Photobioreactor

A photobioreactor comprising a receptacle with a first and a second outer side surface, wherein the receptacle is formed from a flexible, fluid-tight and transparent material, wherein the receptacle is disposed in a rack provided with elongated, substantially vertical, support elements arranged in at least one horizontal row, whereby the support elements abut, in an alternating and supporting manner, against the first and the second outer side surfaces of the receptacle;

• wherein the support elements are arranged in two rows;
• wherein the support elements in a first row are offset horizontally relative to the support elements in a second row.

A photobioreactor comprising a receptacle with a first and a second outer side surface, wherein the receptacle is formed from a flexible, fluid-tight and transparent material, wherein the receptacle is disposed in a rack provided with elongated, substantially vertical, support elements arranged in at least one horizontal row, whereby the support elements abut, in an alternating and supporting manner, against the first and the second outer side surfaces of the receptacle;

• wherein at least every other support element is movably positionable with respect to the frame in a direction perpendicular to a center line.

A photobioreactor comprising a receptacle with a first and a second outer side surface, wherein the receptacle is formed from a flexible, fluid-tight and transparent material, wherein the receptacle is disposed in a rack provided with elongated, substantially vertical, support elements arranged in at least one horizontal row, whereby the support elements abut, in an alternating and supporting manner, against the first and the second outer side surfaces of the receptacle;

• wherein at least every other support element is rotatable with respect to a vertical longitudinal axis of the support element towards and away from the center line.

A photobioreactor comprising a receptacle with a first and a second outer side surface, wherein the receptacle is formed from a flexible, fluid-tight and transparent material, wherein the receptacle is disposed in a rack provided with elongated, substantially vertical, support elements arranged in at least one horizontal row, whereby the support elements abut, in an alternating and supporting manner, against the first and the second outer side surfaces of the receptacle;

• wherein an upper frame element is provided with means for positioning the receptacle in the vertical direction;
• wherein the upper frame element is provided with at least two suspension mechanisms, and each suspension mechanism is comprised of at least two ball transfer units with balls, the free portion of the balls forming substantially a vertical gap.

A photobioreactor comprising:

• a fluid-containing receptacle having opposing first and second outer side surfaces that are formed of a flexible transparent material;
• and
• a rack supporting the receptacle, the rack comprising vertical support elements that are spaced apart along a center line, and that abut the first and second outer side surfaces of the receptacle such that at each location along the center line, only one support element abuts the receptacle.
