“…Microbial mutagenicity tests can of distinguish rapidly the mu-tagenic activity of many materials, including plant extracts, phenolics, and glycoalkaloids (van der Hoeven et al, 1983;Ness et al, 1984;Fung et al, 1988;Soudamini et al, 1995;Patrinelli et al, 1996). Many chemicals that elicit a mutagenic response in the Salmonella-E. coli microsome assay have been shown potentially to be mutagenic and carcinogenic to humans and laboratory animals (Mc-Cann et al, 1975;McCann and Ames, 1976).…”

Freeze-dried water extract of potato peels (pp), containing chlorogenic, caffeic, gallic, and protocatechuic acids, was tested for effectiveness as a natural antioxidant. The pp was prepared from peel waste of Russet Burbank potatoes. Safety concerns regarding the use of pp in foods were investigated. The pp was examined for mutagenic activity using the in vitro Salmonella typhimurium-Escherichia coli microsome assay and found to be nonmutagenic. Plate count of pp revealed <10 CFU/g. The antibacterial activity of the pp was species dependent. It was effective only at high concentration against gram negative and one gram positive bacteria but it was bacteriostatic.

“…The decrease in mutagenic potency in TA98 and TA2637 implies inhibition of microsomal fraction by an antimutagen. In studies with rhubarb extracts, Van der Hoeven et al (1983) were able to assign emodin as the active component in strain TA1537, a nonplasmid parent strain ofTA2637 (Marón and Ames, 1983). However, we were not able to give a similar assignment due to the complex nature of sicklepod extract mutagenicity data.…”

Investigation of Competitive and Noncompetitive Adsorption of Some Heavy Metals Ions on Leucodon sciuroides (Hedw.) Schwägr

et al. 2020

Heavy metals are an important pollutant group. Adsorption is one of the methods used to remove heavy metals from the environment. Mosses were preferred as bio-indicators because they have the capacity to accumulate many elements by their high surface-to-volume ratio. Leucodon sciuroides (Hedw.) Schwägr. (LS) are mosses that play an important part of the ecosystem and are collected from the Ida Mountain (Kazdag) region of Çanakkale (Turkey). For the purpose of determining the adsorption capacity of heavy metal ion (Pb2+, Cd2+, Co2+, Ni2+, Zn2+, and Cu2+) analysis conditions, pH, contact time, and adsorbent amounts were determined and the maximum adsorption capacity was calculated with the help of the relevant isotherms. Heavy metal concentrations were determined by inductively coupled plasma-mass spectrometry. It was determined that the optimum adsorption for mosses was 30 min at pH = 6.0 (the pH at which maximum adsorption occurs). The adsorption event shows that some divalent cations fit the Freundlich isotherm and some fit the Langmuir isotherm model. A pseudo-second-order reaction best fits the kinetic data for metal ions. Among the six metal ions studied, the highest adsorption was observed in Pb2+ and Cu2+ cations. According to the competitive adsorption results, the moss has a great advantage in determining the Pb2+ and Cu2+ cations industrially as well as other metals and in removing other metal impurities from the environment. Also, LS is exploited as a biosorbent to remove metal ions from aqueous solutions and can be used as a biomarker.
