Question

Mention Three methods used to promote the microbiological quality of water and how they affect microorganisms.

Answer 1

Answer=

Methods used to promote the microbiological quality of water as follows:

1] Fluorescence measurements - The origin and contamination ,type of dissolved organic matter has been characterized by fluorescence.

for example-in river water samples,both protein like(Tyrosine and tryptophan like) and fulvic -like and humic like fluorescence were detected.

2] Biosensors= Biosensors combining the selectivity of biology with the processing power of microelectronics may also considered through bio-recognition systems,generally enzymes or binding proteins such as immobilized antibodies.

Biosensors have been reported employing the full spectrum of biorecognition molecules and transduction methods for detection of waterborne pathogens ,with oligonucleotide probes and antibodies.

3]Spectrophotometric methods= is interesting for the detection of microbial contamination because of their use in particle characterization.

use for quantitative assessment of particle concentration in sea water.
