Antimicrobial activity of 2-(2-hydroxyphenyl)-5-R5-1H-benzimidazoles, 2-(2-hydroxy-5-R5′-phenyl)-1H-benzimidazoles and their FeIII, CuII, AgI, ZnII and HgII nitrate complexes was tested towardStaphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella typhi, Shigella flexneri, andProteus(More)
Thirty-four thiosemicarbazones andS-alkyl thiosemicarbazones, and some of their ZnII and PdII complexes were obtained and purified to investigate antimicrobial activity. MIC values of the compounds were determined by the disc diffusion method againstEscherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhi,(More)
2-(2-Pyridinyl)-(L I ), 2-(6-methyl-2-pyridinyl)-(L II ), 2-(6-methyl-2-pyridinyl)-5-methyl-(L III ), 2-(3-pyridinyl)- (L IV ), 2-(3-pyridinyl)-5-methyl-1H-benzimidazoles (L V ) and their complexes with Fe(NO3)3, Cu(NO3)2, Zn(NO3)2, and AgNO3 were synthesized and antibacterial activity of the compounds was tested towardStaphylococcus aureus, Staphylococcus(More)
1,2-Bis-[2-(5-H/Me/Cl/NO2)-1H-benzimidazolyl]-1,2-ethanediols (L 1–L 4), 1,4-Bis-[2-(5-H/Me/Cl)-1H-benzimidazolyl]-1,2,3,4-butanetetraols (L 5–L 7) and their complexes with FeCl3, CuCl2, and AgNO3 were synthesized; antibacterial activity of the compounds was determined towardStaphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Klebsiella(More)
The biodegradation of wattle tannin was tested with six strains of yeasts isolated from decaying bark samples. The degradation of the condensed tannin was assayed in flasks and 2-liter jar fermentor by analysis of the residual leucoanthocyanin and flavanol groups after incubation during seven days. A strain of Candida guilliermondii (Y11) degraded rapidly(More)
In this study, microbial content and preservative efficacy of various cosmetic products, which are produced and sold in markets of our country, were investigated. Microbial content and preservative efficacies of products were investigated according to United States Pharmacopeia (USP) method. Microorganism counts of out 14 of 93 cosmetic products were(More)
The metal complexes of nine 2-substituted-1H-benzimidazoles (I-IX) with Ni(II), Pd(II), Cu(II), Ag(I), Zn(II) salts were synthesized. The compounds were characterized by melting point, analytical data, IR spectroscopy and magnetic susceptibility. The antimicrobial activity of the compounds was determined by the disk diffusion method in Mueller-Hinton Agar(More)
1,2-Bis-[2-(5-H/Me/Cl/NO2)-1H-benzimidazolyl]-1,2-ethanediols (L 1–L 4), 1,4-bis-[2-(5-H/Me/Cl)-1H-benzimidazolyl]-1,2,3,4-butanetetraols (L 5–L 7) and their complexes with ZnCl2, CdCl2 and HgCl2 were synthesized and antibacterial activity of the compounds was tested towardStaphylococcus aureus, S. epidermidis, Escherichia coli, Klebsiella pneumoniae,(More)
