Abstract
Treatment of organic wastewater is a challenging task. Biological techniques using biocatalysts have shown their benefits in organic wastewater treatment. In this research, a novel biocatalyst was developed by encapsulation of Fe3O4 microspheres and haemoglobin (Hb) with mesoporous silica, named Fe3O4@mSiO2(Hb). Fe3O4@mSiO2(Hb) exhibited typical mesoporous characteristics (mesoporous silica), magnetic feature (Fe3O4) and peroxidase activity (Hb). The results showed that the immobilization of Hb into Fe3O4@mSiO2 did not affect its activity. In addition, Fe3O4@mSiO2(Hb) exhibited a higher efficiency in the peroxidation of aromatic compounds than free Hb. The peroxidase activity of the synthesized biocatalyst was estimated to be 120 Ug-1, which was almost four times greater than that of previously reported immobilized Hb. Also, the Km of Fe3O4@mSiO2(Hb) was similar to that of the free Hb and it was estimated to be 4.3 × 10-4 μM, indicating that the activity of the Hb in the immobilized enzyme was not affected after immobilization. The immobilized enzyme was also found to be stable, recyclable and reusable. Taken together, these results indicate that the Fe3O4@mSiO2(Hb) has good potential to be used for treating organic wastewater containing aromatic compounds. The magnetically separable novel biocatalyst developed in this study provided not only a more suitable microenvironment for retaining the activity of Hb, but also demonstrated enhanced stability and activity under unfavorable conditions.

Abstract
Membrane fouling is the major factor limiting the wider applicability of the membrane-based technologies in water treatment and in separation and purification processes of biorefineries, pulp and paper industry, food industry and other sectors. Endeavors to prevent and minimize fouling requires a deep understanding on the fouling mechanisms and their relative effects. In this study, Brunauer-Emmett-Teller (BET) nitrogen adsorption/desorption technique was applied to get an insight into pore-level membrane fouling phenomena occurring in ultrafiltration of wood-based streams. The fouling of commercial polysulfone and polyethersulfone membranes by black liquor, thermomechanical pulping process water and pressurized hot-water extract was investigated with BET analysis, infrared spectroscopy, contact angle analysis and pure water permeability measurements. Particular emphasis was paid to the applicability of BET for membrane fouling characterization. The formation of a fouling layer was detected as an increase in cumulative pore volumes and pore areas in the meso-pores region. Pore blocking was seen as disappearance of meso-pores and micro-pores. The results indicate that the presented approach of using BET analysis combined with IR spectroscopy can provide complementary information revealing both the structure of fouling layer and the chemical nature of foulants.

Abstract
Polysorbate 80 is one of the key components of protein formulations. It primarily inhibits interfacial damage of the protein molecule due to mechanical stress during shipping and handling. However, polysorbate 80 also affects the formulation photostability. Exposure to light of polysorbate 80 aqueous solution results in peroxide generation, which in turn may result in oxidation of the susceptible amino acid residues in the protein molecule. The purpose of this study was to determine if the photostability of our proprietary IgG(1) monoclonal antibody formulation containing polysorbate 80 is affected by the quality (grade/vendor) of polysorbate 80. Following four types of polysorbate 80 were tested: (1) Polysorbate 80 Super-Refined, Mallinckrodt Baker, (2) Polysorbate 80 NF, Mallinckrodt Baker, (3) Polysorbate 80 NF, EMD Chemicals, and (4) Ultra-pure Polysorbate 80 (HX), NOF Corporation. The samples were exposed to light as per ICH guidelines Q1B. The results of the study show that photostability of the antibody formulation is indeed affected by the quality of polysorbate 80. This study underscores the importance of carefully choosing the quality of polysorbate 80 to ensure the robustness of formulation.

Abstract
In 1989, Manning, Patel, and Borchardt wrote a review of protein stability (Manning et al., Pharm. Res. 6:903-918, 1989), which has been widely referenced ever since. At the time, recombinant protein therapy was still in its infancy. This review summarizes the advances that have been made since then regarding protein stabilization and formulation. In addition to a discussion of the current understanding of chemical and physical instability, sections are included on stabilization in aqueous solution and the dried state, the use of chemical modification and mutagenesis to improve stability, and the interrelationship between chemical and physical instability.
