The prospect function of terrestrial nitrogen-fixing Blue–Green Algae on the fixation of desertEcosystems Dynamics Ecosystem-Society Interactions and Remote Sensing Applications for Semi-Arid and Arid Land, 2003Co-Authors: Yusuo YangAbstract:
ABSTRACT The Terrestrial Nitrogen-fixing Blue–Green Algae, which are possessed of both photosynthesis and nitrogen fixation, are the leading organisms in the adverse circumstances. With their typical cell structures and physiological abilities, they are strongly resistant to drought, infertility etc. The growth of Terrestrial Nitrogen-fixing Blue–Green Algae can rich the soils in nitrogen and organic compounds, which are benefit to other microbes and plants. Terrestrial Nitrogen-fixing Blue–Green Algae are widely distributed in Gurbantunggut Desert. It was estimated that about 40% of the surface of the desert are covered by the Black Crust. Black Crust is mainly occupied by Terrestrial Nitrogen-fixing Blue–Green Algae. It is Terrestrial Nitrogen-fixing Blue–Green Algae that construct the mechanical crust with a little other Algae and fungi through biological, chemical and physical actions. So Terrestrial Nitrogen-fixing Blue–Green Algae play an important part in desert fixation. It was analyzed that there are three species of the Blue–Greens in the Black Crust: Microcoleus vaginatus(Vauch)Gom.,Scytonema ocellatum Lynbye and Schizothrix mella Gardner. We had isolated Microcoleus vaginatus(Vauch)Gom.and Scytonema ocellatum Lynbye . Some tests had been made to prove the feasibility of the desert fixation of the Blue–Greens. Under experiment conditions, the Blue–Greens grown on the surface of sand, covered the sand quickly after the inoculation, and formed a mechanical fixed surface layer (7 days for Microcoleus vaginatus, 15-21days for Scytonema ocellatum ). Key words: Terrestrial Nitrogen-fixing Blue–Green Algae; Environmental Effect; Desert Fixation

Nitrogen-Fixing Blue—Green AlgaeThe Nitrogen Fixation and its Research in China, 1992Co-Authors: S. H. LeyAbstract:
Blue—Green Algae (Cyanobacteria) are a special group of prokaryotes. They have chlorophyll and phycobiliprotein and can fix carbon by oxygen-evolution photosynthesis like plants; and their genome contains nucleotide sequences which are comparable with that of 16S and 5S rRNA of cubacteria. Therefore, in tradition, they are called Cyanophyta (Myxophyta, Cyanophyceae), but in the recent decade, they are also called Cyanobacteria. (According to the “Manual of Systematic Bacteriology” Vol. 3 (1989), they can be called cyanobacteria or Blue—Green Algae or Cyanophyceae). For convenience, I use BGA (Blue—Green Algae) for these prokaryotes in this paper. BGA are widely distributed all over the earth. While fixing carbon from CO2, certain BGA can fix dinitrogen from the atmosphere, and are called nitrogen-fixing BGA, including free living and symbiotic forms.

Meteorological Condition of Blue–Green Algae Fast Growth of Lake Tai in 2007Journal of Anhui Agricultural Sciences, 2008Co-Authors: Ren JianAbstract:
[Objective] The research aimed to study main meteorological factors of Blue–Green Algae fast growth of Lake Tai in 2007.[Method] The data of Dongshan weather station in 2007 was deputy to analyze the relationship between same history time meteorological conditions and the time of Blue–Green Algae fast growth.[Result] Continuance higher temperature and enough sunshine supplied safeguard on the quantity of heat for the growth of Blue–Green Algae.Few rain and low mean wind supplied safeguard for the granule of Blue–Green Algae on the surface and conglomeration.[Conclusion] The climate anomaly aroused Blue–Green Algae fast growth of Lake Tai in 2007.So,the study of the relationship between meteorological condition and Blue–Green Algae fast growth of Lake Tai should be strengthened so as to improve the ability of weather forecast.
