Abstract

A rapid and reliable method to assess the potential specific activity of methagenic sludge is presented. The method is based on the gas chromatographic analysis for methane in the headspace of closed vials. Gas is sampled with a pressure lock syringe, which allows quantification independent of the pressure prevailing in the vials.

The influence of various parameters as substrates, pH, NaCl and NH₄ Cl concentrations on the activity of methaogenic sludge was investigated with this method. Data on the methanogenic activities on different substrate are discussed in terms of different physiological groups present in the sludge.

Auto-selection of microorganisms of sewage sludge used as an inoculum for fermentative hydrogen production from different substrates
2021, International Journal of Hydrogen Energy
When mixed organic waste is used for hydrogen production by dark fermentation, the microbial community which is most adapted to the actual biopolymer composition of the substrate is auto-selected. In this research, six substrates simulating different biopolymers (proteins, fats, carbohydrates) and their mixtures were used to enrich hydrogen-producing bacteria adapted to these substrates from non-pretreated sewage sludge. Phylum Firmicutes dominated in the microbial community (67–100%) regardless of the substrate used, as was shown by high-throughput sequencing. Microbial diversity was low when using carbohydrate-rich substrates and the microbial community was mainly represented by Ruminococcus (26–90%) and Thermoanaerobacterium (6–67%). Dark fermentation of fats and proteins was characterized by higher microbial diversity. Thermoanaerobacterium (21%), Thermobrachium (19%), Tepidiphilus (16%) and Acetomicrobium (14%) dominated when using fats, while Thermobrachium (34%), Acetomicrobium (16%) and Clostridium sensu stricto 7 (12%) dominated when using proteins, as substrate. Different microbial communities and substrates resulted in diverse process performance and metabolic pathways. Dark fermentation of starch achieved the maximum hydrogen yield of 138 mL/g volatile solids with 60.4% hydrogen content in biogas. The dominance of genus Ruminococcus was thought to be responsible for the highest hydrogen production. Minor quantities of methane from proteins and fats were produced by Methanothermobacter and Methanosarcina. Based upon the stable ¹³C isotope analysis, the hydrogenotrophic pathway was a slightly more predominant methane formation route than the others considered.
Hydrogenotrophic activity: A tool to evaluate the kinetics of methanogens
2020, Journal of Environmental Management
Anaerobic-digestion-based technology is key to achieving sustainable water management and resource recovery. It is essential to understand the material flux and kinetics involved in methanogenesis to optimize the organic matter removal and methane production. In this sense, specific methanogenic activity is a cost-effective tool to characterize the biological activity of anaerobic biosludge, to monitor the performance of reactors, and study the kinetics of acetate and H₂ conversion to methane. Established protocols are applied for the acetoclastic activity test. However, hydrogenotrophic activity assay remains less widespread and is not standardized. In this work, the assay design for hydrogenotrophic activity is discussed and full calculation is presented, based on the kinetics for the H₂/CO₂ conversion to methane. An equation to calculate the inoculum size is proposed, suitable for a wide variety of types of biosludge: from a wastewater treatment plant to solid digesters, from a high-rate reactor to lagoons. The applied zero-order model fitted adequately to data for pilot-scale and full-scale anaerobic reactors: the p-values from the ANOVA F-test were below 1E-03; standard deviations for triplicate experiments were between 3 and 12%, coherent with the values found in the literature. Microbial growth during the test was negligible, below 1.2% of the biomass dosed in the vial. As a complement, acetoclastic activity was determined for each sample. The use of both acetoclastic and hydrogenotrophic activity is relevant for the study of the methanogenesis and gives a better characterization of the performance of the biosludge in anaerobic reactors rather than only using the specific acetoclastic methanogenic activity.
Use of polymeric scouring agent as fluidized media in anaerobic fluidized bed membrane bioreactor for wastewater treatment: System performance and microbial community

Specific methane activity (SMA) test that can identify the maximum methane production from a particular substrate was conducted to investigate microbial activity associated with fluidized PVDF media. The SMA test was carried out by using the method designed by Dolfing and Bloeman (1985) [29]. The purpose of the SMA test was to investigate the role of PVDF media regarding biomass growth and methane production from AFMBR accordingly.
New attempts using polymeric media with a tubular shape consisting of polyvinylidene fluoride (PVDF) were made as fluidized agent for anaerobic fluidized bed membrane bioreactor (AFMBR) in wastewater treatment. The AFMBR added with PVDF media was operated at room temperature and hydraulic retention time (HRT) from 4 to 16 h to investigate membrane fouling, organic removal efficiency, and microbial structure. Results showed that the PVDF media reduced membrane fouling effectively due to their scouring actions to clean the membrane. Transmembrane pressure (TMP) was maintained less than 0.1 bar during the operational period. More than 90% of chemical oxygen demand (COD) removal was achieved, yielding 10 mg/L of COD in membrane permeate. The energy required to operate the AFMBR using PVDF media was only 1.09 $\times$ 10⁻² kWh/m³. The electrical energy produced by AFMBR was 0.246 kWh/m³, which is much higher than that required for system operation. Microbial community analysis based on 16S rRNA gene sequencing showed that the microbial community on PVDF biofilm was distinct from that in the suspended microbes. Importantly, it was found that dominant propionate-catabolizing bacteria on PVDF media include Desulfobulbus and syntroph Syntrophobacter while the key methanogenic player shifted from hydrogenotrophic Methanolinea to acetoclastic Methanothrix during the operation.

This study also aimed to find out the higher NaOCl concentration range that can possibly be tolerated for efficient in-situ membrane cleaning without compromising with microbial safety in the AFMBR, containing GAC as a biocarrier. The specific acetoclastic methanogenic activity (SAMA) test as described by Dolfing and Bloeman (1985) was carried out to evaluate the activity of the anaerobic bacteria. In this study, 500 mL serum bottles were first filled separately with GAC and bulk liquid followed by addition of substrate and nutrient.
The effect of membrane cleaning chemical, NaOCl on specific acetoclastic methanogenic activity (SAMA) of biomass in the anaerobic fluidized membrane bioreactors (AFMBRs) was assessed. Granular activated carbon (GAC) was used as a fluidizing media in the AFMBR to provide membrane scouring effect and surface for biofilm attachment. Effect of NaOCl on methane production was negligible for GAC with biofilm (bGAC) samples up to 150 mg NaOCl/g VSS, but was significant for the bulk liquid samples with noticeable lag period over 300 h even at the dosage of 50 mg NaOCl/g VSS. The toxicity of NaOCl on methane production was reduced in samples with virgin GAC (vGAC) by allowing 14 days of biomass buildup period prior to NaOCl addition, although the vGAC alone did not alleviate the toxicity. The results revealed that NaOCl concentrations beyond 100 mg/L within the reactor inhibited methanogenic activity and the effects were more pronounced on suspended biomass than the immobilized biomass on GAC.
A comparison of process performance during the anaerobic mono- and co-digestion of slaughterhouse waste through different operational modes
2018, Journal of Environmental Sciences (China)
The use of consecutive feeding was applied to investigate the response of the microbial biomass to a second addition of substrates in terms of biodegradation using batch tests as a promising alternative to predict the behavior of the process. Anaerobic digestion (AD) of the slaughterhouse waste (SB) and its co-digestion with manure (M), various crops (VC), and municipal solid waste were evaluated. The results were then correlated to previous findings obtained by the authors for similar mixtures in batch and semi-continuous operation modes. AD of the SB failed showing total inhibition after a second feeding. Co-digestion of the SB + M showed a significant improvement for all of the response variables investigated after the second feeding, while co-digestion of the SB + VC resulted in a decline in all of these response variables. Similar patterns were previously detected, during both the batch and the semi-continuous modes.
Alkali-assisted membrane cleaning for fouling control of anaerobic ceramic membrane bioreactor

This result did not correlate well with the F420 activities. Although coenzyme F420 has been detected in all methanogenic bacteria (Dolfing and Bloemen, 1985), it cannot be a indicator of the total methanogenic activity but rather a parameter reflecting the behaviours of hydrogenotrophic methanogenic microbes, as reported previously (Dolfing and Mulder, 1985; Zabranska et al., 1985). On the other hand, acetotrophic methanogenesis is widely regarded as the predominant pathway for treating low strength wastewater (Demirel and Scherer, 2008).
In this study, a chemically enhanced backflush (CEB) cleaning method using NaOH solution was proposed for fouling mitigation in anaerobic membrane bioreactors (AnMBRs). Ex-situ cleaning tests revealed that NaOH dosages ranging from 0.05 to 1.30 mmol/L had positive impacts on anaerobic biomass, while higher dosages (>1.30 mmol/L) showed inhibition and/or toxic impacts. In-situ cleaning tests showed that anaerobic biomass could tolerate much higher NaOH concentrations due to the alkali consumption by anaerobic process and/or the buffering role of mixed liquor. More importantly, 10–20 mmol-NaOH/L could significantly reduce membrane fouling rates (4–5.5 times over the AnMBR with deionized water backflush) and slightly improve methanogenic activities. COD removal efficiencies were over 87% and peaked at 20 mmol-NaOH/L. However, extremely high NaOH concentration had adverse effects on filtration and treatment performance. Economic analysis indicated that 12 mmol/L of NaOH was the cost-efficient and optimal fouling-control dosage for the CEB cleaning.
