Radiation-induced effects on some common storage edible seeds in India infested with surface microflora

Effect of Heat Treatment and Gamma Irradiation on the Total Bacterial Count of Selected Millet Grains (Jowar, Bajra and Foxtail)

“…The fungal growth and their population on gamma treated rice was found to be decreased significantly (p<0.05) with the increasing irradiation dose and storage time. Immediately after irradiation, the depletion of fungal growth on rice was noticed at 2 kGy, whereas total inhibition was noticed at 3 kGy after one and half month (Maity et al, 2004).The interaction effect of treatment and grain revealed that significant variation among the grains and treatments. Maximum effect of treatment was observed in foxtail millet and a minimum effect in pearl millet.…”

“…However there is no significant difference is observed among the DHEI 2.5, WHEI 2.5, DHEI 1.0 and WHEI 1.0 (p>0.05). Maity et al, (2004) studied on the application of gamma irradiation up to 6 kGy (0.12 kGy/h) in rice (Oryza sativa) and pulse (Cicer arietinum) and they concluded that significant reduction in the fungal growth on these grains was noted at 1-2 kGy, while complete inhibition of the contaminating fungi was observed above 4 kGy. The fungal growth and their population on gamma treated rice was found to decreased significantly with increasing irradiation dose and storage time.…”

Biocidal Effect of Gamma Radiation on the Ecology of Filamentous Fungal Populations Associated with Stone Deterioration

“…There are some studies showing the effects of ionizing radiation on filamentous fungi [6,24,25]. However, few studies are associated with the preservation of cultural and geological heritage, making this work an innovative tool in this area.…”

“…Some species of Alternaria exhibit high resistance when exposed to higher doses than 4 kGy [24]. This fact led to the use of strains of A. alternata isolated from the radioisotope-contaminated environment around a Chernobyl nuclear reactor in Ukraine as a model for the genetic study of resistance to gamma radiation [31].…”

“…In relation to block A (Fig. 3), the following elements were detected: 6 C, 8 O, 12 Mg, 13 Al, 14 Si, 20 Ca, 24 Cr, 25 Mn and 26 Fe. The analysis of block B showed the same chemical components, except for the absence of manganese: 6 C, 8 O, 12 Mg, 13 Al, 14 Si, 20 Ca, 24 Cr and 26 Fe.…”
