A portable culture test apparatus, comprising: a mounting portion on which a culture dish can be mounted; a vibrating portion that vibrates the mounting portion; a temperature adjusting mechanism that adjusts the temperature of the mounting portion; and an ultraviolet lamp that irradiates the culture dish mounted on the mounting portion with ultraviolet.

Acoustic perfusion devices for separating biological cells from other material in a fluid mixture are disclosed. The devices include an inlet port, an outlet port, and a collection port that are connected to an acoustic chamber. An ultrasonic transducer creates an acoustic standing wave in the acoustic chamber that permits a continuous flow of fluid to be recovered through the collection port while keeping the biological cells within the acoustic chamber to be returned to the bioreactor from which the fluid mixture is being drawn.

Ultrasonic devices comprise a housing comprising an ultrasonic surface, an ultrasonic transducer, and an ultrasonic horn to provide and focus energy from the ultrasonic transducer to the ultrasonic surface. Methods of removing trapped air bubbles from a cell culture container comprise positioning a cell culture container comprising air bubbles trapped in liquid within microcavity wells of the cell culture container at an ultrasonic surface of an ultrasonic device. Mechanical agitation is generated by the ultrasonic device and applied to the cell culture container to remove the trapped air bubbles from the microcavity wells. Methods of releasing cell aggregates from a cell culture container comprising positioning a cell culture container comprising cell aggregates in microcavity wells at an ultrasonic surface of an ultrasonic device. The cell aggregates are released from the microcavity wells by applying mechanical agitation from the ultrasonic device to a surface of the cell culture container.

Articles of manufacture, including an apparatus for acoustic wave based agglomeration, are provided. The apparatus may include a well and an acoustic wave device. The well may be configured to hold a suspension that includes a plurality of particles. The acoustic wave device may be configured to generate a plurality of acoustic waves. The plurality of acoustic waves inducing acoustic streaming within the suspension. The acoustic streaming agitating the suspension to form an agglomerate comprising at least a portion of the plurality of particles. Methods for acoustic wave based agglomeration are also provided.

This new application can be administered completely by artificial Intelligence or manually while utilizing the artificial intelligence platform enabling cost savings. This new artificial intelligence application is a breakthrough in that it is based on highly accurate data which leads to learned behaviors of micro-organisms. This data is applied to accurate management and elimination of threats from micro-organisms to people, plants and animals using biosurfactants. This new cost-efficient AI conveyor belt micro-organism application gets us closer to understanding what lurks around us.

The present invention provides a separator for microorganisms in cavitary contents. The separator for microorganisms in cavitary contents includes a raw material vessel, a stage filter, a liquid storage vessel, a closed separated material vessel, a separate loading unit, a deodorizer, pipelines for connecting all the units, etc.

An object of the present invention is to provide: an algae water concentration system that efficiently concentrates algae water in a culture pond into algae water containing algae having a desired size, with a simple structure and at low cost; and a method for operating the same. A cultured algae water concentration system 100 comprises: an algae water supply unit 17 that has an algae water supply container 18 that stores algae water sent from the culture pond therein, and a supply container outlet port 19 through which the algae water is taken out from the algae water supply container; and an algae water concentration unit that has a concentration container 1 for receiving and concentrating the algae water from the algae water supply unit, a filter 3 which divides the concentration container into upper and lower spaces and does not pass algae having a predetermined size or larger therethrough, a vibration device 5 that vibrates the filter in an out-of-plane direction, a concentration container algae water inlet port 7 which takes in the algae water to the concentration container and is arranged below the filter of the concentration container, a concentrated algae water outlet port 9 that is arranged below the filter of the concentration container and takes out algae water therethrough that has been concentrated in the concentration container, and a filtered water discharge port 8 that is arranged above the filter of the concentration container and discharges filtered water having passed through the filter.

Aspects of the disclosure are directed to an apparatus for separating a second fluid or a particulate from a host fluid. That apparatus comprises a flow chamber with at least one inlet and at least one outlet. A drive circuit configured to provide a drive signal to a filter circuit configured to receive the drive signal and provide a translated drive signal. An ultrasonic transducer is cooperatively arranged with the flow chamber, and transducer includes at least one piezoelectric element configured to be driven by the current drive signal to create an acoustic standing wave in the flow chamber. At least one reflector opposing the ultrasonic transducer to reflect acoustic energy.
