Abstract
Recombinant proteins have broad applications. However, there is a lack of a recombinant protein expression system specifically for large-scale production in anaerobic hosts. Here, we developed a powerful and stringently inducible protein expression system based on the bacteriophage T7 system in the strictly anaerobic solvent-producing Clostridium saccharoperbutylacetonicum. With the integration of a codon optimized T7 RNA polymerase into the chromosome, a single plasmid carrying a T7 promoter could efficiently drive high-level expression of the target gene in an orthogonal manner, which was tightly regulated by a lactose-inducible system. Furthermore, by deleting beta-galactosidase genes involved in lactose metabolism, the transcriptional strength was further improved. In the ultimately optimized strain TM-07, the transcriptional strength of the T7 promoter showed 9.5-fold increase compared to the endogenous strong promoter Pthl. The heterologous NADP+-dependent 3-hydroxybutyryl-CoA dehydrogenase (Hbd1) from C. kluyveri was expressed in TM-07, and the yield of the recombinant protein reached 30.4-42.4% of the total cellular protein, surpassing the strong protein expression systems in other Gram-positive bacteria. The relative activity of Hbd1 in the crude enzyme was 198.0 U/mg, which was 8.3-fold higher than the natural activity in C. kluyveri. The relative activity of the purified enzyme reached 467.4 U/mg. To the best of our knowledge, this study represents the first application of the T7 expression system in Clostridium species, and this optimized expression system holds great potential for large-scale endotoxin-free recombinant protein production under strictly anaerobic conditions. This development paves the way for significant advancements in biotechnology and opens up new avenues for industrial applications.

Abstract
Dissolved oxygen (DO)-stat fed-batch culture, which allows a high cell density culture of microorganisms under constant DO conditions, was applied to anti-CRP single-chain variable fragment (scFv) production using recombinant Escherichia coli. The DO-stat fed-batch culture was successfully performed under various DO conditions for more than 50 h, resulting in increased scFv production from 0.5 to 0.8 g/L by flask and batch cultures to 2.8-3.0 g/L by the fed-batch culture under the conditions of 5-40% of DO saturation. The formation of inclusion bodies was effectively depressed during DO-stat fed-batch operation; consequently, the solubility of anti-CRP scFv was significantly improved from 36-43% by the flask and batch cultures to 96-98% by the DO-stat fed-batch culture under a wide range of DO conditions. From the kinetic analysis of fed-batch experiments, it was also found that the successful folding of anti-CRP scFv in the cytoplasm occurred when metabolic rates, such as the specific growth rate and specific glucose consumption rate, were relatively low. These results show that the fed-batch culture operated by the DO-stat feeding strategy was effective for the enhanced production of anti-CRP scFv with high solubility.

Abstract
The bifidobacterial β-galactosidase (BbgIV) was produced in E. coli DH5α at 37 and 30 °C in a 5 L bioreactor under varied conditions of dissolved oxygen (dO2) and pH. The yield of soluble BbgIV was significantly (P < 0.05) increased once the dO2 dropped to 0-2% and remained at such low values during the exponential phase. Limited dO2 significantly (P < 0.05) increased the plasmid copy number and decreased the cells growth rate. Consequently, the BbgIV yield increased to its maximum (71-75 mg per g dry cell weight), which represented 20-25% of the total soluble proteins in the cells. In addition, the specific activity and catalytic efficiency of BbgIV were significantly (P < 0.05) enhanced under limited dO2 conditions. This was concomitant with a change in the enzyme secondary structure, suggesting a link between the enzyme structure and function. The knowledge generated from this work is very important for producing BbgIV as a biocatalyst for the development of a cost-effective process for the synthesis of prebiotic galactooligosaccharides from lactose.

Abstract
Mucopolysaccharidosis IVA (MPS IVA) is an autosomal recessive disorder caused by N-acetylgalactosamine-6-sulfate sulfatase (GALNS) deficiency. Currently no effective therapies exist for MPS IVA. In this work, production of a recombinant GALNS enzyme (rGALNS) in Escherichia coli BL21 strain was studied. At shake scale, the effect of glucose concentration on microorganism growth, and microorganism culture and induction times on rGALNS production were evaluated. At bench scale, the effect of aeration and agitation on microorganism growth, and culture and induction times were evaluated. The highest enzyme activity levels at shake scale were observed in 12 h culture after 2-4 h induction. At bench scale the highest enzyme activity levels were observed after 2 h induction. rGALNS amounts in inclusion bodies fraction were up to 17-fold higher than those observed in the soluble fraction. However, the highest levels of active enzyme were found in the soluble fraction. Western blot analysis showed the presence of a 50-kDa band, in both soluble and inclusion bodies fractions. These results show for the first time the feasibility and potential of production of active rGALNS in a prokaryotic system for development of enzyme replacement therapy for MPS IVA disease.

Abstract
Intensified bioprocess development requires parallelized medium- to high-throughput experimentation with high on- and offline data density across all early scales of the development trajectory from microtiter plate via shake flask to lab-scale reactor. We developed a widespread measurement principle for intermediate scales, respirometry, into a parallelized oxygen transfer rate measurement device that could accurately record common process development-relevant effects such as acetate formation, diauxic growth, and nutrient limitations. The device was further equipped with dissolved oxygen measurement capability and sampling ports that allowed repetitive monoseptic sample withdrawal without disturbing the cultivation. Optimization of the operating parameters lead to k(L) a values of up to 160 h(-1) and corresponding oxygen transfer rates of 1 g L(-1) h(-1) for cultivation volumes of 50 mL.

Abstract
A commercial process was developed for producing a recombinant vaccine against hydatidosis in farm animals. The vaccine antigen consisting of a surface protein of the oncospheres of the hydatid worm (Echinococcus granulosus), was produced as inclusion bodies in Escherichia coli. Fed-batch cultures of E. coli using Terrific broth in stirred bioreactors at 37 degrees C, pH 7.0, and a dissolved oxygen level of 30% of air saturation produced the highest volumetric concentrations of the final solubilized antigen. An exponential feeding strategy proved distinctly superior to feeding based on pH-stat and DO-stat methods. The plasmid coding for the antigen was induced with isopropyl-beta-D-thiogalactopyranoside (IPTG) at 4 h after initiation of the culture. The minimum IPTG concentration for full induction was 0.1 mM.

Abstract
Fermentations carried out at 450-L and 20-L scale to produce Fab' antibody fragments indicated a serious problem to control levels of dissolved oxygen in the broth due to the large oxygen demand at high cell densities. Dissolved oxygen tension (DOT) dropped to zero during the induction phase and it was hypothesised that this could limit product formation due to inadequate oxygen supply. A gas blending system at 20-L scale was employed to address this problem and a factorial 2(2) experimental design was executed to evaluate independently the effects and interaction of two main engineering factors: agitation rate and DOT level (both related to mixing and oxygen transfer in the broth) on Fab' yields. By comparison to the non-gas blending system, results in the gas blending system at same scale showed an increase in the production of Fab' by 77% independent of the DOT level when using an agitation rate of 500 rpm level and by 50% at an agitation rate of 1,000 rpm with 30% DOT. Product localisation in the cell periplasm of >90% was obtained in all fermentations. Results obtained encourage further studies at 450-L scale initially, to evaluate the potential of gas blending for the industrial production of Fab' antibody fragments.

Abstract
Growth inhibition of recombinant Escherichia coli during the expression of human epidermal growth factor was observed. The recombinant cells could be segregated into three populations based on their cell division and plasmid maintenance abilities: dividing and plasmid-bearing cells, dividing and plasmid-free cells, and viable-but-non-culturable (VBNC) cells. Fed-batch fermentations were performed to investigate the effect of cell segregation on the kinetics of growth and foreign protein production. The results showed that a low concentration of inducer caused weak induction, whereas high levels cause strong induction, resulting in cells segregating into VBNC bacteria and producing a low foreign protein yield. A kinetic model for cell segregation was proposed and its predictions correlated well with experimental data for cell growth and protein expression. The optimal induction strategy could then be predicted by the model, and this prediction was then verified by experimentally deriving the conditions necessary for maximum expression of recombinant protein.
