Compound From Cyanobacterium Can Fight Alzheimer’

Alzheimer's and other types of neurodegenerative diseases can be countered by a compound which is derived from cyanobacterium, a type of blue-green algae known as Nostoc // . This has been revealed by researchers from Switzerland. According to the study, published in the recent issue of issue...

New research provides dynamic visualization of simplest circadian clock

... essential components of the circadian oscillator in cyanobacteria are the three clock proteins KaiA, KaiB and KaiC, all of which are expressed in the cyanobacterium S. elongatus. Considerable research has implicated the phosphorylation cycle of KaiC as the central pacemaker in cyanobacteria and has demonstrate...

Dust deposited in oceans may carry elements toxic to marine algae

... researchers tested the effects of different concentrations of copper on a dominant species of phytoplankton in the seawater. The organisms (a type of cyanobacterium called Synechococcus) died at the same copper concentrations found in the aerosols. Other studies compared different species of phytoplankton and foun...

Photosynthesizing bacteria with a day-night cycle contain rare chromosome

...eins revealed more genes on the linear and the typical circular chromosomes then they'd have found with DNA sequencing alone.

Single-celled bacterium works 24-7

...n University in St. Louis have gained the first detailed insight into the way circadian rhythms govern global gene expression in Cyanothece, a type of cyanobacterium (blue-green alga) known to cycle between photosynthesis during the day and nitrogen fixation at night. In general, this study shows that during th...

New source for biofuels discovered

... R. Malcolm Brown Jr. and Dr. David Nobles Jr. secrete glucose and sucrose. These simple sugars are the major sources used to produce ethanol. The cyanobacterium is potentially a very inexpensive source for sugars to use for ethanol and designer fuels, says Nobles, a research associate in the Section of Microbi...

Researchers visualize complex pigment mixtures in living cells

...With the method, they showed that photosynthesis-related pigments (chlorophylls, phycobilins and carotenoids) can be localized in vivo in cells of the cyanobacterium Synechocystis sp. PCC 6803 through deconvolution of individual fluorescence emission spectra in small (0.03 cubic micrometer) volumes by means of hype...
