Azo dyes represent a major class of synthetic colorants that are both mutagenic and carcinogenic (Waghmode et al., 2012). The most commonly used synthetic dyes in textile, food, papermaking and cosmetic industries are azo dyes (Kamel, R.H, 2011). As a consequence, there is an increase of environmental contamination caused by the large amount of dyes involved in the textile process that are discharged in the liquid effluents (Torralba 2009). Proces efficiency for Remazol Red RR, Remazol Yellow FG and Remazol Brilliant Blue were : 11,520 24,412.5 and 8,820 kJ/mmol, respectively INTRODUCTIONĭuring manufacturing and processing in the textile industry there are a large quantities of dyes used lost to the effluents (Akyol, et.al 2004). Air injection was increased a percentage of decolorization Remazol Red RR up to 46.7% in 180 min. The objective of this study was to investigate decolorization process of the textile dyes Remazol Red RR, Remazol Yellow FG and Remazol Brilliant Violet with an air injection using CGDE method. The observed pronounced effects of Manuka honey against planktonic bacteria but not within biofilm can be attributed to methylglyoxal as the characteristic antimicrobial component.Contact Glow Discharged Electrolysis (CGDE) is a plasma electrolysis methode has proved to treat organic wastewater effectively. CONCLUSIONS: Honey acts antibacterial against P. Neither a total prevention of biofilm formation nor a complete eradication of a 42 h-old biofilm by any of the tested compounds and the honeys were found. gingivalis biofilms and reduced the numbers of viable bacteria within 42 h-old biofilms. 10% of both types of honey inhibited the formation of P. MICs for hydrogen peroxide were 10 mg/l - 100 mg/l, for methylglyoxal 5 - 20 mg/l, and for propolis 20 mg/l - 200 mg/l. The amount of methylglyoxal was found to be 2 mg/kg in the domestic honey and 982 mg/kg in the Manuka honey. Manuka honey contained 1.87 mg/kg hydrogen peroxide and the domestic honey 3.74 mg/kg. gingivalis, the respective MIC50 of the German beekeeper honey was 5%. RESULTS: 2% of Manuka honey inhibited the growth of 50% of the planktonic P. gingivalis strains in planktonic growth and in a single-species biofilm. These components (up to 100 mg/l), propolis (up to 200 mg/l) as well as the two honeys (up to 10% w/v) were tested against four P. Contents of methylglyoxal and hydrogen peroxide as the potential antimicrobial compounds were determined. As a screening, MICs of the honeys against 20 P.
METHODS: One Manuka and one domestic beekeeper honey have been selected for the study. The in-vitro study was aimed to determine the antimicrobial efficacy against Porphyromonas gingivalis as a major periodontopathogen.
It might be also an alternative to the commonly used antimicrobials in periodontitis treatment. Conclusion: Anti-microbial properties of honey solution as mouth-rinse did not show any inhibition effect on plaque formation until day 4.īACKGROUND: Honey has been discussed as a therapeutic option in wound healing since ancient time. The fact that the probability value from day 1 (0.766) were gradually decreased to day 4 (0.076). results: There were significant increases of plaque index within each group, but no differences between all three groups in every experimental day. Group I rinse with 5% honey solution, group II with 25%, and group III with aquadest as control. Method: After a thorough prophylaxis, during 4 days period of no oral hygiene all subjects were rinsed with 10 ml mouth-rinse they received 3 times a day after meal. Purpose: To compare the efficacy of 5% and 25% honey solution and aquadest as mouth-rinses to control dental plaque during 4 days period. Honey is a traditional topical treatment for infected wounds and have inhibitory effect to around 60 species of bacteria including aerobes and anaerobes, gram-positives and gram-negatives. Some chemically active substances have been studied as an adjunct to mechanical plaque control.
Abstract Background: Periodontal care is an important step of periodontal health management.
