以明胶为包埋材料,戊二醛为交联剂固定化粪产碱菌所产的酸性脲酶。
Acid urease of Alcaligenes faecalis was immobilized onto the gelatin crosslinked with glutaraldehyde.
玉米收获后,土壤转化酶、脲酶均高于播前或与播前相当,而酸性磷酸酶活性则低于播前。
Urease and invertase activities were higher after harvest than before sowing, however acid phosphatase activity was lower after harvest.
在同样化肥水平上增施有机肥能增加脲酶、转化酶活性,而降低酸性磷酸酶活性;
With same application rate of chemical fertilizer, application of organic fertilizer could increase urease and invertase activities, but decrease acid phosphatase activity.
