The present application belongs to the technical field of biology. Provided is a photobioreactor used for algae cultivation, said photobioreactor comprising: a reactor main body, a separation unit, and a first aeration device. The reactor main body is a sealed irregular tubular shape, the separation unit is located within the reactor main body, and divides the reactor main body into two spaces, a left space and a right space, and the first aeration device is connected to a bottom portion of the reactor main body. Also provided is an algae cultivation system, comprising the photobioreactor, the second aeration device, and a temperature control system, and being capable of regulating the temperature of an algae solution.

The present disclosure is generally directed to methods and devices for the precise and simultaneous optical irradiation and oscillating magnetic field radiation of a target, such as mammalian cells and/or nanostructures.

A cell monitoring plate comprises a flat surface on which multiple cell culturing vessels may be stacked. The flats surface has multiple optical imaging systems embedded therein to fully image a cell culture vessels stacked on the plate. Each one of the multiple optical imaging systems provides both illumination and imaging through a single aperture in the surface of the monitoring plate.

Disclosed is an internally illuminated bioreactor, and related algae production methods, that employ integrated in-water grow light assemblies configured to manage the heat generated by lighting elements, such as light emitting diodes (“LEDs”) on the in-water grow lights. The bioreactor includes an outer shell and one or more in-water grow light fixtures positioned within the outer shell that are positioned around the perimeter of a hollow, internal tube. The lighting elements and internal tube are themselves contained within a preferably clear, exterior tube of the light fixture that allows light generated by the lighting elements to pass through to the algae culture inside of the growth chamber. A heat management system is provided for cooling the light fixture using forced directed through the hollow, internal tube from the top to the bottom of the tube, out from outlets at the bottom of the internal tube, and upward in the fixture through buoyancy of the warmed air, and thus without additional mechanical air handling devices. As the air moves upward between the lighting elements and the exterior tube, it draws additional heat away from the lighting elements. The warmed air is ultimately exhausted from the top of the lighting fixture. Each lighting fixture preferably also includes a cleaning system that enables the automated cleaning of the outer surface of the exterior tube of the lighting fixture, thus preventing newly formed algae from collecting on the lighting fixture and ensuring a continuous flow of light from the fixture into the algae culture throughout algae production.

There is provided a cell detaching apparatus for detaching cells from a base material by applying an ultrasonic vibration via an acoustic matching liquid, with reduced variations of the vibration transmitted to the cells during application of the ultrasonic vibration. A cell detaching apparatus for detaching cells placed on a base material floating on an acoustic matching liquid, from the base material includes a holding unit configured to hold the acoustic matching liquid, a detaching unit configured to detach the cells from the base material by applying an ultrasonic vibration to the cells through the acoustic matching liquid, and a control unit configured to perform control to maintain a constant height of a fluid level of the acoustic matching liquid held by the holding unit with respect to the base material.

An alga growing apparatus that includes a gas dissolving portion, an alga tank, first and second LEDs, a supplying portion, and a circulation pump portion. Gas dissolving portion dissolves carbon dioxide and oxygen into deep-ocean water to form growing water. The circulation pump portion sucks out and delivers the growing water and the nori thalli from the alga tank 30 to the gas dissolving portion and injects the growing water and the nori thalli into the alga tank upon passage through the gas dissolving portion and a supply pipe of the supplying portion. The supplying portion discharges the growing water and the nori thalli along a direction obliquely intersecting a curving direction of an inner side surface of the alga tank and the growing water flows inside the alga tank as an eddy flow.

The invention relates to a device (10) for producing microalgae, comprising a basin (12) containing an aqueous medium and a movable support (14) capable of receiving a cell culture made up of algae cells, which movable support is immersed at least partially in the aqueous medium and has at least a first portion and a second portion, characterised in that the movable support is arranged in the basin such that the first portion is exposed directly to a main light source (18) and forms an exposure section (24), and the second portion is not exposed directly to the main light source (18) and forms an inhibition section (26), the device (10) further comprising a secondary light source (28) designed to emit actinic light in the direction of the inhibition section (26) so as to inhibit the pigment synthesis of at least some of the algae cells. The invention also concerns a method for producing microalagae.
