Comment on :408044 Subject: Book Review Thank you, Foo for the information. Here is my self introductory message: I am Siegfried Michael Schoberth, and I am working in the Institute of Biotechnology-1 (IBT-1) at the KFA-Juelich (Nuclear Research Center Juelich), FRG, thus one of the about 4500 employees of the KFA. I am Wissenschaftlicher Mitarbeiter (Research Associate), but also involved in teaching. Years ago, me and my family had very nice 1.5 years in Urbana/Illinois/USA, for me to learn work with methanogenic bacteria in R. Wolfe's lab at the Department of Microbiology/University of Illinois, and for my family (and me too) to enjoy the American way of life; yet recently we detected the good Australian way of life during a research study in S ydney. Since my Ph.D. work I study the microbiology of anaerobic bacteria, especially those found in methanogenic communities. A recent publication is: Folkerts, M., U. Ney, H. Kneifel, E. Stackebrandt, E.G. Witte, H. Foerstel, S.M. Schoberth, and H. Sahm. 1989. Desulfovibrio furfuralis sp. nov., a Furfural Degrading Strictly Anaerobic Bacterium. System. Appl. Microbiol. 12, 161-169. D. furfuralis is able to degrade furfural anaerobically (furfural is found in bulk quantities in sulfite evaporator condensate (SEC) from many pulp and paper industries). The special technique to isolate this organism and its use in anaerobic treatment of SEC has been patented. KWU (SIEMENS) and SCHOTT Mainz build anaerobic treatment plants in collaboration with us and IBT-2. There is also an IBT-3 at the KFA.

What would be a good EARN etc. address for sending annoying tryout messages to? Regards, Siggi Sender: Siegfried Michael Schoberth Comment on :403963 Subject: AAFFE-process Mr. Iza: In front of me is a copy of M.S. Switzenbaum, et al. August 1978. The Anerobic A t tached Film Expanded Bed Reactor for the Treatment of Dilute Organic Wastes. US D epartment of Commerce, National Technical Information Service. I would be intere s ted what happened to AAFFE, since I lost touch to some applied aspects of anaero b ic treatment. Thanks, Siegfried M. Schoberth

Sender: Siegfried Michael Schoberth Subject: Jamaica Connection This is more a "Cocktail"- than an A.D.- question: Does anyone happen to know an address which could be contacted in Jamaica, if ne c essary, by two two youngsters (aged 19, fond of Bob Marley and Reggae), just rel e ased from high school, and eager to travel the US and Jamaica during July this y e ar. One of the explorers is my son. Of course, if this address happens to be an a naerobic digestion site, I would be the more glad to learn about it. Some years a go, I had contact with Bacardi Rum about their anaerobic filter in Puerto Rico ( t hen the biggest anaerobic filter in the world, 3.5 million gallon i.e. 13249 cub i c m). Maybe in Jamaica a similar site exists? Regards, Siegfried M. Schoberth

Subject: New Publications *Receiver: Anaerobic Digestion (MIRCEN) Technical* ------------------------------------------------------------ A.J.L. Macario, E. Conway de Macario, U. Ney, S.M. Schoberth, and H. Sahm. 1989. Shifts in Methanogenic Subpopulations Measured with Antibody Probes in a Fixed-Bed Loop Anaerobic Bioreactor Treating Sulfite Evaporator Condensate. Appl. Environm. Microbiol. 55(8):1996-2001. From the Abstract: *** A fixed-bed loop, high rate anaerobic bioreactor traeting sulfite evaporator condensate was sampled when it reached steady state and afterwards following perturbations during a 14-month period. By using immunotechnology, it was observed that shifts in methanogenic subpopulations occurred in association with perturbations, such as restarting and relocating the biomass into a different tank. *** Since some years, the Macarios (Albany, NY state) do a very fine work on the immunology of methanogens. They can name you many a strain within short time, only by obtaining a small sample of mud. Siegfried M Schoberth ------------------------------------------------------------
