Abstract: There is disclosed a method of decomposing fermentation-inhibiting substances in a fluid including saccharide-containing substances, wherein a microbiotic mixture, especially a mixture of photosynthetically working micro-organisms and light-emitting micro-organisms is introduced into the fluid, the mixture being intended to decompose the fermentation-inhibiting substances.

Abstract: The invention relates to a bioreactor for the treatment of industrial or domestic effluent, comprising a container and a packing, wherein a potential difference forms between the packing and the container, which is provided with a device which prevents corrosion of the container as a result of the potential reversal due to the growth of a biofilm.

Abstract: A process for the purification of water is described, wherein a solution containing a proportion of a mixed microbiotic culture is added to the water in an environment having catalytic activity. This process may effectively be used for the purification of effluents and of waters in public and private installations.

Abstract: What is disclosed is a bioreactor comprising a strainer basket, inside which a filler body consisting of a porous carrier having a high specific surface area is received. Into this strainer basket a mixture of microorganisms is introduced which preferably includes a proportion of photosynthetically active microorganisms and a proportion of light-emitting microorganisms, so that a photodynamic decomposition of organic substances takes place. In accordance with the invention, the mixture of microorganisms contains a proportion of photocatalytically active nanoparticles.

Abstract: What is disclosed is a conditioning agent for the treatment of effluent and a process for preparing such a conditioning agent which includes a proportion of flocculating or precipitating agent containing polymers as well as a proportion of micro-organisms.

Abstract: A microbiological energy source for driving an electrical or mechanical consumer is disclosed, wherein at least one filling body having a piezoelectric or similar effect is received in a bioreactor. This bioreactor encloses waste water flowing through it, and contains a mixture of micro-organisms that form a positive pole and a negative pole of the energy source as a result of the microbiological decomposition of organic matter contained in the waste water.
