By-products and surpluses from food industries could generate peptides with great interest for food formulation. Hence, the separation and concentration of bioactive peptides from natural sources becomes increasingly attractive to the food industry [1]. Recently, a snow crab byproducts hydrolysate showed antibacterial activity [2]. This activity was due to an antibacterial peptide of about 800 ...

in this study bactericidal activity of a malodor neutralizer containing silver nanoparticles manufactured in iran has been tested. for this purpose different concentrations of the product encounter with staphylococcus aureus, pseudomonas aeruginosa and bacillus cereus then the activity were evaluated in different contact times. the products containing at least 200 ppm of silver nanoparticles we...

Due to the inexorable invasion of our hospitals and communities by drug-resistant bacteria, there is a pressing need for novel antibacterial agents. Here we report the development of a sensitive and robust but low-tech and inexpensive high-throughput metabolic screen for novel antibiotics. This screen is based on a colorimetric assay of pH that identifies inhibitors of bacterial sugar fermentat...

White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. Long-lasting antibacterial properties of orthodontic cements can reduce this phenomenon. The aim of this research was to compare antimicrobial activity of three commercial glass ionomer cements with three commercial zinc phosphate cements, over time, against streptococcus mutans and candida albicans. Dir...

Drug resistance of bacterial pathogens is a growing problem that can be addressed through the discovery of compounds with novel mechanisms of antibacterial activity. Natural products, including plant phenolic compounds, are one source of diverse chemical structures that could inhibit bacteria through novel mechanisms. However, evaluating novel antibacterial mechanisms of action can be difficult...

BACKGROUND Currently, there is a wide range of products for mouth washing on the Polish market. They have different qualitative and quantitative compositions, and they differ particularly in the concentration of active substances. In antisepsis and disinfection, the significant reduction in number of cells of microorganisms in a particular environment is very crucial. The chemical agents should...

This review presents the biological activity-antibacterial, antifungal, anti-parasitic, antiviral, antitumor, antiinflammatory, antioxidant, and enzymatic activity-of halogenated marine natural products discovered in the past five years. Newly discovered examples that do not report biological activity are not included.

Antibacterial property for the plastic products is very important due to their wide spread usage in many areas close to human health such as a child toy or a food package. There are some methods to make polymers antibacterial such as ionizing radiation but they can be still infected by micro organisms during usage of them. The best and easy way to obtain antibacterial polymers is melt mixing of...
