Metabolic Capabilities Of Sulfur Oxidizing Bacteria And Their Role In Water Pollution, M. I. H. Aleem
Metabolic Capabilities Of Sulfur Oxidizing Bacteria And Their Role In Water Pollution, M. I. H. Aleem
KWRRI Research Reports
This report describes investigations into the physiology of microorganisms that are commonly involved in the oxidation of inorganic sulfur compounds. The metabolic activities of these bacteria play a potent role in several fields of economic importance such as strip mining operations, water pollution, corrosion, metallurgy, petroleum technology and soil fertility processes.
The oxidation of inorganic sulfur compounds was studied in the chemolithotrophs Thiobacillus denitrificans, Thiobacillus A2, Thiobacillus neapolitanus, and a photolithotroph Rhodopseudomonas palustris. Cell suspensions from all of the thiobacilli catalyzed completely the oxidation of sulfide, thiosulfate, and sulfite to sulfate. The oxidation of thiosulfate in R. palustris …
The Lasting Antimicrobial Qualities Of Three Root Canal Sealing Materials : Grossman's Sealer, Rickert's Sealer, And N2 Permanent, Lee R. Ingersoll
The Lasting Antimicrobial Qualities Of Three Root Canal Sealing Materials : Grossman's Sealer, Rickert's Sealer, And N2 Permanent, Lee R. Ingersoll
Loma Linda University Electronic Theses, Dissertations & Projects
An in vitro study using polyethylene tubes filled with Grossman's sealer, Rickert's sealer, and N2 permanent was conducted over a six month period in an effort to determine their lasting antimicrobial properties against eight different microorganisms.
From the study it was observed that N2 permanent possesses a long-lasting antimicrobial effect, but this effect appears to diminish greatly with time. Further investigation is needed to determine whether or not the effect is actually permanent in nature. The N2 permanent was also shown to have broader antimicrobial effectiveness against the eight microorganisms tested. N2 permanent produced zones of inhibition against five of …
