Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

Abstract.
 
 Multidrug resistance is still a major health problem worldwide. Biofilm formation was related to the of bacteria mechanism. Acinetobacter baumannii, one that cause nosocomial infections, given particular attention due its high prevalence resistance. The current study address observing antibacterial activity and antibiofilm Curcuma domestica rhizome extract against multidr...

Antimicrobial photodynamic inactivation is considered a promising antimicrobial approach that may not develop resistance in the near future. Here, we investigate influence of photosensitizer chlorophyllin (CHL) and cationic permeabilizer polyethylenimine (PEI), exposed to red light-emitting diode, on human pathogen Pseudomonas aeruginosa free-living planktonic cells, sessile biofilm persister c...

Candida is an opportunistic pathogen and a common cause of fungal infections worldwide. Anti-fungal use against has resulted in the appearance resistant strains. The limited choice anti-fungal therapy means alternative strategies are needed to control infectious diseases. aim this study was evaluate inhibition biofilm formation by Hedera rhombea (Korean name: songak) extract. Biofilm assessed u...

In previous work, we described a protocol for measuring biofilm formation on opaque and non-opaque surfaces using reflected light. In the present work, we used the reflectance assay to assess biofilm formation for 14 strains of Enterococcus and compared our results with those obtained using a Crystal Violet (CV) assay. In general, the results for the two assays were in agreement: both identifie...

To distinguish Branhamella catarrhalis from Neisseria species a study of 140 strains was made on simple laboratory media, with particular reference to deoxyribonuclease (DNase) production, superoxol reaction, and growth characteristics. All 97 clinical isolates of B catarrhalis (58 of which were beta-lactamase positive) and eight strains of B catarrhalis from the National Collection of Type Cul...

Phosphate analyses are fundamental to a broad range of biochemical applications involving inorganic phosphate and organic phosphoesters such as phospholipids, phosphorylated proteins, and nucleic acids. A practical automated method utilizing robotics is described in this report. Five colorimetric methods of phosphate analyses based on formation of a phosphomolybdate complex and compatible with ...

Objective: Presently, one of the most common oral diseases is dental caries, which a biofilm-mediated disease. Lawsone methyl ether (LME) has shown promising antibacterial activity due to its 1,4-napthoquinone structure. Recently, 1,2,3-triazole scaffold been used in structural modification potential antimicrobial agents. To develop novel anticaries agents, structure with N-substituted 1,2,3-tr...

Marine resources such as marine invertebrates and mangrove plants favor the production of secondary metabolites that exhibit antifouling properties. These natural-derived compounds are considered environmentally friendly compared to synthetic with similar activity technological applications. The current study was conducted determine properties Diadema setosum (DS) Sonneratia lanceolata (SL) cru...

Alginate-gelatin mixed gel was applied to immobilized laccase for decolorization of some synthetic dyes including crystal violet. The immobilization procedure was accomplished by adding alginate to a gelatin solution containing the enzyme and the subsequent dropwise addition of the mixture into a stirred CaCl(2) solution. The obtained data showed that both immobilized and free enzymes acted opt...
