New Nanoparticles Findings from Kasetsart University Reported (Shift of bacterial community structure in two Thai soil series affected by silver nanoparticles using ARISA)

By a News Reporter-Staff News Editor at Biotech Week -- Research findings on Nanoparticles are discussed in a new report. According to news reporting out of Bangkok, Thailand, by NewsRx editors, research stated, "In this study we examined the influence of silver nanoparticles (SNP) on the bacterial community and microbial processes in two soils from Thailand, a Ayutthaya (Ay) and Kamphaengsaen soil series (Ks). Results of this analysis revealed that SNP did not affect to pH, electrical conductivity, cation exchange capacity, and organic matter in both the Ay and Ks series."

Our news journalists obtained a quote from the research from Kasetsart University, "Automated ribosomal intergenic spacer analysis (ARISA) analysis profiles showed that bacterial community decreased with increasing SNP concentration. Pearson's correlation coefficient and multidimensional scaling analyses indicated that the effects of SNP on the bacterial community structure depended more on soil types than SNP application rates and incubation periods. Additionally, the results showed that SNP application rates affected on amount of CO2 emissions, while SNP application rates had no effect on N mineralization in both soil types. This study is the first investigation of the effects of SNP on bacterial community using ARISA analysis."

According to the news editors, the research concluded: "Our results might be useful to evaluate the risk associated with the applications of SNP for consumer products and agricultural practices."
