Isolation and structure elucidation of a new alkaloid from the Indonesian Blue-Green Alga Arthrospira platensis
A new alkaloid (1) and two known compounds (2 and 3) were isolated from the blue-greenalga Arthrospira platensis. Their structures were determined on the basis of spectroscopic data.According to the obtained data and values in the literature, the compounds were concluded to beeckol.
متن کاملPhosphorus-limited growth of a green alga and a blue-green alga.
The phosphorus-limited growth kinetics of the chlorophyte Scenedesmus quadricauda and the cyanophyte Synechococcus Nägeli were studied by using batch and continuous culturing techniques. The steady-state phosphate transport capability and the phosphorus storage capacity is higher in S. Nägeli than in S. quadricauda. Synechococcus Nägeli can also deplete phosphate to much lower levels than can S...

متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولFactors influencing dark nitrogen fixation in a blue-green alga.
Nitrogen-fixing activity declines first rapidly and then more gradually when Anabaenopsis circularis is transferred from light into dark conditions. The rate and duration of dark acetylene reduction (nitrogen fixation) depend upon conditions prevailing during the preceding light period. Factors (such as light intensity, CO2 concentration, and supply of glucose), which in the light affect photos...
