Expression of the ggpS gene, involved in osmolyte synthesis in the marine cyanobacterium Synechococcus sp. strain PCC 7002, revealed regulatory differences between this strain and the freshwater strain Synechocystis sp. strain PCC 6803

Article Abstract:

Research is conducted on the osmolyte glucosylglycerol biosynthesis of cyanobacterium Synechococcus sp. strain PCC 7002 isolated from marine environment to compare the results with the results for the freshwater organism Synechocystis sp. strain PCC 6803. Experiments revealed differences in their protein regulation.

New and fast method to quantity respiration rates of bacterial and plankton communities in freshwater ecosystems by using optical oxygen sensor spots

Article Abstract:

A new method is developed for respiration rate measurement that is based on oxygen luminescence quenching in sensor spots for aquatic bacterial communities. Studies have shown that the contribution of bacterial respiration to the total plankton community oxygen consumption has varied seasonally between 11 and 100%.

Detection of Prochlorothrix in brackish waters by specific amplification of pcb genes

Article Abstract:

Research demonstrates the occurrance of the genus Prochlorothrix in brackish water environment as shown by the detection of DNA fragments with high sequence similarity to the pcb gene encoding chlorophyl b binding proteins of the freshwater species P. hollandica.
