    <link>http://biblioteca.universia.net/ficha.do?id=42526068</link>
    <description>In this thesis, detection of active water-borne bacteria was achieved by combining flow cytometry with vital dyes that characterise the metabolic status of cells. Following optimisation, these techniques were applied to investigate the activity of bacteria exposed to disinfection, both in the laboratory and in real systems. Raw and potable waters from various locations around South Australia were then analysed to investigate relationships between numbers of active bacteria and those detected ...</description>

    <description>Xylene, also known as dimethylbenzene is a monoaromatic hydrocarbon existing in three isometric forms: ortho, meta and para. It is widely used in paints, glues, printer ink, pesticides, in the leather and rubber industries, in histology labs and is a component of gasoline. The constant use of this compound may cause damage in the environment and to human health, owing to its toxicity. An alternative way of eliminating or minimizing these problems, is bioremediation, a technique that uses micr...</description>

    <description>The F[1]F[O]-ATP synthase found in bacteria, mitochondria, and chloroplasts is responsible for synthesizing ATP from the precursors ADP and P[i]. In bacteria, the enzyme is used to synthesize ATP when the electrochemical gradient of protons ([Delta][mu]H&amp;#8314;) or sodium ions ([Delta][mu]Na&amp;#8314;) is high, and the phosphorylation potential is low inside the cell. Conversely, the enzyme hydrolyses ATP to generate a [Delta][mu]H&amp;#8314; or [Delta][mu]Na&amp;#8314; when these gradients are low, and...</description>
