Formation of Large Thioredoxin / Accompanies Chloroplast Development in Scenedesmus obliquus
Chloroplast-free mutant cells C-2A ' of the green algae Scenedesmus obliquus lack thioredoxin / , which functions in the light activation of chloroplast enzymes, but do con tain the regular thioredoxins I and II. When dark-grown algae are transferred to light, thioredoxin / activity appears rapidly and increases in parallel with photosynthetic ac tivities; however it precedes chlorophyll bios...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Transfer ribonucleic acid from Scenedesmus obliquus D3.
Scenedesmus obliquus is a green alga whose cells have a well-defined nucleus, and contain a chloroplast. Even when grown in the dark these cells retain their chloroplast. Because of the toughness of the cell wall, extraction of tRNA requires either vigorous homogenization of the cells before phenol extraction or prolonged phenol extraction at 60°C. Determination of the amount of tRNA and its pu...
متن کاملInfluence of phosphorus concentration on the growth kinetics and stoichiometry of the microalga Scenedesmus obliquus
The growth of the freshwater microalga Scenedesmus obliquus was studied at 30°C in a mineral culture medium with phosphorus concentrations of between 0 and 372 pro. The values for the specific growth rates, between So=0 #m and S,=298 pro, fitted a semistructured substrate-limitation model with #,,~ = 0.0466 h P.,,2 = 0.0256 h ~ and Ks = 0.2 ttm. The specific uptake rate of phosphorus reached a ...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
