Nitrate Monitoring Articles

The effects of acidified-nitrite stress on the growth initiation and intracellular pH (pHi) of individual cells of Debaryomyces hansenii and Candida zeylanoides were investigated. Our results show that 200 µg/ml of nitrite caused pronounced growth inhibition and intracellular acidification of D. hansenii at an external pH (pHex) value of 4.5 but ...

The CLD 88 enables to detect down to pMol level (nitrite / nitrate levels in drinking water).The new sample tube we are using (type 1), is optimized for this application. The internal flow restriction ismade from stainless steel and it can be cleaned in an ultrasonic cleaner. The sample flow of 110 ml/minminimizes the effect of the helium bubbles in the liquid sampler, which results in very low ...

Every organism has different potential to accumulate NO3- from the environment. Nitrate reduction processes are perhaps most significant in maintaining water quality by alteration of nitrate to nitrite. A comparative study between the nitrate reductase NR activity of green and blue green algae in presence of heavy metals is being conducted to present a situation where nitrate reductase process ...
