Phosphorus-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 کاملSterols from the Green Alga Ulva australis
Three new sterols, (24R)-5,28-stigmastadiene-3β,24-diol-7-one (1), (24S)-5,28-stigmastadiene-3β,24-diol-7-one (2), and 24R and 24S-vinylcholesta-3β,5α,6β,24-tetraol (3), together with three known sterols (4-6) were isolated from the green alga Ulva australis. The structures of the new compounds (1-3) were elucidated through 1D and 2D nuclear magnetic resonance spectroscopy as well as mass spect...
متن کاملCorrigendum: Biomineralization mediated by anaerobic methane-consuming cell consortia
Anaerobic methanotrophic archaea (ANME) play a significant role in global carbon cycles. These organisms consume more than 90% of ocean-derived methane and influence the landscape of the seafloor by stimulating the formation of carbonates. ANME frequently form cell consortia with sulfate-reducing bacteria (SRB) of the family Deltaproteobacteria. We investigated the mechanistic link between ANME...
متن کاملIsolation 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 کاملEvolutionary rescue of a green alga kept in the dark.
Chlamydomonas (Chlorophyta) can grow as a heterotroph on medium supplemented with acetate in the dark. A long-term experiment to investigate adaptation to dark conditions was set up with hundreds of replicate lines. Growth was initially slow, and most lines became extinct when transferred every few weeks. Some lines survived through the expansion of lineages derived from cells with extreme phen...
