It was found that quinoxaline- 2‚ 3-dione -6-sulphonyl benzimidazole (s) have pronounced effect as compared to plain quinoxaline -2‚3-dione against worms‚ the gram positive and gram negative bacteria. Among all the compounds‚ 2‚ 3-dioxo -1‚ 2‚ 3‚ 4-tetrahydroquinoxaline-6-sulphonyl (2-acetyl) benzimidazole have been exhibited good activity in the dose of 20 mg/ml against earth worm‚ bacteria and fungi like standard drug

The effect of environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH on microbial growth and survival Abstract: Microbial growth can be affected by different environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH. Six experiments were carried out in this report testing for microbial growth against different environmental factors. Good aseptic techniques were used to prevent contamination‚ resulting in a uniform set of results

Antibacterial action of the irrigants against Enterococcus faecalis in the root canal The overall percentage reduction of E. faecalis inside the root canal after biomechanical procedures was presented in table1. All the irrigants significantly reduced bacteria in comparison with positive control group (P< 0.01). The average reduction of bacteria in the presence of E.galbie did not have any significant difference with 2.5% NaOCl‚ CHX 2%‚ CHX 0.2% and M.communis L. (P > 0.05). The average reduction
