Description
Enumerate all culturable microorganisms from water using colony count technique this medium while conforming to ISO 6222: 1999.
Waters of all kinds invariably contain a variety of microorganisms derived from various sources, such as soil and vegetation. Estimation of the overall numbers provide useful information for the assessment and surveillance of water quality. Separate counts are usually made of the microorganisms which are able to grow and form colonies on nutrient agar media at 36°C and 22°C.
Colony counts are useful for assessing the integrity of ground water sources and the efficiency of water treatment processes such as coagulation, filtration and disinfection and provide an indication of the cleanliness and integrity of the distribution system. They can also be used to assess the suitability of a water supply for the preparation of food and drink to avoid contaminating the product with spoilage organisms.
The main value of colony counts lies in the detection of changes from expected counts, based on frequent, long term monitoring. Any sudden increase in the count can be an early warning of serious pollution and a call for immediate investigation.

Questions about Water Plate Count Agar (Dehydrated), 500 g
What is this article?
Water Plate Count Agar (Dehydrated), 500 g is the article on this page. Luminix Health distributes Altmann Analytik for laboratory use. It sits in Ready-to-use culture media (plates, tubes, bottles), inside Culture media & microbiology, in Life Science & Microbiology.
A ready-to-use plate, tube or bottle is the medium already prepared and sterile. It saves the autoclave and it expires. The fill volume, the supplements and the storage temperature are the specification. A plate that has dried out or grown a colony of its own is finished.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
