A method of selection for type II methanotrophs is provided that includes enriching a microbial feedstock using a non-sterile bioreactor with a methane source and a nitrogen source, where the microbial feedstock includes a mixture of Type I and Type II methanotrophic cells, where an inhibited growth of the Type I methanotrophic cells and an enhanced growth of the Type II methanotrophic cells forms. The method further includes exposing intermittently the enriched microbial feedstock to i) nitrate, ii) urea, or i) and ii), where enhanced growth of the Type II methanotrophs is established, and exposing the Type II methanotrophs to an unbalanced growth condition where production of polyhydroxybutyrate is induced.

A membrane supported bioreactor arrangement and method for anaerobic conversion of gas into liquid products including membrane modules having hollow fibers packed across a cross sectional area of the membrane module, each of the hollow fibers formed from an asymmetric membrane wall having a porous outer layer defining biopores for retaining a porous biolayer about the outer surface of the membrane wall and a less permeable hydration layer around the hollow fiber lumen; a membrane vessel for surrounding the outside of the hollow fibers with a process gas from a gas supply conduit; and a liquid supply conduit operably connected to the hollow fibers for supplying a process liquid to the hollow fiber lumens. The gas supply conduit enables the formation of a biolayer on the outer surface of the hollow fiber wall by interaction of microorganisms with the process gas and the production of a liquid product.

Methods and systems for the production of hydrocarbon products, including providing a substrate comprising CO to a bioreactor containing a culture of one or more micro-organisms; and fermenting the culture in the bioreactor to produce one or more hydrocarbon products. The substrate comprising CO is derived from a CO2 reforming process.

A method for controlling electrical power consumption for a first group of functional which can be used for operational management during operation of the bioreactor components during operation comprises, inter alia, adjusting a present power control signal for one or more of the functional components from the first group in order to optimise power consumption, when a comparison shows for the first group of functional components that the currently required total electrical power consumption is greater than a predefined total electrical power consumption, such that, for the first group of functional components, an adjusted total electrical power consumption is not greater than the predefined total electrical power consumption. A biotechnological apparatus comprises a bioreactor, a reactor vessel formed in the bioreactor and having a cultivation chamber, and a temperature control device provided with a heat pump and configured to control the temperature of the cultivation chamber.

The invention provides an integrated bioreactor for adherent cell culture. The bioreactor comprises a regulation and control system, a reaction vessel body and a cell culture unit which are sequentially connected and internally communicated with one another; the regulation and control system is provided with a gas pressure balance hole and a liquid dropping hole, the cell culture unit is providedwith a central flow guiding hole and a liquid level monitoring hole, and the gas pressure balance hole and the liquid level monitoring hole are communicated with each other through a pipeline to forma liquid level sensor; the bioreactor further comprises a cell suspension bottle, one end of the central flow guiding hole is communicated with the liquid dropping hole through a pipeline, and the other end of the central flow guiding hole is communicated with the cell suspension bottle through a pipeline. The integrated bioreactor successfully exchanges and circulates culture mediums of the cellculture unit and the regulation and control system, and the unified regulation and control over the pH value and the dissolved oxygen value of each unit culture medium are successfully achieved; the laminar flow shear force and liquid level of the cell culture unit are also regulated and controlled.
