The present paper provides results of a study on heterotrophic bacteria occurrence and quantity in the biofilm and subsurface water of lake Jeziorak Maty. Degradation of several polycyclic aromatic hydrocarbons (PAH's) (anthracene, naphthalene) by neustonic and planktonic bacteria have been examined. It has been discovered that some aromatic hydrocarbons were better decomposed by neustonic bact...

UNLABELLED Rhodopseudomonas palustris is an alphaproteobacterium that has served as a model organism for studies of photophosphorylation, regulation of nitrogen fixation, production of hydrogen as a biofuel, and anaerobic degradation of aromatic compounds. This bacterium is able to transition between anaerobic photoautotrophic growth, anaerobic photoheterotrophic growth, and aerobic heterotroph...

The diversity and function of aerobic heterotrophic bacteria (AHB) in cyanobacterial mats have been largely overlooked. We used culture-dependent and molecular techniques to explore the species diversity, degradative capacities and functional guilds of AHB in the photic layer (2mm) of an oil-polluted microbial mat from Saudi Arabia. Enrichment isolation was carried out at different salinities (...

Experimental works are devoted to research the efficiency of deamonization and de-nitrogenation wastewater during treatment in a biodisk installation. Working hypothesis - immobilization microbiocenosis can provide simultaneous deep from organic compounds inorganic nitrogen-containing compounds. The purpose this work is assess purification highly concentrated pollutants mineralized nitrogen ins...
