The Sensitivity of Resting Eggs of the Cladoceran Moina macrocopa to the Effect of Ionizing Radiation during the Reactivation of the Eggs

Abstract

We investigated the sensitivity of resting eggs of the cladoceran Moina macrocopa to the effect of ionizing radiation during the reactivation of the eggs. The study showed that the resting eggs during reactivation are more vulnerable to irradiation than the resting eggs in a stage of deep dormancy. The decrease in the efficiency of egg reactivation was observed at high doses, the growth rate of juveniles, fecundity, and the number of produced clutches by females strongly decreased when resting eggs at the reactivation stage absorbed doses of 64 Gy and higher.

Effects of electron‐beam irradiation on inoculated Listeria innocua, microbiological and physicochemical quality of fresh noodles during refrigerated storage

“…These results were in agreement with those obtained by Mahmoud () who found that L. monocytogenes was able to recover and grow in smoked salmon treated with irradiation at less than 2.0 kGy during storage at refrigerated temperature, which could result in a high risk of listeriosis disease (Sudha, Lammerding, & Griffiths, ). Low dose of EBI treatment could cause temporary dormancy of the microbial cells with the direct and/or indirect effects (Lopatina, Zadereev, Oskina, & Petrichenkov, ; Selim, Saha, & Mukherjea, ). Therefore, the surviving cells could trigger the DNA repair systems for self‐healing (Repar et al, ).…”
