CO.sub.2, and other gases are utilized with mineral feedstock to synthesize products. The synthesized products, as the result of liquid, solid, gas photo-chemical reactions within the advanced bioreactor of the disclosed embodiment, are precipitated raw material for multiple consumer and industrial products. Waste heat, pressure and torque produced from the bioreactor are utilized for generating electricity and/or heat through a combination of energy recovery devices. Energy recovery devices offsets and lower the cost of operating the reactor as the disclosed reactor integrates photolysis via ultra-violet light, as an integral component, of a reactor system, composed also of an active mixer-agitator assembly, pressure and vacuum vessel chamber, heat source, and ports for media ingestion. The disclosed reactor is designed be conducive to transforming gaseous, solid, and liquid feedstock, like carbon dioxide —CO.sub.2, and other feedstocks that are inorganic and/or organic in an aqueous medium, into inorganic and organic products.

The present invention is in the field of a method of producing lactic acid in high yield in a sequencing batch reactor. Therein glucose may be used as feedstock for bacteria, which ferment the glucose into lactic acid. The reactor is operated under at least partly defined non-axenic conditions and in a cyclic mode.

A fully integrated and disposable point-of-care device for detecting a target nucleic acid is provided. The device comprises: an extraction chamber adapted to receive a biological sample, wherein said extraction chamber comprises means to extract and lyse the sample to release nucleic acid; a first amplification chamber in communication with the extraction chamber, wherein said amplification chamber comprises means to trigger nucleic acid amplification of a target nucleic acid sequence to occur; and a detection chamber in communication with the amplification chamber, wherein said detection chamber comprises means to detectably label the target nucleic acid and means to detect a signal associated with labeled target nucleic acid, or a single chamber for amplification, detection and identification of multiple nucleic acid sequences.

This disclosure relates to reaction container systems providing for headspace-based condensation, coalescing devices, and other features. In some embodiments, this disclosure provides systems that reduce the relative humidity (RH) of an exhaust gas prior to or concurrent with its expulsion from the system through an exhaust filter.

Incubators including an enclosure with an internal chamber configured to support a cell culture plate comprising a plurality of wells are disclosed. The enclosure includes a plurality of openings configured to allow access to the wells. The incubators include a sealing element configured to seal the plurality of openings in the enclosure. The sealing element comprises a plurality of openings corresponding to at least a subset of the plurality of openings in the enclosure. Access to the internal chamber can be provided by aligning the plurality of openings in the sealing element with the plurality of openings in the enclosure. Methods for using the incubators are also provided.

There is provided a method of controlling operation of a fed batch process in a bioreactor vessel, comprising transitioning from a batch phase to a production phase in dependence on a relationship between an oxygen supply parameter O and a dissolved oxygen value DO.

An anaerobic digestion device based on self-sustained air flotation includes an anaerobic digestion tank unit, a self-sustained air flotation screening unit and a biogas measurement and collection unit. The self-sustained air flotation screening unit includes an air flotation screening part, a material sedimentation part, a reflux part and a three-phase separation part connected sequentially from bottom to top. A digested material in the anaerobic digestion tank unit is pumped into the air flotation screening part, overflows into the material sedimentation part, and then is raised to the reflux part. Gas passing through the three-phase separation part and gas produced in the anaerobic digestion tank unit enter the biogas measurement and collection unit to be measured and collected.

A dynamic incubator system and method for mammalian cells. The dynamic incubator system includes an incubator and a programming device communicatively coupled to the incubator. The programming device includes a memory, one or more processors, a display, and an input mechanism. The programming device is adapted to enable at least one preset temperature and gas concentration sequence to be one or more of designed for the interior of the incubator, saved to the memory of the programming device and/or selected for implementation within the interior of the incubator. The at least one temperature and gas concentration sequence includes programmed changes to the temperature and a CO.sub.2 gas concentration. A purging mechanism is coupled to the incubator and releases a portion of a gas concentration to enable rapid changes in the temperature and gas concentration in the incubator.
