2015) by determination of p- nitrophenol
released on incubation of soil with respective substrate: [beta]- glucopyranoside, p- nitrophenyl sulfate and p-nitrophenyl phosphate (Dick et al.
All results are expressed in U/ml which is defined as 1 nmol of 4- nitrophenol
formed per minute.
lethal doses (lD50) of nitrophenol
orally administrated to rats and mice are 450-850 mg/kg and 380 mg/kg of body weight, respectively, and for dinitrophenol (rats) only 30 mg/kg of bodyweight .
TEHRAN (FNA)- Iranian researchers from Tehran University of Medical Sciences succeeded in the enzyme degradation of nitrophenol
pollutants by using porous silica beads.
By the electroreduction  of nitrophenol
isomer using stationary and rotating Cu electrodes and Ti(S04)2 as additional agent, aminophenols were obtained in good yield.
Degradation of nitrophenol
under sonication can lead to defacement of ester hydrolysis kinetics and this issue has been discussed in detail in our previous paper .
Activity against [beta]-N acetylglucosamide and G mannopyranoside, using para nitrophenol
(pNP) conjugates showed that chlamydia expressed high levels of [beta]-N acetylglucosaminidase and G mannosidase.
Nonspecific esterase activity was measured as the average change in optical density per minute at 400 nm and then converted to units (micromoles of 4-NPC hydrolyzed per minute) using the extinction coefficient for nitrophenol
of 19,800 [M.
can be confirmed either visually on the basis of a yellow color or by optical spectrometry at its absorption peak of 420 nm.
