次脲基 的英文怎麼說
中文拼音 [cìjī]
次脲基
英文
ureylene-
The activity of urease is hard to recover entirely with regeneration solution after contacting inhibitors for many times. for this reason, a renewable urease biosensor is highly desired. in chapter 3, a renewable potentiometric urease inhibition biosensor based on self - assembled gold nanoparticles has been developed for the determination of mercury ions
2 .重金屬離子對脲酶的抑制作用是不可逆的，因此基於對脲酶抑制來檢測汞離子的傳感器在多次與抑制劑接觸后，很難使用再生溶液將脲酶的活性完全恢復，有必要研究一種可更新的脲酶傳感器。Soil microbial biomass carbon, microbial biomass nitrogen, soil basal respiration and metabolic quotient all showed a decreasing trend under more than 15 mg. kg - 1 cadmium or more than 200 mg. kg - 1 lead, respectively. soil dehydrogenase, urease and acid phosphotase activities have a significant decrease, and the activities of soil catalase and invertase taking sencond place, while soil protease activities showed stable state
隨重金屬濃度增加，各指標下降幅度各有差別，其中微生物生物量碳、微生物生物量氮以及基礎呼吸和微生物代謝商隨重金屬濃度增加而明顯下降；土壤脫氫酶、脲酶、酸性磷酸酶活性的下降幅度較為明顯，過氧化氫酶、蔗糖酶活性次之，蛋白酶活性較為穩定。
