fermelnters or other processes for the treatment or conversion of organic substances, and also for improving viscosity, in which specifically required, technological or biological procedures are combined in one mixing and combi-hydrolysis tank. The device has one or more descending walls for separating the gas chamber in the top part of the tank, one descending wall of which separates the gas chamber of the tank opening from the other tank, and optionally a further descending wall, the lower end of which is permanently located above the lowest fluid level and which separates the gas chamber of the pump chamber from the other tank. The device optionally has an ultrasonic module for treating a recirculated material from an advanced fermentation stage or from the device according to claim 1, and also a gas supply system in the lower zones of the feed and/or pump chamber for hydrogenous gases, produced in the process or supplied externally, for stimulating methane formation by means of hydrogen-oxidising archaea.

A cell culture system is provided that includes a cell culture vessel enclosing an interior configured to culture cells in liquid cell culture media, the cell culture vessel comprising a bioreactor inlet for supply of cell culture media to the interior and a bioreactor outlet for removal of cell culture media from the interior; and a media conditioning system comprising an enclosure enclosing an interior space and a gas exchange system, the gas exchange system comprising a media vessel, wherein the media vessel comprises at least one media cavity configured to contain cell culture media and a gas permeable membrane separating the media cavity from the interior space.

The disclosure relates to bioreactors, for example for biological treatment and, more specifically to bioreactor insert apparatus including biofilms and related methods. The bioreactor insert apparatus provides a means for circulation of reaction medium within the bioreactor, a biofilm support, and biological treatment of an inlet feed to the reactor/insert apparatus. The bioreactor insert apparatus has a high relative surface area for biofilm attachment and is capable of generating complex flow patterns and increasing treatment efficiency/biological conversion activity in a biologically-active reactor. The high surface area structure incorporates multiple biofilm support structures such as meshes at inlet and outlet portions of the structure. The biofilm support structures and biofilms thereon can increase overall reaction rate of the bioreactor and/or perform some solid/liquid separation in the treatment of the wastewater or other influent.

Disclosed herein is a system and method for condensing moisture in a gas stream entering or leaving a bioreactor, the system comprising: a contact condenser container fluidically coupled to the bioreactor through an exhaust line; a condensate accumulator fluidically coupled to the contact condenser container through at least a first condensate line and a second condensate line; the condensate accumulator further fluidically coupled to the bioreactor through a condensate overflow line; a first condensate control device disposed on the first condensate line and configured to control a flow of condensate leaving the contact condenser container and entering the condensate accumulator; and a second condensate control device disposed on the second condensate line and configured to control a flow of condensate leaving the condensate accumulator to be mixed with the gas stream.

The invention relates to a device for hydrating with a liquid sample, the device comprising a container (4) for receiving at least one liquid sample, and a lid (5) possessing a bottom face (5.sub.1) having at least one hydrating support (3) fastened thereto to present an absorption face (3.sub.1) for absorbing a liquid sample. According to the invention, the container (4) presents, by means of at least one well (6), a calibrated volume for receiving a liquid sample, the at least said well presenting a hydrating calibrated open section for hydrating a hydrating support (3) defined by the top edge (8) of at least said well (6), the hydrating calibrated open section possessing an area that is less than the area of the absorption face of the hydrating support (3) in order to control the absorption by capillarity of the liquid sample by the hydrating support.
