Higher-order interaction inhibits bacterial invasion of a phototroph-predator microbial community
… cultures of the alga Chlamydomonas reinhardtii (phototroph) or the ciliate Tetrahymena thermophila (predator), but cannot invade a community where both are present. The invasion resistance of the algae-ciliate community arises from a higher-order (3-way) interaction that is unrelated to resource …

Gene Expression in Rhodopseudomonas Sphaeroides (Photosynthesis, Carboxylase, Membrane Biosynthesis
… in cell-free extracts from the facultative phototroph, Rhodopseudomonas sphaeroides. The in vitro protein synthesizing system was active when prepared from either aerobically or anaerobically grown cells. Optimal activity was dependent upon use of extracts prepared freshly from early …

Effect of Crude Oil on Light Attenuation and the Resulting Impacts on Marine Microbial Phototrophs and Heterotrophs
… in light intensity would affect microbial phototrophic community composition, which in turn would alter the heterotrophic community and potentially the rate of hydrocarbon degradation. Experiments were conducted using natural seawater with a crude-oil layer (but not in contact with), a …

Eukaryotic Parasites of Toxic and Bloom-forming Diatoms: Molecular insights in their diversity and physiology
… as clonal cultures in lab conditions than their phototroph counterpart. Only with the recent application of molecular ecology methods, we have started to gain deeper insights in the structure of complex microbial communities where heterotrophic protists, and especially putative parasites, …

Towards unveiling the Photoactive Yellow Proteins: characterization of a halophilic member and a proteomic approach to study light responses
… actually spans a wider spectrum of both phototrophic as well as non-photosynthetic bacteria. PYP from Salinibacter ruber is shown to be the first example of a truly halophilic PYP that is stabilized by ionic strength. Furthermore, illumination with blue light ignites a cyclic series of …

Dynamic aggregation and dispersal of Escherichia coli under cycles of feast and famine
… in our lab examining the dynamics of complex phototroph-heterotroph communities exhibiting fluorescence in multiple channels.

Antarctic phytoplankton and climate change using Holocene sedimentary DNA, fossils and chemical proxies.
… overgrowth in chilled storage, dampened phototroph signals (especially cyanobacteria), and the value of targeted hybridisation capture for chilled archives. Chapter 5 uses authenticated Maxwell Bay sedaDNA to reconstruct whole community turnover, link phytoplankton declines to increases …

Metagenomic analysis of the biodiversity and seasonal variation in the meromictic Antarctic lake, Ace Lake
… in summer and no sunlight in winter, on the phototrophs identified in the lake, indicating the importance of light-based primary production in summer to prevail through the dark winter. Analysis of viral data generated from the metagenomes showed the presence of viruses, including a ‘huge …
