Potential of <i>Pseudomonas yamanorum</i> for the valorization of municipal biosolids

Abstract It is generally accepted that some trace organic contaminants (TrOCs) pass through the wastewater treatment process without being properly treated and find their way into waterbodies. These molecules can also be concentrated within biosolids (BS) adsorption. The presence of TrOCs in BS, which are then commonly used as soil amendments agriculture, may affect plant growth viability. potential risks posed by usually ignored because they present low concentrations mostly have relatively short half-lives. However, continuous addition these substances water sources on farmlands makes them pseudo-persistent. To reduce selected from Pseudomonas yamanorum LBUM636 (PY) was tested with a commercial bacterial blend Bacillus spp. (BC). About 60% removal atrazine achieved using PY-amended BS. Bioslurries inoculated PY had high laccase activity at about 2,200 U/L. Laccase seven times higher samples where BC present, suggests synergistic effect between PY. Concentrations phenazine-1-carboxylic acid, an antibiotic biopesticide effect, were important PY-inoculated bioslurries.
