From: Toxicity of iron oxide nanoparticles to grass litter decomposition in a sandy soil
Mean (n = 3) of heterotrophic cultivable colony forming units (105 cfu mL−1) of bacteria and fungi (A) and microbial biomass carbon (Cmic) and nitrogen (Nmic) (B) in control soil without any amendment (CS) as well as soil amended with grass litter (LS), and grass litter-nanoparticles (LNPS) after 90 and 180 days of incubation. Bars on panel denote the standard error (±1) of mean. Small letters indicate the significant differences among treatments and time for Bacteria as well as for Cmic, whereas capital letters indicate this difference for Fungi and Nmic, at probability level of 5%.
