C. vulgaris in ADMW had the lowest biomass production, reaching 2.0\u00a0g\u00a0L\u22121. Both microalgae removed ammonium efficiently from ADPP (99.9% removal) while the final ammonium removal efficiencies from ADMW with S. acuminatus and C. vulgaris were only 44.0 and 23.8%, respectively. The phosphate removal efficiencies from both ADPP and ADMW were higher than 96.9% with both microalgae. The highest carbohydrate content (60.5%) was obtained with S. acuminatus cultivated in ADPP.

The S2O32\u2212 removal efficiency decreased to 76% and 26% at N/S ratios of 0.3 and 0.1, respectively, and recovered to 80% within 3 days after increasing the N/S ratio from 0.1 back to 0.5. The highest observed half-saturation (Ks) and inhibition (KI) constants of the biofilm-grown NR-SOB obtained from batch cultivations were 172 and 800\u202fmg S-S2O32\u2212 L\u22121, respectively. Thiobacilus denitrificans was the dominant microorganism in the FBR. Artificial neural network modeling successfully predicted S2O32\u2212 and NO3\u2212 removal efficiencies and SO42\u2212 production in the FBR. Additionally, results from the sensitivity analysis showed that the effluent pH was the most influential parameter affecting the S2O32\u2212 removal efficiency.", "keywords": ["116 Chemical sciences", "0211 other engineering and technologies", "116", "02 engineering and technology", "540", "01 natural sciences", "6.

At both 37 and 55\u00a0\u00b0C, the fresh activated sludge yielded more H2 than the digested sludge, whereas at 70\u00a0\u00b0C, neither of the inocula produced H2 effectively. A maximum yield of 1.85\u00a0mol H2 per mol of xylose consumed was obtained at 55\u00a0\u00b0C. H2 production was linked to acetate and butyrate production, and there was a linear correlation (R2\u00a0=\u00a00.96) between the butyrate and H2 yield for the fresh activated sludge inoculum at 55\u00a0\u00b0C. Approximately 2.4\u00a0mol H2 per mol of butyrate produced were obtained against a theoretical maximum of 2.0, suggesting that H2 was produced via the acetate pathway prior to switching to the butyrate pathway due to the increased H2 partial pressure. Clostridia sp. were the prevalent species at both 37 and 55\u00a0\u00b0C, irrespectively of the inoculum type. Although the two inocula originated from the same plant, different thermophilic microorganisms were detected at 55\u00a0\u00b0C. Thermoanaerobacter sp., detected only in the fresh activated sludge cultures, may have contributed to the high H2 yield obtained with such an inoculum.", "keywords": ["Xylose", "Sewage", "116 Chemical sciences", "116", "02 engineering and technology", "01 natural sciences", "6.

Lipids are present in various wastewaters and have a high methanogenic potential, but their hydrolysis results in the production of long chain fatty acids (LCFAs) that are inhibitory to anaerobic microorganisms. Screening of inoculum for the anaerobic treatment of LCFA-containing wastewaters has been performed at mesophilic and thermophilic conditions. However, an evaluation of inocula for producing methane from LCFA-containing wastewater has not yet been conducted at low temperatures and needs to be undertaken. In this study, three inocula (one granular sludge and two municipal digester sludges) were assessed for methane production from LCFA-containing synthetic dairy wastewater (SDW) at low temperatures (10 and 20\uffc2\uffb0C). A methane yield (based on mL-CH4/g-CODadded) of 86-65% with acetate and 45-20% with SDW was achieved within 10 days using unacclimated granular sludge, whereas the municipal digester sludges produced methane only at 20\uffc2\uffb0C but not at 10\uffc2\uffb0C even after 200 days of incubation. The acetotrophic activity in the inoculum was found to be crucial for methane production from LCFA at low temperatures, highlighting the role ofMethanosaeta(acetoclastic archaea) at low temperatures. The presence of bacterial taxa from the familySyntrophaceae(Syntrophusand uncultured taxa) in the inoculum was found to be important for methane production from SDW at 10\uffc2\uffb0C. This study suggests the evaluation of acetotrophic activity and the initial microbial community characteristics by high-throughput amplicon sequencing for selecting the inoculum for producing methane at low temperatures (up to 10\uffc2\uffb0C) from lipid-containing wastewaters.</p>", "keywords": ["Deltaproteobacteria", "0301 basic medicine", "570", "0303 health sciences", "Sewage", "218 Environmental engineering", "Microbiota", "116 Chemical sciences", "Fatty Acids", "Temperature", "116", "Acetates", "Methanosarcinales", "6.
