Exemplar Abstract for Pseudomonas sp. None 2015.

A Pseudomonas sp. 102 strain, which is highly resistant to toxic effects of cadmium and has plant growth-promoting activity, can significantly increase growth parameters and biomass of tomato plants, including those observed under toxic effects of cadmium. The greatest positive effect was observed in plants transformed with the bacterial adhesin gene rapA1, the product of which is important for colonization of plant roots by bacteria. It was also shown that shoots of transgenic tomato plants accumulated the greatest amount of cadmium during inoculation with Pseudomonas sp. 102. The ability to extract high concentrations of cadmium and accumulate a large biomass under stress opens up prospects for the further use of associative interactions between tomato and Pseudomonas for phytoremediation. phytoremediation, cadmium, tomato, Pseudomonas, inoculation, agglutinins, This study was carried out using the equipment of the Biomika Centre for Collective Use of the Institute of Biochemistry and Genetics (Ufa Federal Research Centre, Russian Academy of Sciences) as part of the government task (project no. AAAA-A16-1160203500284). This study was supported by the Russian Foundation for Basic Research (project nos. 18-34-20004 and 18-34-00033) and 18-344-0033 mol_a_ved and 34-00033 mol_a).

To show that an adsorbing biofilm carrier (GAC) can be advantageous for atrazine bioremediation over a non-adsorbing carrier, fluidized bed (FB) reactors were operated under atrazine limiting concentrations using Pseudomonas sp. strain ADP as the atrazine degrading bacteria. The following interrelated subjects were investigated: 1) atrazine adsorption to GAC under conditions of atrazine partial penetration in the biofilm, 2) differences in atrazine degradation rates and 3) stability of atrazine biodegradation under non-sterile anoxic conditions in the GAC reactor versus a reactor with a non-adsorbing biofilm carrier. Results from batch adsorption tests together with modeling best described the biofilm as patchy in nature with covered and non-biofilm covered areas. Under conditions of atrazine partial penetration in the biofilm, atrazine adsorption occurs in the non-covered areas and is consequently desorbed at the base of the biofilm substantially increasing the active biofilm surface area. The double flux of atrazine to the biofilm in the GAC reactor results in lower effluent atrazine concentrations as compared to a FB reactor with a non-adsorbing carrier. Moreover, under non-sterile denitrification conditions, atrazine degradation stability was found to be much higher (several months) using GAC as a biofilm carrier while non-adsorbing carrier reactors showed sharp deterioration within 30 days due to contamination of non-atrazine degrading bacteria.
