In aerobic environments and in photoautotrophic cyanobacteria, where oxygen is produced in the light reactions of photosynthesis [ 10], nitrogenase activity must be protected.
Nutrient rich media along with dark conditions improved the biomass production, and when media was nutrient deprived, higher biomass was produced in the presence of light.
A further source of supply is the aromatic-rich liquid fraction produced in the cracking of naphtha or light gas oils during the manufacture of ethylene and other olefins.
The results showed that the vertical velocity along the light path was produced in the condition of destabilization, which helps to achieve homogenous mixing of medium needed for microalgae growth.
Such damage to the DNA molecule can contribute to mutagenic lesions, and the ROS produced in the course of energy release after light absorption is responsible for inflammation of the skin and sunburn.
NASA chose a successor to the Hubble Space Telescope today, announcing that it would launch a next-generation space observatory in 2010 that would study light produced in the earliest days of the universe.
Kamiokande, a tank of half a million gallons of very pure water a mile deep in a zinc mine in Japan, had been built to record the disintegration of protons by registering the time and direction of flashes of light produced in the water by high-energy fragments flying away.
