the efficiency of photosynthesis

sphaeroides has been identified as the bacterium having the highest hydrogen-producing rate (260 ml/mg/h) (7), with a photoenergy conversion efficiency (energy yielded by combustion of produced hydrogen/incident solar energy) of 7%, determined using a solar simulator (7, 8).

efficiency of photosynthesis ..

Plant photosynthesis takes place only in the presence of visible light (400-700 nm).

photosynthetic nitrogen-use efficiency;

In this study, Professor Sonoike measured chlorophyll fluorescence using a pulse-amplitude modulation (PAM) fluorometer to analyze photosynthesis in C. paradoxa, without destroying the cells, and check its interactions with metabolic reactions such as respiration. The application of such technique to algae is not easy, but being an expert in measuring fluorescence in cyanobacteria, Professor Sonoike successfully adapted the method to this research.

To increase the efficiency of photosynthesis, ..

"Such concave light dependence was quite similar that observed in cyanobacteria," points out Professor Sonoike. "Although glaucophytes perform photosynthesis and respiration separately with respective organelles unlike cyanobacteria, similar metabolic interactions are observed in both organisms."

The fact that photoelectric charge isolation is observed in protein molecules will greatly influence future research relevant to molecular elements and solar batteries.



Although large amounts of solar energy are irradiated to the earth's surface, the actual concentration (energy/unit area) of solar energy at the earth's surface is relatively low.

Photosynthetic bacteria are also capable of reducing electron carriers such as NAD, via a linear reaction similar to the electron transmission which occurs during plant photosynthesis (Figure 2-2).

Unlike in the case of plant photosynthesis, cyclic photophosphorylation takes place in bacterial photosynthesis, i.e.

crop yield is limited by the efficiency of photosynthesis ..

Recent advances in biotechnology have made possible studies on the utilization of biological processes such as photosynthesis for energy production.The use of natural energy involves the control of entropy.

The accumulation of solar energy for practical use, therefore necessitates collection of solar energy over large areas.

Figure 2.2 - Schematic representation of mechanisms involved in bacterial photosynthesis CO2-fixing reactions do not produce energy during bacterial photosynthesis (i.e equimolar amounts of organic compounds are produced through decomposition of organic compounds), except when sulfur compounds serve as electron carriers.

This could potentially be a costly venture, particularly with respect to the use of solar batteries for solar energy concentration.

The use of hydrogen is also advantageous in that when burnt it yields only water, and hence does not contribute to environmental pollution.

Cyanobacteria (blue-green algae) and photosynthetic bacteria are representative photosynthetic hydrogen producers.
