Photochromism ofAnabaenaSensory Rhodopsin
Journal of the American Chemical Society, 2007Protein-controlled photochemical reactions often mediate biological light-signal and light-energy conversions. Microbial rhodopsins possess all-trans or 13-cis retinal as the chromophore in the dark, and in the light-driven proton pump, bacteriorhodopsin (BR), the stable photoproduct at the end of the functional cycle of the all-trans form is 100% all ...

Tungsten-induced inactivation of molybdoenzymes in Anabaena
Biochimica et Biophysica Acta (BBA) - Enzymology, 1980The effect of tungsten on growth and activity of two molybdoenzymes has been studied in a nitrogen-fixing heterocystous cyanobacterium, Anabaena. Sodium tungstate inhibited growth and inactivated nitrogenase and nitrate reductase. The activity of both enzymes was restored by the addition of molybdenum.

Action of lysozyme on Anabaena ambigua Rao
Archiv f�r Mikrobiologie, 1973Lysozyme attacks the walls of the vegetative cells and produces protoplasts. The wall of the heterocyst is not affected, but the polar region is elongated linearly to form thick and long stalks. Unequal elongation of the stalks results in the pushing out of the protoplast from the shell of the heterocyst.

The Azolla — Anabaena Azzolae Symbiosis
1977Free-living, nitrogen fixing blue-green algae occur in soils and in both fresh water and marine habitats from the tropics to the antarctic.l–3 Moreover, symbiotic relationships with nitrogen-fixing blue-green algae encompass members of a relatively large and diverse segment of the plant kingdom.

Anabaena azotica FACHB-118 and Anabaena sp. CH1, heterocystous cyanobacteria isolated from Chinese and Taiwanese rice fields, expressed vanadium-containing nitrogenase when under molybdenum deficiency. This is the second direct observation of an alternative nitrogenase in cyanobacteria.

Photostimulation of nitrogen fixation in Anabaena cylindrica
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1970Abstract Photostimulation of N 2 fixation in the blue-green alga Anabaena cylindrica was investigated using monochromatic light and by comparing action spectra of C 2 H 2 reduction with that of photosynthetic O 2 evolution. Maximum nitrogenase activity per unit energy was measured at a wavelength which corresponds to the maximum light absorption

The nitrogen-fixing filamentous cyanobacterium A. thermalis SpA was isolated from the-surface of wild rice growing in Viet Nam. Electron microscopy shows that the purified strain is able to penetrate into the root interior of surface sterilized rice plants. Attempts have been initiated to genetically manipulate A.

ในปัจจุบันการใช้ประโยชน์ของพอลิเมอร์ชีวภาพรวมถึงพอลิแซคคาไรด์และ พอลิไฮดรอกซีบิวทิเรตในการทดแทนวัตถุดิบจากปิโตรเลียมได้รับความสนใจอย่างกว้างขวาง เนื่องจากระดับความตระหนักต่อสิ่งแวดล้อมเพิ่มสูงขึ้น อย่างไรก็ตามข้อจำกัดทางการค้าของ พอลิเมอร์เหล่านี้ คือ ปริมาณการผลิตต่ำ ดังนั้นการศึกษาในครั้งนี้จึงมีวัตถุประสงค์เพื่อศึกษาการผลิต พอลิแซคคาไรด์และพอล ...openaire +1 more source
Bacteria in the Azolla-Anabaena symbiosis
1989The leaf cavities of the fern Azolla contain the N2-fixing cyanobacterium Anabaena Azollae Strasb. and bacteria. These bacteria have been isolated from five Azolla species, grown in the Botanic Garden of Naples, Italy; they were aerobic, Gram-positive and with a rod-coccus life cycle. Moreover they neither fixed nitrogen nor produced gas, H2S or indole,
