The fine-structure and taxonomy of the haptophycean flagellate …
2009年5月11日 · Since its original isolation and description by Droop in 1953, ‘ Monochrysis’ lutheri has proved to be one of the most valuable of cultured phytoflagellates. It has been used by many workers, too numerous to cite, in laboratory studies on phytoplankton growth kinetics, nutrition and biochemistry, and also in mariculture and animal feeding ...
Vitamins, phytoplankton and bacteria: symbiosis or scavenging?
2007年1月19日 · Vitamins, phytoplankton and bacteria: symbiosis or scavenging? The conclusion that over 25% of global primary production depends on direct algal/bacterial symbiosis involving vitamin B 12 [ Croft et al., (2005) Algae acquire vitamin B 12 …
Combined effects of nutrients and grazers on bacterioplankton …
2008年12月2日 · The manipulation of different plankton size fractions and nutrient concentrations in the microcosms hinted at relevant interactions between the microbial and classic food web components in Lake Chico. The response of bacterioplankton to changes in the presence of grazers and nutrient concentrations differed from that of picophytoplankton.
Taxonomy and phylogeny of the section - Springer
2024年2月22日 · Monoclonal strains of the section Chaetoceros were established, morphological features were studied using light and electron microscopy, and the hypervariable D1–D3 region of the nuclear ribosomal large subunit gene was sequenced to address phylogenetic relationships.
Fractionation of stable carbon isotopes by marine phytoplankton
1978年12月1日 · A temperature dependent fractionation of 0.36% per °C with decreasing temperatures was measured for Skeletonema costatum whereas, smaller temperature dependencies of −0.13, +0.15 and −0.07%. per °C were observed for Dunaliella sp., Monochrysis lutheri and Glenodinium foliaceum, respectively.
2019年5月10日 · Two species of Synechococcus elongatus and Chlorella sp. were evaluated as excellent food plankton, four species of Chlamydomonas sp,, Monochrysis lutheri, Dunaliella tertiolecta and Cyclotella cryptica as average and two species of Eutreptiella sp. and
However, a study of plankton growth kinetics would appear to be the logical place to begin this modeling approach. A goal of our plankton studies is to measure quantitatively the changes in natural plankton communities in response to well-defined natural changes of the physical and chemical environ-ment. In principle the study of the kinetic
The unsteady continuous culture of phosphate-limited Monochrysis ...
1979年6月14日 · Steady-state and short-term uptake experiments with unialgal cultures of Monochrysis lutheri Droop, a marine chrysophyte, were used to calibrate the proposed model. For the long-term unsteady experiments, the model predicts well the culture's dynamic response in terms of cell density to steps down and up in influent concentration of limiting ...
Photosymbiosis in Marine Planktonic Protists | SpringerLink
Recent technical advances in single-cell genomics and imaging have greatly improved our understanding about planktonic symbioses. This review aims to present and compare many eukaryote–eukaryote and eukaryote–prokaryote photosymbioses described so far in the open ocean with an emphasis on their ecology and potential function in the ecosystem.
We experimen-tally tested the effects of warming on 12 species of phytoplankton isolated from a variety of environments by using a mechanistic approach able to assess evolutionary adaptation (the so-called ratchet technique). We found different degrees of tolerance to temperature rises and an interspecific capacity for genetic adaptation.
