Enzymatic Biosynthesis of Novel Resveratrol Glucoside and Glycoside Derivatives.

abstract：:Nitrification in chloraminated drinking water can have a number of adverse effects on water quality, including a loss of total chlorine and ammonia-N and an increase in the concentration of heterotrophic plate count bacteria and nitrite. To understand how nitrification develops, a study was conducted to examine the fa...
