Problems solved by technology

Although small diameter tubes were found to maximize the use of captured sunlight, strong turbulence was required, and in addition, high pumping pressures were required to maintain the necessary flow rates through the length of the tube, making the system more expensive

Abstract

According to embodiments of the present invention, a bioreactor for growing photoautotrophic organisms is provided. The bioreactor includes a vessel configured to receive the photoautotrophic organisms, the vessel having a longitudinal axis, which a circumferential wall extends around said axis, wherein said circumferential wall is translucent so as to enable light to enter the vessel from the outside for acting on the photoautotrophic organisms, wherein a device for providing an uneven distribution of the light intensity within said vessel along said axis is provided.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Application No. 61 / 577,547, filed December 19, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] Various embodiments relate to a bioreactor. Background technique [0004] Crude oil reserves are rapidly dwindling. Currently, the cultivation of photoautotrophs such as microalgae has been identified as a potential strategy to deal with the major problems mentioned above. Microalgae can be used as an alternative feedstock for biofuel production. Unlike rapidly dwindling crude oil reserves, microalgae are renewable and provide rapid growth. Microalgae potentially provide high oil yields at low raw material costs due to high lipid triglycerides of up to 80% dry weight and fast exponential growth rates compared to the high vegetable oil costs commonly observed in biodiesel production . In add...
