Abstract
BACKGROUND In biogas plants, complex microbial communities produce methane and carbon dioxide by anaerobic digestion of biomass. For the characterization of the microbial functional networks, samples of 11 reactors were analyzed using a high-resolution metaproteomics pipeline. RESULTS Examined methanogenesis archaeal communities were either mixotrophic or strictly hydrogenotrophic in syntrophy with bacterial acetate oxidizers. Mapping of identified metaproteins with process steps described by the Anaerobic Digestion Model 1 confirmed its main assumptions and also proposed some extensions such as syntrophic acetate oxidation or fermentation of alcohols. Results indicate that the microbial communities were shaped by syntrophy as well as competition and phage-host interactions causing cell lysis. For the families Bacillaceae, Enterobacteriaceae, and Clostridiaceae, the number of phages exceeded up to 20-fold the number of host cells. CONCLUSION Phage-induced cell lysis might slow down the conversion of substrates to biogas, though, it could support the growth of auxotrophic microbes by cycling of nutrients.

Abstract
BACKGROUND Methane yield and biogas productivity of biogas plants (BGPs) depend on microbial community structure and function, substrate supply, and general biogas process parameters. So far, however, relatively little is known about correlations between microbial community function and process parameters. To close this knowledge gap, microbial communities of 40 samples from 35 different industrial biogas plants were evaluated by a metaproteomics approach in this study. RESULTS Liquid chromatography coupled to tandem mass spectrometry (Orbitrap Elite™ Hybrid Ion Trap-Orbitrap Mass Spectrometer) of all 40 samples as triplicate enabled the identification of 3138 different metaproteins belonging to 162 biological processes and 75 different taxonomic orders. The respective database searches were performed against UniProtKB/Swiss-Prot and seven metagenome databases. Subsequent clustering and principal component analysis of these data allowed for the identification of four main clusters associated with mesophile and thermophile process conditions, the use of upflow anaerobic sludge blanket reactors and BGP feeding with sewage sludge. Observations confirm a previous phylogenetic study of the same BGP samples that was based on 16S rRNA gene sequencing by De Vrieze et al. (Water Res 75:312-323, 2015). In particular, we identified similar microbial key players of biogas processes, namely Bacillales, Enterobacteriales, Bacteriodales, Clostridiales, Rhizobiales and Thermoanaerobacteriales as well as Methanobacteriales, Methanosarcinales and Methanococcales. For the elucidation of the main biomass degradation pathways, the most abundant 1 % of metaproteins was assigned to the KEGG map 1200 representing the central carbon metabolism. Additionally, the effect of the process parameters (i) temperature, (ii) organic loading rate (OLR), (iii) total ammonia nitrogen (TAN), and (iv) sludge retention time (SRT) on these pathways was investigated. For example, high TAN correlated with hydrogenotrophic methanogens and bacterial one-carbon metabolism, indicating syntrophic acetate oxidation. CONCLUSIONS This is the first large-scale metaproteome study of BGPs. Proteotyping of BGPs reveals general correlations between the microbial community structure and its function with process parameters. The monitoring of changes on the level of microbial key functions or even of the microbial community represents a well-directed tool for the identification of process problems and disturbances.Graphical abstractCorrelation between the different orders and process parameter, as well as principle component analysis of all investigated biogas plants based on the identified metaproteins.

Abstract
A model has been developed for the determination of the correct absolute size of nanoparticles using a disc centrifuge; the method does not require externally measured or literature derived particle densities. The principle of this method is the altered settling velocity of particles in fluids with different viscosities and/or densities, with the use of a linear regression analysis for the calculation of particle densities. This allows a fast particle density determination with at least two measurements using a disc centrifuge and a small subset of easily measurable parameters. Furthermore, correctness of the model is evaluated using viruses and nonbiological particles of known densities.

Abstract
To mitigate the diesel particle pollution problem, diesel vehicles are fitted with modern exhaust after-treatment systems (ATS), which efficiently remove engine-generated primary particles (soot and ash) and gaseous hydrocarbons. Unfortunately, ATS can promote formation of low-vapor-pressure gases, which may undergo nucleation and condensation leading to formation of nucleation particles (NUP). The chemical nature and formation mechanism of these particles are only poorly explored. Using a novel mass spectrometric method, online measurements of low-vapor-pressure gases were performed for exhaust of a modern heavy-duty diesel engine operated with modern ATS and combusting low and ultralow sulfur fuels and also biofuel. It was observed that the gaseous sulfuric acid (GSA) concentration varied strongly, although engine operation was stable. However, the exhaust GSA was observed to be affected by fuel sulfur level, exhaust after-treatment, and driving conditions. Significant GSA concentrations were measured also when biofuel was used, indicating that GSA can be originated also from lubricant oil sulfur. Furthermore, accompanying NUP measurements and NUP model simulations were performed. We found that the exhaust GSA promotes NUP formation, but also organic (acidic) precursor gases can have a role. The model results indicate that that the measured GSA concentration alone is not high enough to grow the particles to the detected sizes.

Abstract
In cell culture-based influenza vaccine production significant efforts are directed towards virus seed optimization for maximum yields. Typically, high growth reassortants (HGR) containing backbones of six gene segments of e.g. influenza A/PR/8, are generated from wild type strains. Often, however, HA and TCID₅₀ titres obtained do not meet expectations and further optimization measures are required. Flow cytometry is an invaluable tool to improve our understanding of mechanism related to progress of infection, virus-induced apoptosis, and cell-specific productivity. In this study, we performed infections with two influenza A/PR/8 variants (from NIBSC and RKI) and two A/PR/8-based HGRs (Wisconsin-like and Uruguay-like) to investigate virus replication, apoptosis and virus titres at different multiplicities of infection (MOI 0.0001, 0.1, 3). Flow cytometric analyses showed similar dynamics in the time course of infected and apoptotic cell populations for all four tested strains at MOI 0.0001. Interestingly, higher MOI resulted in an earlier increase of the populations of infected and apoptotic cells and showed strain-specific differences. Infections with A/PR/8 NIBSC resulted in an earlier increase in both cell populations compared to A/PR/8 RKI. The Uruguay-like reassortant showed the earliest increase in the concentration of infected cells and a late induction of apoptosis at all tested MOIs. In contrast, the Wisconsin-like reassortant showed strong apoptosis induction at high MOIs resulting in reduced titres compared to lower MOI. Maximum HA titres were unaffected by changes in the MOI for the two A/PR/8 and the Uruguay-like reassortant. Maximum TCID₅₀ titres, however, decreased with increasing MOI for all strains. Overall, infections at very low MOI (0.0001) resulted not only in similar dynamics concerning progress of infection and induction of apoptosis but also in maximum virus yields. Highest HA titres were obtained for virus seed strains combining a fast progress in infection with a late onset of apoptosis. Therefore, both factors should be considered for the establishment of robust influenza vaccine production processes.

Abstract
Lactate and ammonia are the most important waste products of central carbon metabolism in mammalian cell cultures. In particular during batch and fed-batch cultivations these toxic by-products are excreted into the medium in large amounts, and not only affect cell viability and productivity but often also prevent growth to high cell densities. The most promising approach to overcome such a metabolic imbalance is the replacement of one or several components in the culture medium. It has been previously shown that pyruvate can be substituted for glutamine in cultures of adherent Madin-Darby canine kidney (MDCK) cells. As a consequence, the cells not only released no ammonia but glucose consumption and lactate production were also reduced significantly. In this work, the impact of media changes on glucose and glutamine metabolism was further elucidated by using a high-throughput platform for enzyme activity measurements of mammalian cells. Adherent MDCK cells were grown to stationary and exponential phase in six-well plates in serum-containing GMEM supplemented with glutamine or pyruvate. A total number of 28 key metabolic enzyme activities of cell extracts were analyzed. The overall activity of the pentose phosphate pathway was up-regulated during exponential cell growth in pyruvate-containing medium suggesting that more glucose-6-phosphate was channeled into the oxidative branch. Furthermore, the anaplerotic enzymes pyruvate carboxylase and pyruvate dehydrogenase showed higher cell specific activities with pyruvate. An increase in cell specific activity was also found for NAD(+)-dependent isocitrate dehydrogenase, glutamate dehydrogenase, and glutamine synthetase in MDCK cells grown with pyruvate. It can be assumed that the increase in enzyme activities was required to compensate for the energy demand and to replenish the glutamine pool. On the other hand, the activities of glutaminolytic enzymes (e.g., alanine and aspartate transaminase) were decreased in cells grown with pyruvate, which seems to be related to a decreased glutamine metabolism.

Abstract
The GUT1 gene of the halotolerant yeast Pichia farinosa, encoding glycerokinase (EC 2.7.1.30), was expressed in Pichia pastoris. A purification factor of approximately 61-fold was achieved by a combination of nickel affinity and anion exchange chromatography. The specific activity of the final preparation was 201.6 units per mg protein with a yield of about 21%. A nearly homogeneous enzyme preparation was confirmed by SDS-polyacrylamide gels and mass spectrometry analysis. Glycerol stabilized the purified enzyme for long-term storage at -80°C. The pH and temperature optima were in the range of 6.5-7.0 and 45-50°C, respectively. ATP was the most effective phosphoryl group donor tested. Additionally, the enzyme phosphorylated glycerol also with ITP, UTP, GTP and CTP. The K(m) values of the enzyme for ATP and ITP were 0.428 and 0.845 mM, respectively. The kinetic properties of the enzyme with respect to UTP, GTP, and CTP suggested that glycerokinase exhibited negative cooperativity as double reciprocal plots showed a biphasic response to increasing nucleoside triphosphate concentrations. The application as a coupling enzyme in the determination of pyruvate kinase activity in cell extracts of Madin-Darby canine kidney cells showed good reproducibility when compared with a commercially available preparation of bacterial glycerokinase.

Abstract
An adherently growing MDCK cell line was adapted in a two-step process in a fully defined medium and in suspension. The resulting MDCK.SUS2 cells were subsequently evaluated for their potential as host cells for influenza vaccine production in two lab-scale bioreactors (wave and stirred-tank). Cell concentrations up to 2.3 x 10(6)cells/mL were obtained after 96 h, which is slightly higher than cell concentrations obtained with adherent MDCK cells cultivated on microcarriers (2g/L). Infections with influenza A/PR/8/34 and B/Malaysia resulted in high virus titers (2.90 and 2.75 log HA units/100 microL, respectively). The monitoring of extracellular metabolites, including amino acids, revealed a change in some of the metabolite consumption or release profiles, which indicates changes in metabolism during the adaptation process. Overall, the MDCK.SUS2 cell line represents a new cell substrate for a robust influenza vaccine production in a fully defined process.

Abstract
The establishment of cell culture-derived vaccine production requires the development of appropriate downstream processes. Until today, many of the downstream methods applied originate from egg-derived production processes. These methods have often been slightly modified in order to account for the new demands. However, efforts are currently underway to optimize these processes focusing, for example, on ion exchange or affinity based membrane adsorption chromatography. This review covers the main aspects relevant for the downstream processing of egg and mammalian cell culture-derived whole influenza viruses.

Abstract
For the production of a chemically inactivated Parapoxvirus ovis (PPVO), an adherent bovine kidney cell line was cultivated on Cytodex-3 microcarriers in suspension culture. The inactivated and purified virus particles have shown immune modulatory activity in several animal models. PPVO was produced by a biphasic batch process at the 3.5 and 10 L scale. Aeration was realised by bubble-free membrane oxygenation via a tube stator with a central two-blade anchor impeller. In order to increase efficiency, process robustness and safety, the established process was optimised. The cell line was adapted to a protein-free medium (except recombinant insulin) in order to increase biosafety. A scale up to a 50 L pilot plant with direct cell expansion was performed successfully. In parallel, the biphasic batch process was optimised with special emphasis on different operating conditions (cell number, Multiplicity of Infection (MOI), etc.) and process management (fed-batch, dialysis, etc.). The quality and concentration of the purified virus particles was assessed by quantitative electron microscopy, residual host cell protein and DNA-content and, finally, biologic activity in a transgenic mouse model. This integrated approach led to a new, safe, robust and highly productive large-scale production process, called "Volume-Expanded-Fed" Batch with cell densities up to 6-7e06 cells/mL. By subsequent dilution of infected cells into the next process scale, an increase in total productivity by a factor of 40 (related to an established biphasic batch process) was achieved.
