A novel methanotrophic co-metabolic system with high soluble methane monooxygenase activity to biodegrade refractory organics in pulping wastewater.
Bioresource Technology 2018 May
Pulping wastewater still contains massive refractory organics after biotreatment, with high colority, low biodegradability, and lasting biotoxicity. To eliminate refractory organics in pulping wastewater, a methanotrophic co-metabolic system in a gas cycle Sequencing Batch Biofilm Reactor (gcSBBR) seeded by soil at a ventilation opening of coal mine was quickly built on the 92nd day. The removal rate of COD, colority and TOC was 53.28%, 50.59% and 51.60%, respectively. Analysis of 3D-EEM indicated that glycolated protein-like, melanoidin-like or lignocellulose-like, and humic acid-like decreased by 7.85%, 5.02% and 1.74%, respectively. Moreover, this system exhibited high activity of soluble methane monooxygenase (sMMO) and mmoX encoding sMMO reached up to 7.89 × 105 copies/μL. Methanotrophs, namely, Methylocaldum (8.28%), Methylococcus (6.06%) and Methylomonas (0.07%), were detected by 16S rRNA sequencing. And other bacteria were dominated by Denitratisoma, Anaerolineaceae_uncultured and Methylophilaceae_uncultured. Refractory organics was biodegraded through the synergy among microorganisms, and a postulated synergy pathway was put forward.
