Fe (Ⅱ) EDTA-NO highly effective return to original state germ characteristic research
Abstract: This article has used the complexing absorption union biotransformation method, The chemical absorption - biology reducing process two methods unifies in together, Through complexing absorbent function, Enable NO to change over to the liquid phase from the gas phase, Then returns to original state under microorganism's function it into the nitrogen, Uses both superiority to enable its flaw fully supplementary. Returned to original state the NO complexing absorption solution characteristic in the constant temperature table to the microorganism to conduct the research.
Experimental result proof: Different density glucose、Fe(Ⅱ)EDTA-NO、Fe(Ⅲ)EDTA and NH4+ to DN-3 fungus return to original state complex compound Fe(Ⅱ)EDTA-NO The EDTA-NO ability and grows influential. Along with Fe(Ⅱ)EDTA-NO density rise, The bacterium drops after its return to original state fast lead rise, Period achieves a maximum ratio return to original state speed. Joins certain density the ammonium chloride to be able to enhance Fe(Ⅱ)EDTA-NO EDTA-NO return to original state speed, But the return to original state speed grows is not remarkable. In under sur- few suitable carbon source condition, May realize the complexing absorbent unceasing circulation use. Finally appraises the mold mushroom spawn, Appraisal result DN-3 fungus ownership for intestines pole bacteria's in sewer intestines bacillus (Enterobacter cloacae).
Key word: Complexing absorption; Biological return to original state;Bacterium separation;appraises the mold bacterium
