the genus rhodococcus is gram positive bacterium which was classified into the family of nocardiaceae. the organism can be isolates from different sources, with capability to degrade diverse types of pollutant. nowadays, scientists reported a few secondary metabolites which are produced by rhodococci. hence, the present study tried to isolate rhodococci from different soil samples with the capa...

the usage of antimicrobial materials for coating meat products, in addition to reducing the microbial population and increase of the quality safety of products, be greatly reduced usage of nitrites as preservatives and synthetic carcinogens. compounds that have antimicrobial activity can be mixed, stabilized or incorporated with edible coatings. spices and vegetable extracts are also a group of...

Natural antimicrobials are secondary metabolites that can be found in plants, animals, and microorganisms.Plants, especially herbs and spices, are been given more attention in natural antimicrobial research, however; this chapter focuses on the newly discoveries in fruits and vegetables. Microorganisms that are been used in food fermentation also produce different antimicrobial metabolites incl...

The efficiency of antibiotics in combating microbial infections was very promising shortly after their introduction. It was even thought that the microbial war was as good as over as was declared by the Surgeon General of the United States. However, resistance to these agents developed rapidly afterward and the problem of antibiotic resistance has remained a menace threatening the benefits of a...

To prevent and treat diseases caused by the spread of microbes, humans have invented all sorts of effective antimicrobial substances. The most widely used antimicrobial substance is antibiotics. However, misuse of antibiotics can generate various negative effects, bacterial resistance, decreased immunity, and internal flora imbalance which can lead to endogenous infection. In addition, existing...

Antimicrobial usage is common in Asian aquaculture. This study aimed to determine the quality of antimicrobial products used by Vietnamese striped catfish (Pangasianodon hypophthalmus) farmers. Twenty one antimicrobial products (11 products contained a single antimicrobial and 10 products contained a mixture of two different antimicrobials) commonly used by catfish farmers were obtained from so...

OBJECTIVES The aim of this study was to investigate the antimicrobial activity of a range of commercially available tea tree oil (TTO) products and to evaluate whether formulation plays a significant part in their antiseptic activity. METHODS The antimicrobial activity of the purchased products and control TTO solutions was assessed against Escherichia coli, Staphylococcus aureus, Salmonella ...

The use of and search for drugs and dietary supplements derived from plants have accelerated in recent years. Ethnopharmacologists, botanists, microbiologists, and natural-products chemists are combing the Earth for phytochemicals and "leads" which could be developed for treatment of infectious diseases. While 25 to 50% of current pharmaceuticals are derived from plants, none are used as antimi...

Researches concerning the development of polymer biocides represent a great challenge for both academic world and industry. This review will cover most recent advances in antimicrobial polymers for textile coating and finishing. Methods of synthesis, application and grafting of such polymers on textile substrates will be illustrated. Biocidal performances and stability (i.e. fastness to washing...
