Stability and morphological and molecular-genetic identification of algae in buried soils

Resumo

Living cultural strains of the green algae ‘Chlorella’ mirabilis and Muriella terrestris have been isolated from buried soils, and their identification has been confirmed by morphological and molecular-genetic analysis. It has been shown that the retention of their viability could be related to their small size and the presence of sporopollenin in cell walls. The effect of methods for the reactivation of dormant microbial forms on the growth of algae in paleosols has been estimated. The total DNA content has been determined in buried and recent background soils, and relationship between DNA and the presence and age of burial has been established.
