In the production method, the peristaltic pump is operated, and the first liquid and the second liquid are mixed by circulating them to form the object liquid medium composition in the container.

A method of reconstituting a powdered cell culture media includes providing a mixing apparatus and providing a powdered cell culture media to the fluid chamber of the mixing apparatus, prior to introducing fluid to the chamber. The method further includes introducing fluid to the chamber through an influent port, wherein the influent port is tangentially oriented relative to an inner wall of the fluid chamber to thereby cause the fluid to follow the wall of the fluid chamber in a circular motion, creating a vortex flow in the fluid chamber by introducing fluid at a sufficient flow rate, and enhancing the vortex flow with a geometric fluid flow aid by further channeling the water around the wall of the fluid chamber, around the geometric flow aid. The method further includes continuing to introduce fluid to the chamber and collecting reconstituted fluid that exits the chamber through the effluent port.

The second actuator rotates the needles via the actuator holder. The needles are configured to be positioned, by the second actuator, at a container-facing position at which the needles face a culture container and a washing-facing position at which the needles face the washer.

This invention relates to a floating horizontal tubular photobioreactor system comprising a photosynthetically active area made of flexible tubes connected to rigid manifolds with an integrated system for mixing, aeration and degassing. This invention further relates to methods of using the floating photobioreactor system.

A photobioreactor system and a process for its use is illustrated, whereby water and nutrients from multiple sources are balanced (mixed using aeration) to the specific requirements of the particular photosynthetic organism strain used, sterilized, further mixed to balance the system and seeded with the photosynthetic microorganism, e.g. microalgae (dilution of a concentrated stock or added to an existing algal biomass). In accordance with such an embodiment, the algal biomass is then grown for a most efficient number of hours in a totally controlled environment where temperature (using aeration, an internal coil cooling system, or a combination thereof), pH (via CO.sub.2 delivery) and light delivery (using internal lighting directly inside the algal biomass) are optimized to the algal strain grown.
