The microorganisms intended for use as probiotics in aquaculture should exert antimicrobial activity and be regarded as safe not only for the aquatic hosts but also for their surrounding environments and humans. The objective of this work was to investigate the antimicrobial/bacteriocin activity against...
We have investigated the antiradical activity of ethanolic extract of mengkudu leaves ( Morinda citrifolia L. ) and brotowali stem ( Tinospora crispa L. ) using radical scavenging assay or DPPH radical. Thin layer chromatograms were also... T Irianti,A Puspitasari,L Machwiyyah,... - 《Cur...
Silver nanoparticles were obtained in the cellulose matrix with an average size of 140 nm and with antimicrobial activity against both sensitive and resistant Gram positive (using 1500 ppm) as well as sensitive and resistant Gram negative (using 125 ppm) bacteria. Also, an inverted disk-...
In this paper,the effect of objective factors to the antimicrobial activity of chitosan have been studied,in purpose to confirm the best conditions.St.aureus was used as experimental microbial and inoculated to broth substrate with certain chitosan.The effects of the acetic concentration,enviroment pH...
(6.58 mm) was the largest area of growth inhibition demonstrated in this research. Activity against Gram+ bacteria was also shown for evening primrose extract—stronger (6.35 mm) againstEnterococcus faecalisand weaker (4.45 mm) againstEnterococcus hirae. Effective growth inhibition ofE. faecalis, ...
In this study, the ethanol extract (EE), ethyl acetate extract (EAE), aqueous decoction extract (ADE) and aqueous maceration extract (AME) of Vernonia amygdalina leaves were subjected to total phenolic (TP) and total saponin (TS) content determination, in vitro radical scavenging activity and ...
Studies have been done to demonstrate the antimicrobial activity of IONP30,31,32, still the mechanism behind antimicrobial activity is a matter of intensive research, in present. Chatterjeeet al.32has demonstrated that IONP has antimicrobial activity againstE. coliand the activity increases with incr...
摘要: Extracts of the bark, leaves, root and stem of Ximenia americana were tested for their antimicrobial and antifungal activity.关键词: Ximenia americana Antimicrobial activity DOI: 10.1016/S0367-326X(02)00302-7 被引量: 78 年份: 2003 ...
the research effort on bimetallic nanoparticles have been received significant attractive attention, owing to its high catalytic activity and better durability than that of mono metals. To the best of the author’s knowledge, there are no reports on the development of rGO-PANI supported mono (Pd)...
The methods discussed in this paper can be used for comparing the bactericidal and fungicidal activity of nanoparticles when conducting research, it can find application in production control, and data on antimicrobial activity can be applied for the development of promising preservatives and drugs. ...
