Reduction products of chlorinated hydrocarbons are different if they with different reductive system, for example, the main products of HCA are PCE, TCE, trans-DCE and cis-DCE with Ag/Fe system, but that is ethane with Pd/Fe system.
and reduce NO-2-N and NO-3-N into NH3-N with organic carbon source and adequate concentration of NO-2-N and NO-3-N,while under anaerobic condition,strain dN13 could still reduce NO-2-N and NO-3-N into NH3-N with sodium acetate as the sole carbon source.
The main experimental results were as follows:Strain Escherichia coli FR-2 can reduce Fe(III)EDTA which formed in the system efficiently, Fe(II)EDTA-NO and Fe(II)EDTA in the absorption solution would inhibit the cell growth of FR-2 and the reduction of Fe(III)EDTA.
This is done by reducing the problem to the case of bipartite quivers of a special form and using a function DP on three matrices, which is a mixture of the determinant and two pfaffians.
The compound 12 was found to be five times more potent than 11 in reducing twitch response to nerve stimulations, indicating the importance of extended interonium distances and 17-acetoxy function for potent antagonist activity.
The multiple antioxidant activity of the polysaccharides was evidenced by significant reducing power, superoxide scavenging ability, inhibition of mice erythrocyte hemolysis mediated by peroxyl free radicals, and also ferrous ion chelating potency.
Niacin and chromium treatments had a protective effect on the intestine of the hyperlipidemic rats as well as a lipid-reducing effect.
The polycarboxylate superplasticizer, which had suitable graft and block polymers of polyethylene glycol or polyoxyethylene, and a suitable sulfonic group, had small slump loss besides high water-reducing performance.
