Abstract (en)
[origin: WO9731682A1] The invention relates to a process for microbial decomposition of harmful substances in media charged with harmful substances during cleaning of air, sewage and soil. It also relates to a device for performing said process, micro-organisms suitable for performing said process and the use thereof. The object of the invention is to improve said process in such a manner that micro-organism cultures used to break down harmful substances are established on a long-term basis, and at the same time to achieve high rates of decomposition. To attain said object, the invention proposes a process in which there is continuous decomposition fermentation in a decomposition fermenter using micro-organisms, available in the medium charged with harmful substances, and/ or a micro-organism culture added to the medium. During decomposition fermentation the concentration of harmful substances in the decomposition fermenter is controlled to make it toxin-static or toxin-dynamic using a control circuit, as a function of the vitality of the biomass. To decompose formaldehyde, the invention proposes the use of particular micro-organisms which decompose formaldehyde. To decompose phenols, the invention proposes the use of particular micro-organisms which decompose phenol.
