    The performance, microbial community and enzymatic activity of a sequencing batch reactor (SBR) were evaluated at different silica nanoparticles (SiO2 NPs) concentrations. SiO2 NPs concentration at 5-30mg/L had a slight inhibitory impact on the nitrogen and COD removals, whereas the phosphorus removal was obviously inhibited at 30mg/L SiO2 NPs. The rates of nitrification, nitrite reduction and phosphorus removal decreased with the increase of SiO2 NPs concentration. Read More

    Effect of single-function (oil degrading) and multi-functional bacterial consortium with zeolite as additive for post-consumption food waste (PCFW) composting was investigated through assessing the oil content reduction in a computer controlled 20-L composter. Three treatments of PCFWs combined with 10% zeolite were developed: Treatment-2 and Treatment-3 were inoculated with multi-functional (BC-1) and oil degrading bacterial consortium (BC-2), respectively, while T-1 was without bacterial inoculation and served as control. Results revealed that BC-2 inoculated treatment (T-3) was superior to control treatment and marginally better than T-2 in terms of oil degradation. Read More

    In this paper, a state-of-art about solid anaerobic digestion (AD), focused on recent progress and trends of research is proposed. Solid anaerobic digestion should be the most appropriate process for degradation of by-products with high total solid (TS) content, especially lignocellulosic materials like agricultural waste (straw, manure), household waste and food waste. Solid AD is already widely used in waste water treatment plant for treating plant for sewage sludge but could be more developed for lignocellulosic materials with high TS content. Read More

    Electron receptor addition enhances butanol synthesis in ABE fermentation by Clostridium acetobutylicum.

    The techniques for enhancing butanol production in ABE fermentation by Clostridium acetobutylicum generally focus on adding electron carrier to strengthen NADH synthesis, repressing hydrogenase by aerating CO, supplementing butyrate, etc. However, those methods suffer from the problems of total solvent decrease, high purification cost, using expensive supplemental substances, etc. In this study, we added small amount of electron receptors (Na2SO4/CaSO4, 2g/L) into ABE fermentation broth: to alter electron/proton distributions in the intracellular electron transport shuttle system, directing more electron/proton pairs into NADH synthesis route; to stimulate intracellular accumulation of those amino acids favorable for cells survival/butanol synthesis.
