many different plant species synthesize triterpenoid saponins as part of their normal programme of growth and development. examples include plants that are exploited as sources of drugs. interest in these molecules stems from their medicinal properties, antimicrobial activity, and their likely role as determinants of plant disease resistance. daisy (bellis perennis l.) accumulates triterpenoid ...

Improving soil microbial activity and using symbiosis and synergistic relations between plant growth-promoting rhizobacteria (PGPR), arbuscular mycorrhizal fungi (AMF) and plants through improving nutrient uptake can cause better growth of plants especially at salinity tension condition. To investigate the effect of AMF and PGPR application on growth and some nutrient uptake by corn in differen...

Background: Perovskia abrotanoides is small kind of lamiaceae family that find in iran and some neighboring countries by endemic. Objective: Because The effect of anti-bacterial and anti-fungal medical plant extract on bacteria and fungi and determine the Minimal Inhibitory Concentration (MIC) has not been done so present study follow the above aim. Methodes: In this study by using 80% methan...

Acipenser stellatus is one of the most invaluable species of Sturgeon fishes in the world. The purpose of this study was to identify the resident microbial community from the gastrointestinal tract (GIT) of Acipenser stellatus. One hundred and twenty three fungi were isolated from the GIT of 7 Acipenser stellatus samples including Aspergillus spp (45.5%), Trichoderma spp (8.9%) and Cladophialop...

Background and Aims: Since impression materials usually contact with saliva, blood, and oral soft tissues, their microbial contamination are harmful in immunocompromised patients. The aim of the present study was to determine the bacterial and fungal contamination in common impression materials. Materials and Methods: In current lab trial study, 5 different samples from each 4 impression mater...

Bacterial biofilm formation on fungi participates in the synergistic degradation of substrates, antagonism of fungal growth, bacterial utilization of fungi as nutrient sources, and the formation of more complex synergistic associations for the purposes of nutrient acquisition. While bacterial biofilm formation has been described in many systems, the molecular mechanisms that govern these intera...
