Abstract Inhibitory impact of Artemisia herba-alba extract on Klisinema persicum growth was investigated. This study looked at the effects different concentrations A. extracts and antioxidant enzyme (superoxide dismutase Catalase) activity K. in order to determine optimal dose range for good anti-algal action. Concentrations were used (2.5,5, 10, 20, 40,80 160) mg. L -1 as well control. Results...

Background: Water hyacinth is a plant that grows in freshwater, commonly found Indonesia. leaf extract contains antimicrobial bioactive components such as tannins, flavonoids, alkaloids, and terpenoids. Prevotella intermedia one of the bacteria cause periodontal disease. increases subgingival plaques patients with disease exacerbated by hormonal changes. Therefore, water may affect growth inter...

Stenotrophomonas maltophilia is an important nosocomial pathogen with intrinsic resistance to multiple antibiotics. Previous investigations have shown flavanols from black tea to possess antibacterial activity. This study describes the determination of minimum inhibitory concentrations and minimum bactericidal concentration for theaflavin independently and in formulations with the polyphenols e...

Previous studies had shown that sub-inhibitory concentrations of silver sulphadiazine (AgSD) stimulated the production of Toxic Shock Syndrome Toxin-1 in certain strains (responder strains) of Staphylococcus aureus and that protease production was also affected. No changes were detected in other strains (non-responders). Extracellular proteins from eleven responder and non-responder strains gro...

introduction: antibiotics have the potential to adversely affect the microbial community. for anaerobic digestion, a sufficient methanogenic population needs to be preserved in the system. the main aim of this study was determination of inhibitory concentration of oxytetracycline on methanogenic bacteria. methods: a 120 ml jacketed bioreactor with a 90 ml working volume was inoculated granular ...

the polyphenol silybin has anti-oxidant and anti-cancer properties. the poor bioavailability of some polyphenols (flavonoids, and terpenoids) can be improved by binding them to phosphatidylcholine (phytosome technology). many studies have focused on the most common phytosome, silybin-phosphatidylcholine, particularly for its hepatoprotective effects. however, in recent years, studies have also ...

  Biofilm of Pseudomonas aeruginosa, an opportunistic pathogen, can cause serious health problems, such as chronic infections, especially in immunocompromised patients. Many studies have suggested administration of new generation of antibiotics, as P. aeruginosa biofilms have developed high resistance to antimicrobial drugs. This study reports the inhibitory effect of three medicinal plant extr...

Sea cucumber is presented as potential marine source of antimicrobial compounds. The purpose of this study is to evaluate antifungal effects of sea cucumber, Holothuria leucospilota, extracts on Aspergillus niger and Candida albicans. Methanol and chloroform extracts of the body wall, gonad and intestine of sea cucumber, H. leucospilota, collected from Persian Gulf, were evaluated for their ant...

The susceptibilities of 12 strains of enterococci and 10 stains of Listeria monocytogenes to N-formimidoyl thienamycin were determined by a standard broth dilution method. Minimal inhibitory concentrations for L. monocytogenes strains were less than 0.25 micrograms/ml. As a group, strains of Streptococcus faecium were less susceptible than Streptococcus faecalis strains, but even for the latter...
