microflora of a corpse
decay
putrefaction
ammonification
time of death
The article summarizes data on microorganisms involved in the process of decomposition of a Sus scrofa domesticus L. carcass used as a model for studying biological characteristics of the mechanisms of decay. The results on the prevalence, abundance, and diversity of micromycetes and bacteria found in fragments of corpses and in the bed are presented. The potential of microorganisms’ usage, as well as application of the outcomes of microbial destruction of organic matter for evaluation of the time of death in the late post-mortal period are shown. In particular, it was revealed that the increase in the duration of decomposition leads to reduction of species diversity in bacterial communities with concomitant increase in the number of certain life forms.
