The invention provides a system for observation of media dissolution and/or bacterial growth in a transparent bag, comprising a receptacle for supporting the bag, and a light emitting device arranged to transmit light into and/or through the interior of the bag supported at the receptacle. The media in the transparent bag can be visually inspected to confirm the dissolution state of the media and check for residual undissolved media and/or confirm the absence of unexpected microbial growth without having to move or handle the bag as it can remain supported in a defined orientation at the receptacle during repeated visual inspections by means of the light emitted from the light emitting device

A device and method for protecting cells, gametes, embryos, and oocytes from the harmful effect of illumination. The device is a culture dish that is optimized to create a dark environment inside of the dish. The culture dish features a base, an exterior wall connected to the outer rim of the base that forms an enclosure, and a lid connected to the exterior wall. The dish is preferably made of polystyrene and lid is preferably made of aluminum foil.

The method features the following steps: reducing a room exposure to sunlight, where the cells and embryos are located; covering the room ceiling lighting with color filter-luminaires; shielding the transparent surfaces of the applied aspiration set and test tube from light; applying a colored red-light filter to the IVF workstation; and incubate cells and embryos in a light-protected place.

A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a condition of the algal cells and/or a condition of an algal cell culture provided by cultivating the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured condition of the algal cells and/or the measured condition of the algal cell culture.

The invention relates to a bioreactor comprising a tank containing a culture medium in which a cell culture composed of algae cells is dispersed. The cell culture of algae has a concentration greater than 0.1 g/L in the culture medium, and each algal cell has a minimum absorption in a specific range of wavelengths of light. The bioreactor comprises a light source that is capable of emitting incident light in the direction of the tank, 60% of the photons of the incident light having a wavelength which is included in said specific range of wavelengths of light. The invention also relates to the use of the bioreactor for the production of biomass.
