Tugay T. Adaptation of micromycetes to chronic ionizing radiation

To study the behavioral adaptations of micromycetes that were formed under exposure of chronic ionizing radiation and possible mechanisms of its realization two model systems were created; one of them imitated the influence of "hot" particles, another - the radioactivity of the contaminated soil of the alienation zone ChAES. It was established that the adaptation of micromycetes to relatively high doses of radiation isn't a unique property of some species but there are frequent occurrences of the adaptive feature in a lot of taxons that formed under exposure of chronic radiation and it has the maximum rate in areas with radioactivity background up to 500 mRh-1. It was established that in all the studied micromycetes in oligocarbotrophic conditions radioadaptive properties correlate with the high efficiency of substrate utilization (2.0-3.5 times higher than that of the control strains).
