Can the Ames test provide an insight into nano-object mutagenicity? Investigating the interaction between nano-objects and bacteria [PDF]
, 2012 The aim of this study was to assess the interaction of a series of well characterised nano-objects with the Gram negative bacterium Salmonella typhimurium, and how such an interaction may relate to the potential mutagenicity of nano-objects. Transmission

Interactions of sediment contaminants in the testing of mutagenicity [PDF]
, 1994 The influence of sediment contaminants on the Salmonella mutagenicity test was investigated to develop a preparation method not subject to interference by coexisting substances. Organic chemicals were extracted from sediment by dichloromethane/ethanol (4:

The Canadian Journal of Chemical Engineering, EarlyView.Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,
