title: Effect of plant extract on the degradation of nitroaromatic compounds by soil microorganisms.
abstract: Remediation of soils contaminated by nitroaromatic compounds and nitramines, i.e. explosives, is known as very important, complicated, and rapidly developing area of biotechnology. A search for optimal growth conditions for soil bacteria is of a great importance in order to isolate various xenobiotic degraders. Bacteria consortium A43 was isolated from soils contaminated with explosives. In the presence of carbohydrate and plant extract, an addition of TNT to the solidified minimal medium stimulated the growth of the tested bacteria, as compared to other bacteria consortium isolated from the same soils. Reducing sugars as carbohydrates, and cabbage leaf extract as a plant extract were used in these experiments. Cultivation of the A43 in liquid medium of the same content showed that addition of cabbage leaf extract alone to medium is much more efficient for TNT degradation by growing biomass as compared to addition of carbohydrate alone.
