Sulfate Reducing Bacteria (SRB) are those bacteria that can obtain energy by oxidizing organic compounds or molecular hydrogen while reducing sulfate to hydrogen sulfide. They are also know as Sulfide Generating Bacteria (SGB) and commonly found in anaerobic environments where they aid in the degradation of organic materials like secondary oil recovery effluents, estuarine waters, deep wells, cooling waters, metalworking fluids, water-based hydraulic fluids, and petroleum based products. They can survive up to 600 DegC & cause pitting corrosion on metal structures that are exposed to sulfate-containing water by cathodic depolarization. They also play a role in the anaerobic oxidation of methane below the seabed in the transition zone which leads to heavy production loss.

Since sulfate is also found in some formulations of or the other used in water treatment, viz, corrosion inhibitors, coolants, etc. Sulfate acts as a hydrogen acceptor produces hydrogen sulfide and ferrous sulfide. These together form a malodorous black slime. In some case bubbles of H2S rise though the water and cause objectionable odors. The corrosion of iron by sulfate reducing bacteria is rapid and unlike ordinary rusting, is not self limiting. Our specially developed test kit with a unique 10ml sample size gives a much detailed quantitative analysis of the SRB count in a sample. BACTASLYDE SRB is supplied in boxes of 5 along with the complete instructions set for a complete quantitative analysis of the contamination.

Soil testing is the analysis of a soil sample to determine nutrient and contaminated content, composition, and other major nutrient characteristics. A soil test can determine fertility, or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility and inhibitions from the presence of non-essential trace minerals.

Soil testing is often performed targeting groups of compounds and minerals which need to be in adequate quantities for the soil to be productive and subsequently give a healthy crop. The advantages of testing are that excessive use of fertilizer can be avoided which results in reduction of Waste of plant & potential damage to environment can be controlled. Therefore it makes good sense to test the soil for these nutrients and add the required amount of fertilizer.

Soil has to contain some major nutrient for the crops to be healthy. The major nutrients which need to be in adequate quantities for the soil to be productive and subsequently give a healthy crop are:

NITROGEN

Nitrogen encourages above ground vegetative growth & it serves as the source for the dark green color in the leaves of various crops.

PHOSPHOROUS

Phosphorus is a component of the complex nucleic acid structure of plants, which regulates protein synthesis. It is therefore, important in cell division and development of new tissue in roots.

POTASSIUM

Potassium takes care of multiple functions like Photosynthesis, Protein Synthesis, and Starch formation and for the translocation of Sugars. It also imparts resistance to the plant against Microbial attack and if deficient results in poor flowering and fruit formation.

pH

pH is important because it influences how easily plants can take up nutrients from the soil. Also is useful in prevention of soil borne disease.

ORGANIC CARBON

Carbon content of soil is a major factor in its overall health. Soil carbon improves the physical properties of soil and water-holding capacity of sandy soil. Also it contributes to the structural stability of clay soils by helping to bind particles into aggregates of which carbon is a major part, holds a great proportion of nutrients that are of importance to plant growth. It prevents nutrient leaching, and is integral to the organic acids that make minerals available to plants.

The first thought that comes to mind when we think of safety in swimming pools is drowning, slipping and falling, etc.

But do we really know that the most probable hazard is contamination by germs, viz. bacteria. Therefore the likelihood of us falling prey to these sicknesses is much more than that of drowning, etc. Bacteria spread through people, who have diarrhoea and as the pool is shared by many swimmers, it can be very easily be contaminated. Even best maintained swimming pools can spread illnesses due to these microscopic predators, the bacteria. Therefore to ensure a disease free swimming experience, regular disinfection of the water is essential.

Generally, Chlorine is the disinfectant of choice and a residual has to be maintained to ensure complete disinfection as well as residual protection. Now for Chlorine to be effective, the pH (Hydrogen Ion Concentration) of the water should preferably be between pH 6.5 to 7.5. Water below pH 6 or above pH 8 could be uncomfortable for skin.

Now to be doubly sure that the chlorine dose is effective, monitoring of harmful bacteria content is essential. However, detection of these unseen predators is always a tedious and time consuming task, in a laboratory, by the conventional methods of microbiology. Now our AQUASOL Swimming Pool Test Kit helps in testing pH, Chorine & Bacteriaby anyone, anywhere in a matter of a few minutes. Our ready to use kits helps to monitor the levels of Chlorine & pH on daily basis as well as has tests for harmful disease causing bacteria.
