset from each other when the device is open, and the cake is removable from the chamber. In order to simplify the disassembly of the cloth, the shoe is movably anchored in the filter plate, and the shoe is automatically lifted off from the filter plate and the clamping of the filter cloth is released when the device is opened.

    Abstract: A filtering device, in particular for fish basins, has a housing (10) encompassing a filter chamber (20) and a filter drum (30), which is rotatably disposed in the filter chamber (20) and is loadable with water to be purified, about which a filter belt (40) is guided along part of its circumference from a dispensing roller (42) to a receiving roller (41) that is driven by a paddle wheel (5) disposed outside the filter chamber (20). The paddles (51) of the filter wheel are activated by unpurified water in such a way that the filter belt (40) is wound from the dispensing roller (42) onto the receiving roller (41). As the filter belt that loops around the filter drum becomes increasingly dirty and the water level in the filter chamber rises as a result, the unpurified water that is delivered by a pump flows over an overflow onto the paddle wheel as a mechanical drive means and places a receiving roller for the dirty filter belt into rotation.

  • Patent number: 7172699
    Abstract: In a wastewater treatment plant, the liquid side of the plant has preferably four stages for nitrification and/or denitrification, prior to further treatment such as a clarifier. Energy requirements are reduced by reducing aeration requirements. Four or more tanks/zones comprise serial anoxic and aerobic stages, but in the anoxic stages simultaneous nitrification/denitrification takes place in accordance with the known process of U.S. Pat. No. 5,906,746. By this arrangement the system can achieve a volume ratio of about 20% aerobic tankage to the total tankage volume, as compared to a much higher ratio in a typical prior art system of serial aerobic/anoxic stages, and greatly reducing aeration requirements.
