Na. Kireeva et al., ENZYMES OF NITROGEN-METABOLISM IN SOIL PO LLUTED WITH OIL, Izvestia Akademii nauk SSSR. Seria biologiceskaa, (6), 1997, pp. 755-759
The influence of oil pollution on activity of the nitrogen metabolism
enzymes in forest grey heavy loamy soil was studied for many years in
the field and laboratory. Oil pollution inhibited activity of protease
, asparaginase, glutaminase, as well as nitrate and nitrite reductases
, but enhanced activity of urease and hydroxylamine reductase. Aromati
c fractions of oil inhibited all studied enzymes of nitrogen metabolis
