The purpose of this in vitro study was to determine whether adding silver-zeolite (SZ) to mineral trioxide aggregate (MTA) would enhance the antimicrobial activity of MTA against Staphylococcus aureus (ATCC #25923), Enterococcus faecalis (ATCC #29212), Escherichia coli (ATCC#25922), Pseudomonas aeruginosa (ATCC #27853), Candida albicans (ATCC #90028), Porphyromonas gingivalis (ATCC #33277), Actinomyces israelii (ATCC #12102), and Prevotella intermedia (ATCC# 15032). SZ was added at 0.2% and 2% mass fraction concentration to MTA powder. The control group was MTA powder with no SZ. The antimicrobial effect test was accomplished by placing freshly mixed MTA specimens on agar plates inoculated with microorganisms and comparing the zones of inhibition at 24, 48, and 72 h. The amounts of silver ion release from MTA specimens were measured with atomic absorption spectrophotometry at 10-min, 24-, 48-, and 72-h periods. The pH of MTA specimens was measured with a pH meter at 10-min, 24-, 48-, and 72-h periods. MTA with 2% and 0.2% SZ specimens showed inhibitory effects on some microorganisms at all time periods, whereas no antimicrobial activity showed for P. intermedia and A. israelii. MTA without SZ inhibited C. albicans, E. Coli, and P. intermedia. The highest silver release was detected in 2% SZ MTA at 24 h. The incorporation of SZ may enhance the antimicrobial activity of MTA.

Antibacterial Effect of Silver-Zeolite Containing Root-Canal Filling Material
ÇINAR, ÇAĞDAŞ; Ulusu, Tezer; ÖZÇELİK, BERRİN; Karamuftuoglu, Nevra; Yücel, Hayrettin (2009-08-01)
The aim of this study was to determine the in vitro antibacterial effect of two experimental glass ionomer cements (GICs) on Streptococcus milleri, Staphylococcus aureus, and Enterococcus faecalis after 24 and 48 h incubation by using the agar diffusion inhibitory test. Silver zeolite (SZ) was added at 0.2 and 2% mass fraction concentration to GIC (Endion). The control group was Endion with no SZ. Each of them were prepared to uniform size using a custom-made Teflon mold, and the GIC materials were prepared...
Synthesis, characterization and electrochromic properties of conducting copolymers of 3-[(3-thienylcarbonyl)oxy]-2,2-bis{[(3-thienylcarbonyl)oxy]}propyl 3-thiophene carboxylate with thiophene and pyrrole
Bulut, U; Yilmaz, F; Yagci, Y; Toppare, Levent Kamil (Elsevier BV, 2004-01-01)
3-[(3-Thienylcarbonyl)oxy]-2,2-bis{[(3-thienylcarbonyl)oxy]}propyl 3-thiophene carboxylate (TOTPT) was synthesized by the reaction of 3-thionylcarbonyl chloride with pentaerythritol, it was electrochemically polymerized with either thiophene or pyrrole by using tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte in acetonitrile (AN). Characterization of the resulting copolymers was carried out by FTIR spectroscopy, cyclic voltammetry, thermal gravimetry analysis (TGA), differential sc...
Evaluation of Staphylococcus aureus DNA aptamer by enzyme-linked aptamer assay and isothermal titration calorimetry
BAYRAÇ, CEREN; Öktem, Hüseyin Avni (2017-02-01)
To monitor the specificity of Staphylococcus aureus aptamer (SA-31) against its target cell, we used enzyme-linked aptamer assay. In the presence of target cell, horseradish peroxidase-conjugated streptavidin bound to biotin-labeled SA-31 showed specific binding to S aureus among 3 different bacteria with limit of detection of 103 colony-forming unit per milliliter. The apparent K-a was 1.39 mu M-1 +/- 0.3 mu M-1. The binding of SA-31 to membrane proteins extracted from cell surface was characterized using ...
High hydrostatic pressure induced inactivation kinetics of e. coli o157:h7 and s. aureus in carrot juice and analysis of cell volume change
Pilavtepe, Mutlu; Alpas, Hami; Department of Food Engineering (2007)
The main objective of this study was to determine the pressure induced inactivation mechanism of pressure-resistant Escherichia coli O157:H7 933 and Staphylococcus aureus 485 in a low acid food. Firstly, inactivation curves of pathogens were obtained at 200 to 400 MPa at 40ºC in peptone water and carrot juice. First-order and Weibull models were fitted and Weibull model described the inactivation curves of both pathogens more accurately than first-order model, revealing that food systems could exhibit eithe...
Medium optimization for cephamycin c overproduction and comparison of antibiotic production by ask, hom, and ask+hom recombinants of streptomyces clavuligerus
Ünsaldı, Eser; Özcengiz, Gülay; Department of Biology (2010)
Streptomyces clavuligerus is well-known for synthesizing several β-lactam antibiotics like cephamycin C which is produced through aspartic acid pathway initiated by aspartokinase (Ask) enzyme encoded by ask. Four different strains were constructed in our laboratory to increase cephamycin C production by S. clavuligerus. TB3585 and BA39 contained extra copies of ask gene on a multicopy plasmid, control strains TBV and BAV contained vector only in wild type strain NRRL3585 and hom-minus background, AK39, resp...
