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.
