Engineering heavy metal resistance in cyanobacteria Synechococcus elongatus PCC7942
… as the toxic heavy metal and the cyanobacterium Synechococcus elongatus PCC7942 was chosen as the model organism for its ability to be genetically engineered. This study tried different methods to generate heavy metal resistant cyanobacteria strains, including continuous exposure the culture to …

Iron limitation and the role of siderophores in marine Synechococcus
Marine cyanobacteria in the genus Synechococcus are widely distributed and contribute significantly to global primary productivity. In many parts of the ocean their growth is limited by a lack of iron, an essential nutrient that is virtually insoluble in seawater. To overcome this, Synechococcus …

The growth and stress response characterization of Synechococcus WH8109 cyanobacteria
… This research characterizes the growth of Synechococcus WH8109 in the laboratory. In the laboratory, cell culture densities of greater than 109 cells/mL with a doubling time of approximately 24 hours were achieved when grown at 28'C with a 24 hour light cycle in sea water and artificial …

Population dynamics and diversity of Synechococcus on the New England Shelf
Synechococcus is a ubiquitous marine primary producer. Our understanding of the factors that determine its abundance has been limited by available observational tools, which have not been able to resolve population dynamics at timescales that match response times of cells (hours-days). Development …

Quantitative characterisation of single-cell circadian rhythms in cyanobacteria Synechococcus elongatus
… any species. Here, we used the cyanobacterium *Synechococcus elongatus* to investigate the clock dynamics in individual cells otherwise masked in bulk studies. To do this, we developed a microfluidic setup, allowing us to carefully control cellular environments and quantify circadian gene …

A tetraklóretán, tetraklóretilén és triklóretilén Synechococcus PCC 6301 cianobaktériumra kifejtett hatásainak vizsgálata
… és tetraklóretán) hatását vizsgáltuk a Synechococcus elongatus (Synechococcus sp. PCC 6301) cianobaktérium növekedésére és élettani folyamataira. Az eredmények azt mutatják, hogy a kontroll tenyészethez képest mindhárom klórozott szénhidrogén növekedésgátlást okoz, már a kezelés …

Adaptive Mechanisms of an Estuarine Synechococcus based on Genomics, Transcriptomics, and Proteomics
… has been conducted for picocyanobacteria (i.e. Synechococcus and Prochlorococcus) in coastal and oceanic waters, little is known about those found in estuaries like the Chesapeake Bay. Synechococcus CB0101, an estuarine isolate, is more tolerant to shifts in temperature, salinity, and metal …

Genes and structural proteins of the phage SYN5 of the marine cyanobacteria, Synechococcus
… cyanobacteria of the genera Prochlorococcus and Synechococcus are numerically dominant photosynthetic cells in the large oligotrophic gyres of the open oceans, and contribute an estimated 30% to the oceanic photosynthetic budget. Cyanophages have been isolated which propagate on many strains of …

Interactions of cadmium, zinc, and phosphorus in marine Synechococcus : field uptake, physiological and proteomic studies
… (Cd), zinc (Zn), and phosphorus (P) in marine Synechococcus. Enriched stable isotope field uptake studies of 110Cd in the Costa Rica Upwelling dome, a Synechococcus feature, showed that uptake of Cd occurs in waters shallower than 40 m, correlates positively with chlorophyll a concentrations …

Identification and Characterization of a New Class of Bilin Lyases in Synechococcus sp. PCC 7002
… in Fremyella diplosiphon as cpeS and cpeT. In Synechococcus sp. PCC 7002, there are three cpeS-like genes (named cpcS, cpcU, and cpcV) and one cpeT-like gene (named cpcT). These genes were cloned, overexpressed, and purified from E. coli. The CpcS and CpcU proteins form a 1:1 complex and …

Investigation of natural and synthetic coupling of the circadian clock in the cyanobacterium Synechococcus elongatus
*Synechococcus* *elongatus*, owing to its possession of a simple, yet robust circadian clock, is a well-studied model for microbial chronobiology. However, historical tool limitations have left much still to learn about this clock, including definitive answers as to whether it exhibits coupling. …

Characterization of Enzymes Involved in Bilin Attachment to Allophycocyanin in the Cyanobacterium Synechococcus sp. PCC 7002
… allophycocyanin in the cyanobacterium Synechococcus sp. PCC 7002. Candidates for lyases responsible for attachment of phycocyanobilin to allophycocyanin are two cpeS-like genes termed cpcS and cpcU, and one cpeT-like gene termed cpcT. In vitro bilin attachment reactions were conducted …

Production of Copper-Complexing Ligands in Response to Elevated Concentrations of Copper in Marine <i>Synechococcus</i> spp.
<p><em>Synechococcus</em> spp. (marine cyanobacteria) are extremely sensitive to copper toxicity and can produce high-affinity ligands of unknown structure which form complexes with free cupric ion. These ligands may contribute to the biological control of the levels of free cupric ions in surface …

Strategies to enhance extracellular electron transfer rates in wild-type cyanobacterium Synechococcus elongatus PCC7942 for photo-bioelectricity generation
… initial cross comparison of the cyanobacterium Synechococcus elongatus PCC7942 against other exoelectrogenic cultures showed a hindered exoelectrogenic capacity. Nonetheless, in mediatorless biophotovoltaics, it outperformed the microalgae Chlorella vulgaris. Furthermore, the performance of S. …
