The effect on oxygen evolution of Chlorella vulgaris produced by light intensities up to ab f.-c. has been studied by the use of the Warburg technique. 2. Above a certain critical intensity, which is determined by the previous history of the cells, the rate of oxygen evolution decreases from the maximum to another constant by:

After 4 days' growth the cultures were concentrated by centrifugation at Cited by: Full text Full text is available as a scanned copy of the original print version.

There are few determinations of quantum numbers for photosynthesis in leaves of higher plants. Nothing is known about the number of quanta required to evolve one. Cited: 1. BRISTOL ROACH, B. On the influence of light and of glucose on the growth of a soil alga.

Unicellular green algae, such as Chlorella and Scenedesmus, have been artificially cultivated, yielding 75 tons per hectare (30 tons per acre) per year, compared with the standard wheat yield of to tons.

However, the process is costly, since algae, in addition to harvesting, require decolorization and special processing. Measurement of Net and Gross Photosynthesis. Gas-exchange equations predict that net assimilation (A net) increases linearly at low light intensity, where light is limiting, and plateaus at high light levels, where CO 2 assimilation is limited by Rubisco Figure 1, the linear portion of the curve is restricted to light intensities lower than μmol m −2 s − by: 9.

The inhibition of both respiration and photosynthesis in Chlorella pyrenoidosa by thiourea and salicylaldoxime was re- versible. The initial rates were fully restored after 4 hours dialysis and centrifuging. The ascorbic acid content of centrifuged. Many plants live through photosynthesis, and the source of a life is solar energy in animals and plants alike.

The daily yield of 20 grams per square meters indicates that Chlorella produces much more organic matter than regular plants. If we assume one gram of Chlorella has kcal, the yearly calories will be 40, kcal per square meter.

The mitochondrial electron transport chain includes an alternative oxidase ([AOX][1]) that is hypothesized to aid photosynthetic metabolism, perhaps by acting as an additional electron sink for photogenerated reductant or by dampening the generation of reactive oxygen species.

The most ambitious of these is the long awaited Volume II of Photosynthesis and Related .It is also shown that the low quantum yield of oxygen evolution is replaced by high yield when supplementary light is added even in the red drop region (the Emerson enhancement effect).

Note that the maximum quantum yield is (or 1 oxygen molecule per minimum of 8 photons absorbed), as observed by R. Emerson & coworkers, but not or.
