a. calamus that grows in province of baluchistan and kerman in iran plays a major role in the revival of traditional medicine. despite the useful role of this plant in many ailments, its anti-bacterial properties are not well understood. in this study, we investigated anti-bacterial activities of rhizomes ware of a. calamus against various strains of bacteria such as staphylococcus aureus and e...

l-asparaginase has remarkable properties which make it useful in dual pharmaceutical and food industries.in this study, simple and advantageous method has been validated for rapid and precise determination of intracellular l-asparaginasein bacterial species. a suspension of bacterial cells was used instead ofcell extract and incubated by substrate (asparagine) after simple wash and centrifugati...

Nanomaterials are increasingly used to the targeting of gram-positive and gram-negative bacteria as an alternative to antibiotics. Bacterial infections are a major cause of chronic infections and mortality. People requirement for new materials for pathogenic bacteria treatment. It seems that nanomaterial-based strategies can be resolving this problem. In this research, improved antibacterial na...

the antimicrobial efficacy of methanol and water extracts of seeds of the plant swietenia macrophylla (family: meliaceae) was evaluated against selected pathogenic bacterial strains (bacillus cereus mtcc 430, klebsiella penumoniae mtcc 109, pseudomonas aeruginosa mtcc 424, escherichia  coli mtcc 443, staphylococcus aureus mtcc 96, salmonella typhimurium mtcc 98, micrococcus luteus mtcc 106) and...

This study examined the effect of dissolved organic matter (DOM) on ectoenzymatic activity, bacterial growth and community structure in the Hudson River. Our main approach was to mix bacterial communities and water from various locations in the Hudson River and its tributaries, and then to monitor bacterial activity and community structure determined by fluorescence in situ hybridization with o...

Nowadays silver nanoparticles (AgNPs) are used as antimicrobial due to its well known physical, chemical, and biological properties. A large collection of bacterial cells adhering to a surface is called bacterial biofilm. Exposure to silver nano particles (AgNPs) may prevent colonization of new bacteria onto the biofilm. In the present work, we have investigated whether the biofilm format...

Isolation of autochthonous bacteria from marine sources as a potential probiont in biocontroling against pathogenic Vibrio species in the shrimp culture industry was the aim of current research. A total of 198 bacterial strains were isolated from pond water, sediment, hepatopancreas and gut samples of shrimps after culturing the samples on Tryptic Soy Agar and incubated at 30 °C for 24-48 h. Th...
