Uptake hydrogenase in cyanobacteria: novel input from non-heterocystous strains.
Most of the research to date on cyanobacterial uptake hydrogenases has been performed on filamentous heterocystous strains. However, recent results on the hup gene cluster organization and its transcriptional regulation in non-heterocystous strains has contributed to the widening of knowledge in this field. In the present study, we outline the recent findings on uptake hydrogenases from non-het...
متن کاملNitrogenase, Hydrogenase and Hydrogen Production by Cyanobacteria
2 Summary Hydrogen has the potential to provide a clean, storable, transportable and renewable source of energy that can meet the need for power throughout the world. Biological production of hydrogen, especially by photosynthetic microorganisms that use sunlight for energy, provides a renewable source of hydrogen for fuel cells. Nitrogen-fixing cyanobacteria can produce hydrogen in an aerobic ...
متن کاملNitrogen Fixation Genes and Nitrogenase Activity of the Non-Heterocystous Cyanobacterium Thermoleptolyngbya sp. O-77
Cyanobacteria are widely distributed in marine, aquatic, and terrestrial ecosystems, and play an important role in the global nitrogen cycle. In the present study, we examined the genome sequence of the thermophilic non-heterocystous N2-fixing cyanobacterium, Thermoleptolyngbya sp. O-77 (formerly known as Leptolyngbya sp. O-77) and characterized its nitrogenase activity. The genome of this cyan...
متن کاملNitrogenase Gene Amplicons from Global Marine Surface Waters Are Dominated by Genes of Non-Cyanobacteria
Cyanobacteria are thought to be the main N(2)-fixing organisms (diazotrophs) in marine pelagic waters, but recent molecular analyses indicate that non-cyanobacterial diazotrophs are also present and active. Existing data are, however, restricted geographically and by limited sequencing depths. Our analysis of 79,090 nitrogenase (nifH) PCR amplicons encoding 7,468 unique proteins from surface sa...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
