TLDR
A photobioreactor using three concentric glass cylinders, with a light source mounted on the axis within them, with the culture of phototrophic microorganisms in the chamber between the outer cylinder and the middle one is described.Abstract:
A photobioreactor using three concentric glass cylinders, with a light source mounted on the axis within them is described. The space between two innermost cylinders is used as a waterjacket, while the culture of phototrophic microorganisms is in the chamber between the outer cylinder and the middle one. This chamber is also equipped with a stirrer. Rhodobacter capsulatus has been grown in the device at biomass concentration up to 550 mg/l without light limitation.read more

Microalgal biomass production and carbon dioxide sequestration from an integrated ethanol biorefinery in Iowa: a technical appraisal and economic feasibility evaluation.
TL;DR: In this article, a 50mgy ethanol biorefinery in Iowa was evaluated as a candidate for this process, and theoretical projections for the amount of land needed to grow algae in raceway ponds and the oil yields of this operation were based on the amounts of CO 2 from the ethanol plant.

Light-dependent utilization of organic compounds and photoproduction of molecular hydrogen by photosynthetic bacteria; relationships with nitrogen metabolism.
TL;DR: Light-dependent production of molecular hydrogen in the presence of utilizable citric acid cycle intermediates has been demonstrated in resting cell suspensions of Rhodospirillum rubrum, and evidence is presented in support of the conclusion that ammonia, or a derivative metabolite, acts as a repressor of synthesis of one or more required protein components.

Culture conditions and the development of the photosynthetic mechanism : ii. an apparatus for the continuous culture of chlorella.
Jack Myers,L. B. Clark +1 more
TL;DR: An apparatus has been developed which maintains a constant density of population of Chlorella by automatic dilution of the growing culture with fresh medium, and cells harvested from the apparatus in daily samples are highly uniform in rate of growth and rate of photosynthesis measured under arbitrarily chosen conditions.
