A culture device comprising: an adjusting gas supplier which supplies to a culture space an adjusting gas for adjusting the concentration of a definite gas component in the culture space; an adjuster which adjusts the moisture in the culture space; and a controller which controls the adjuster, wherein the controller controls the adjuster depending on the supply amount of the adjusting gas or a parameter correlated to the supply amount.

Techniques for predicting an amount of at least one biomaterial produced or consumed by a biological system in a bioreactor are provided. Process conditions and metabolite concentrations are measured for the biological system as a function of time. Metabolic rates for the biological system, including specific consumption rates of metabolites and specific production rates of metabolites are determined. The process conditions and the metabolic rates are provided to a hybrid system model configured to predict production of the biomaterial. The hybrid system model includes a kinetic growth model configured to estimate cell growth as a function of time and a metabolic condition model based on metabolite specific consumption or secretion rates and select process conditions, wherein the metabolic condition model is configured to classify the biological system into a metabolic state. An amount of the biomaterial based on the hybrid system model is predicted.

An apparatus is provided for producing methanol from organic material, characterized in that the apparatus includes

an anaerobic digestion arrangement for receiving the organic material and for anaerobically-digesting the organic material in oxygen-depleted conditions to generate methane gas; and
a chemical reaction arrangement for reacting the methane gas with water vapour and carbon dioxide in a stoichiometric condition (Eq. 4) between methane steam reforming and methane dry reforming to generate methanol.

The apparatus is operable to support a stoichiometric reaction as follows:

CO.sub.2+3CH.sub.4+2H.sub.2O=4CH.sub.3OH  Eq. 4

The chemical reaction arrangement is operable to provide the stoichiometric condition (Eq. 4)

at a first stage for steam reforming at a pressure in a range of 10 Bar to 30 Bar, and at a temperature in a range of 750° C. to 950° C.; and
at a second stage of methanol synthesis at a pressure in a range of 50 Bar to 100 Bar, and at a temperature in a range of 200° C. to 250° C.

Optionally, a catalyst arrangement is employed for at least the second stage.

Methods for controlling a biological manufacturing system include directing a light beam to pass through a wall of a vessel containing a first fluid generated by the biological manufacturing system, measuring an angle of refraction of the light beam in the first fluid, the angle of refraction corresponding to an angle between a propagation direction of the light beam in the first fluid and a normal to an interface between the vessel wall and the first fluid, determining information about the first fluid based on the measured angle of refraction, and adjusting a parameter of the biological manufacturing system based on the information about the first fluid.

The present disclosure provides cassettes for use in automated cell engineering systems that include cell concentration filters for reducing fluid volume of a cell sample during or following automated processing. The disclosure also provides methods of concentrating a cell population, as well as automated cell engineering systems that can utilize the cassettes and carry out the methods.

Combining through self-modulation a flow of active media from a working vessel of a bioprocess together with a flow of reference media and making a time- and/or spatially-resolved referenced optical measurement of the active vs reference media in a confined flow region and time, such that the two liquids are measured in substantially identical conditions.

A laboratory container, in particular a cell culture container, includes a container volume which is surrounded by a container body and which can be accessed from the outside through a container opening of the container body. The container has a fluid line which communicates with the container volume and which comprises a valve arrangement. The fluid line is designed to conduct fluid in order to discharge and/or introduce fluid out of and/or into the container volume. The fluid line can be selectively released in order to conduct a fluid or blocked by the valve arrangement, and the container additionally has a gas balancing opening, through which gas can be introduced into or discharged out of the container volume in counterflow to a possible fluid flow in the fluid line. The gas compensating opening is surrounded by a channel wall, said line channel running from the gas balancing opening into the container volume and opening into said container volume.
