Numerous labor intensive and time intensive techniques are currently available for RNA isolation, purification and quantification. Quantification of RNA samples is carried out by measuring their absorption at 260 nm, though the standard and integrity of RNA samples are generally based on gel electrophoresis followed by ethidium bromide visualizatio

Most organic waters consist of modest quantities of natural compounds. Aquatic microorganisms have advanced to use some of these compounds as foods. Microorganisms living in oxygenated waters use dissolved oxygen to oxidatively degrade the natural and organic compounds, releasing Power that is used for development and replica. Populations of these
