This research included experiments on the advanced treatment of coking wastewater by electrochemical reactor. The results showed that a favorable operating condition could be obtained through the electrochemical course, when electrolysis time was 60 min, current density was 8 A, and electrode span was 1 cm. Under this condition, total organic carbon (TOC) removal efficiency could reach 73%, and the removal mechanism had also been analyzed. In addition, the electrodes’ morphology characteristics and components were analyzed through a scanning electron microscope, and the results showed that on the surface of anode and cathode electrodes there were quite a few cracks, the amount of which increased after use. Meanwhile, the content of chemical elements on the electrodes’ surface changed obviously after use – especially Ti content (from 39.66% to 92.69%) on the anode and Fe content (from 72.57% to 53.66%) on the cathode. The result was probably caused by the redox reaction, namely the shedding of the coating on the anode electrode’s surface, and reactions around the cathode electrode’s surface.

Radial oxygen loss (ROL) has been suggested to be a major process to protect plants exposed to the anaerobic by-products of soil anaerobiosis. The aim of the present study was to test the effects of root ROL from two submerged plants (Hydrilla verticillata and Vallisneria spiralis) on the rhizosphere oxygen profile and rhizosphere microarea. Phospholipid fatty acids (PLFAs) of sediment samples were used to characterize and quantify the microbial community. The results showed clearly that there were significant differences between the two plants in radial oxygen loss, which affected rhizosphere physicochemical parameters and the microbial community. Rhizosphere total biomass, bacteria, gram-positive bacteria, actinomycetes, and microbial diversity of V. spiralis were significantly higher than those of H. verticillata. The present study highlights root ROL as a key parameter affecting the microbial community of the rhizosphere microarea.

Occurrences of harmful cyanobacterial blooms are a worldwide environmental problem in most eutrophic lake ecosystems. But what should be noticed is that cyanobacteria can be used as a useful resource due to the wide range of metabolites they produce. Nutrient partitioning using purple nonsulfur bacteria (PNSB) has the potential to biologically concentrate nutrients. The present study evaluated the kinetics of nutrients released from decomposed field blue green algae (BGA) biomasses. The potential of nutrient acquisition from decomposed BGA biomasses for culturing Rhodopseudomonas palustris (R. palustris) was investigated via fed-batch experiments. Results indicated that R. palustris stimulated in algae substrates with algae biomasses ranging from 3.33 to 10 g/L. Removal efficiencies of N and P in the stationary phase of growth were at least 40% and 95%, respectively, of all the nitrogen (N) and phosphorus (P) released. Additionally, the cellular contents like total lipid and poly-β-hydroxybutyrate (PHB), as well as the fatty acids produced by R. palustris, were consistent. Hence, practice based on the bacterial production for the nutrient recovery from BGA biomasses provides a new insight in field algae disposal. It will lower the chances of secondary pollution due to algae decay and produce giant cells of R. palustris and surely will prosper the industries applying R. palustris.

Aerobic anoxygenic phototrophic (AAP) bacteria are known functionally as photoheterotrophic microbes. Though numerously reported from ocean habitats, their distribution in freshwater lakes is far less documented. In the present study we investigated the dynamics of AAP bacteria in freshwater plateau lakes. Results revealed a high abundance of AAP bacteria in eutrophic lakes. Moreover, AAP bacteria were positively correlated with TN, TP, and Chl a, but the variations of AAP bacterial proportion to potential total bacteria (AAPB%). Alphaproteobacteria-related sequences dominated lakes Luguhu, Erhai, and Chenghai at ratios of 93.9, 85.4, and 70.6%, respectively, and in total comprised eight clearly defined subgroups. Sequences affiliated with Beta- and Grammaproteobacteria were found to be rare taxa. Additionally, Alkalibacterium-like sequences belonging to Firmutes were assigned. Overall, sequences from Alpha-, Beta-, Gammaproteobacteria, and Firmutes separately comprised of 81.6, 8.8, 0.8, and 4.0%. Our present work revealed extreme dynamics of AAP bacteria in both water columns and non-euphotic sediments of plateau aquatic ecosystems, which consolidated their wide distribution and enhanced adaptation.
