Biodiversity of Plants Rhizosphere and Rhizoplane Bacteria in the Presence of Petroleum Hydrocarbons

Following plants-barley (Hordeum sativum), alfalfa
(Medicago sativa), grass mixture (red fescue-75%, long-term
ryegrass - 20% Kentucky bluegrass - 10%), oilseed rape (Brassica
napus biennis), resistant to growth in the contaminated soil with oil
content of 15.8 g / kg 25.9 g / kg soil were used. Analysis of the
population showed that the oil pollution reduces the number of
bacteria in the rhizosphere and rhizoplane of plants and enhances the
amount of spore-forming bacteria and saprotrophic micromycetes. It
was shown that regardless of the plant, dominance of Pseudomonas
and Bacillus genera bacteria was typical for the rhizosphere and
rhizoplane of plants. The frequency of bacteria of these genera was
more than 60%. Oil pollution changes the ratio of occurrence of
various types of bacteria in the rhizosphere and rhizoplane of plants.
Besides the Pseudomonas and Bacillus genera, in the presence of
hydrocarbons in the root zone of plants dominant and most typical
were the representatives of the Mycobacterium and Rhodococcus
genera. Together the number was between 62% to 72%.
