The effect of soil modification on diesel fuel removal from soil in field conditions was studied. The experiment was established in the form of microplots. Diesel fuel was introduced into the soil at the concentration of 5% (ww. - in count on layer 15 cm depth of plot 1x1 m size). Particular experimental variants were modified by means of fertilization, stirring and inoculation with microorganisms...
The impact of long term application of pesticides for crops protection on bacteria and fungi resistance has been studied. At first the microbes have been isolated from two soil samples, namely a soil sample contaminated with pesticides, and a control one. Subsequently, under in vitro conditions with the same pesticides present, microbes growth capacities were observed. Growth capabilities of microorganisms...
W pracy przedstawiono wyniki badań, w których oceniano wpływ wybranych węglowodorów aromatycznych na biomasę żywych drobnoustrojów w dwóch, różnych typach gleb, z uwzględnieniem wielkości dawki użytego węglowodoru i czasu inkubacji. W doświadczeniu wykorzystano dwie gleby (piasek gliniasty lekki pylasty oraz glinę lekką pylastą). Próby glebowe o masie 300 g mieszano z wybranym węglowodorem: benzenem,...
The results of a study on the composition of microflora settling the pilot bio filter bed that purifies the exhausting gases from a cable factory's coil-wire varnishing division are presented in this study. The ability of isolated bacterial strains to biodegrade phenol was also evaluated using culture media of various compositions. Phenol was introduced into the medium at the following concentrations:...
Results of bioassays performed in Department of Microbiology and Environmental Biotechnology as well as statistical analysis point out to significant interdependence among decreasing amounts of diesel fuel in a soil and a germination level of spring barley (Ortega cv.) seeds, length of above ground parts of seedlings and their root system length. Calculated values of resistance indices (RI) express...
