Abstract
Hairy root (HR) culture, a successful biotechnology combining in vitro tissue culture with recombinant DNA machinery, is intended for the genetic improvement of plants. This technology has been put to use since the last three decades for genetic advancement of medicinal and aromatic plants and also to harvest the economical products in the form of secondary metabolites that are significantly important for their ethnobotanical and pharmacological properties. It also provides an efficient way out for the quicker extraction and quantification of the valuable phytochemicals. The current review provides an account of the in vitro HR culture technology and its wide-scale applications in the field of research as well as in pharmaceutical industries. Different facets of HR with respect to the culture establishment, phytochemical production as well as research investigations concerning the areas of gene manipulation, biotransformation of the secondary metabolites, phytoremediation, their industrial utilisations and different problems encountered during the application of this technology have been covered in this appraisal. Eventually, an idea has been provided on HR about the recent trends on the progress of this technology that may open up newer prospects in near future and calls for further research and explorations in this field. KEY POINTS: • Genetic engineering-based HR culture aims towards enhanced secondary metabolite production. • This review explores an insight in the HR technology and its multi-faceted approaches. • Up-to-date ground-breaking research applications and constraints of HR culture are discussed.

Abstract
Microbioreactors are increasingly used within animal cell biotechnology to grow mammalian cells for cell line screening and to facilitate process development. Many such devices have been reported in the literature, but only a small number are available commercially. Microbioreactors range in complexity from simple plate-based systems to complex automated parallel bioreactors designed to enable the meaningful scale-down of conventional bioprocesses. The Micro24 MicroReactor system (Pall Life Sciences) fits between these extremes providing 24× 7 mL parallel "bioreactors" with individual monitoring and control of temperature, pH, and dissolved oxygen. Inoculation, sampling, and feed additions are carried out manually in a Biological Safety Cabinet. In this chapter we describe the use of the Micro24 system to carry out screening or process development experiments with CHO cells.

Process characterization of hCTLA4Ig production in transgenic rice cell cultures using a 3-L bioreactor. Appl Biochem Biotechnol 2013; 171:1276-88.

Abstract
Most of the technical know-how and experience of bioreactor engineering is applicable to plant cell cultures. In this study, transgenic rice cell cultures using RAmy3D promoter were used for the production of human cytotoxic T-lymphocyte antigen 4-immunoglobulin (hCTLA4Ig). In process aspect, the rice cells during production phase are strongly influenced by hydrodynamic stresses, such as shear stress and bubble burst. Therefore, the effects of agitation and aeration rates on cell growth and hCTLA4Ig production were investigated in a 3-L multi-bioreactor. By increasing over 240 rpm, the detrimental effects on cell growth and hCTLA4Ig production were observed. At an aeration rate of 0.3 vvm, relative cell viability sharply decreased 2 days earlier than those of lower aeration rates. In addition, it was confirmed that the specific yields and the specific productivity at 0.3 vvm were superior to those values at 0.05 vvm. Overall, higher aeration rate showed the improved hCTLA4Ig production in combination experiment. High aeration rates in general, however, have an undesired effect as excessive aeration was found to negatively affect the quality of hCTLA4Ig. Consequently, the hydrodynamic conditions must be tightly regulated during bioreactor operation in order to enhance hCTLA4Ig productivity and quality in transgenic rice cell cultures.

Abstract
This paper presents a vertically positioned microfluidic system made of poly(dimethylsiloxane) (PDMS) and glass, which can be applied as a microbubble column (μBC) for biotechnological screening in suspension. In this μBC, microbubbles are produced in a cultivation chamber through an integrated nozzle structure. Thus, homogeneous suspension of biomass is achieved in the cultivation chamber without requiring additional mixing elements. Moreover, blockage due to produced carbon dioxide by the microorganisms-a problem predominant in common, horizontally positioned microbioreactors (MBRs)-is avoided, as the gas bubbles are released by buoyancy at the upper part of the microsystem. The patterned PDMS layer is based on an optimized two-lithographic process. Since the naturally hydrophobic PDMS causes problems for the sufficient production of microbubbles, a method based on polyelectrolyte multilayers is applied in order to allow continuous hydrophilization of the already bonded PDMS-glass-system. The μBC comprises various microelements, including stabilization of temperature, control of continuous bubble formation, and two optical configurations for measurement of optical density with two different sensitivities. In addition, the simple and robust application and handling of the μBC is achieved via a custom-made modular plug-in adapter. To validate the scalability from laboratory scale to microscale, and thus to demonstrate the successful application of the μBC as a screening instrument, a batch cultivation of Saccharomyces cerevisiae is performed in the μBC and compared to shake flask cultivation. Monitoring of the biomass growth in the μBC with the integrated online analytics resulted in a specific growth rate of 0.32 h(-1), which is almost identical to the one achieved in the shake flask cultivation (0.31 h(-1)). Therefore, the validity of the μBC as an alternative screening tool compared to other conventional laboratory scale systems in bioprocess development is proven. In addition, vertically positioned microbioreactors show high potential in comparison to conventional screening tools, since they allow for high density of integrated online analytics and therefore minimize time and cost for screening and guarantee improved control and analysis of cultivation parameters.

Abstract
Miniaturized bioreactors for suspension cultures of animal cells, such as Chinese Hamster Ovary (CHO) cells, could improve bioprocess development through the ability to cheaply explore a wide range of bioprocess operating conditions. A miniaturized pressure-cycled bioreactor for animal cell cultures, described previously (Diao et al., 2008), was tested with a suspension CHO cell line producing commercially relevant quantities of human IgG. Results from the suspended CHO cell line showed that the cell growth was comparable to conventional flask controls and the target protein production was enhanced in the minibioreactor, which may be due to the relatively high oxygen transfer rate and the moderate shear stress, measured and simulated previously. Microcarrier culture using an anchorage-dependent CHO cell line and Cytodex 3 also showed a similar result: comparable growth and enhanced production of a model protein (secreted alkaline phosphatase or SEAP). Various fed-batch schemes were applied to the CHO cells producing human IgG, yielding cell numbers (1.1 × 10(7) /mL) at day 8 and titers of human IgG (2.3 g/L) at day 14 that are typical industrial values for CHO cell fed-batch cultures. The alteration of the volumetric oxygen transfer coefficient is a key parameter for viability of the CHO cell line producing human IgG. We conclude that the minibioreactor can provide favorable cell culture environments; oxygen transfer coefficient and mixing time can be altered to mimic values in a larger scale system allowing for potential prediction of response during scale-up.

Abstract
Plant cells have been demonstrated to be an attractive heterologous expression host (using whole plants and in vitro plant cell cultures) for foreign protein production in the past 20years. In recent years in vitro liquid cultures of plant cells in a fully contained bioreactor have become promising alternatives to traditional microbial fermentation and mammalian cell cultures as a foreign protein expression platform, due to the unique features of plant cells as a production host including product safety, cost-effective biomanufacturing, and the capacity for complex protein post-translational modifications. Heterologous proteins such as therapeutics, antibodies, vaccines and enzymes for pharmaceutical and industrial applications have been successfully expressed in plant cell culture-based bioreactor systems including suspended dedifferentiated plant cells, moss, and hairy roots, etc. In this article, the current status and emerging trends of plant cell culture for in vitro production of foreign proteins will be discussed with emphasis on the technological progress that has been made in plant cell culture bioreactor systems.

Abstract
Manufacture of recombinant proteins from mammalian cell lines requires the use of bioreactor systems at scales of up to 20,000 L. The cost and complexity of such systems can prohibit their extensive use during the process to construct and select the manufacturing cell line. It is therefore common practice to develop a model of the production process in a small scale vessel, such as a shake-flask, where lower costs, ease of handling, and higher throughput are possible. This model can then be used to select a small number of cell lines for further evaluation in bioreactor culture. Here, we extend our previous work investigating cell line construction strategies to assess how well the behavior of cell lines in such a shake-flask assessment predicts behavior in the associated bioreactor production process. A panel of 29 GS-CHO cell lines, all producing the same antibody, were selected to include a mixture of high and low producers from a pool of 175 transfectants. Assessment of this panel in 10 L bioreactor culture revealed wide variation in parameters including growth, productivity, and metabolite utilization. In general, those cell lines which were high producing in the bioreactor cultures had also been higher producing in an earlier shake-flask assessment. However, some changes in rank position of the evaluated cell lines were seen between the two systems. A potential explanation of these observations is discussed and approaches to improve the predictability of assessments used for cell line selection are considered.

Abstract
The pharmaceutical and biotech industries face continued pressure to reduce development costs and accelerate process development. This challenge occurs alongside the need for increased upstream experimentation to support quality by design initiatives and the pursuit of predictive models from systems biology. A small scale system enabling multiple reactions in parallel (n ≥ 20), with automated sampling and integrated to purification, would provide significant improvement (four to fivefold) to development timelines. State of the art attempts to pursue high throughput process development include shake flasks, microfluidic reactors, microtiter plates and small-scale stirred reactors. The limitations of these systems are compared to desired criteria to mimic large scale commercial processes. The comparison shows that significant technological improvement is still required to provide automated solutions that can speed upstream process development.

Abstract
Routine cell culture is done in small-scale disposable vessels (typically 0.1-100 mL volumes) in academia and industry. Despite their wide use in bioprocess development (i.e., process optimization and process validation), miniature process scouting devices (PSDs) are considered "black boxes" because they are generally not equipped with sensors. In this study, we show that on-line monitoring of dissolved oxygen (DO) and pH in a T-75 flask-based PSD can be achieved during cell passaging and that this information can be linked to different cellular metabolic states. In this case, on-line monitoring of DO and pH show three distinctive metabolic regions in passages 1-18, 19-28, 29-54 and in particular, the shift in the pH curve, the specific oxygen uptake rate (q(O2)), and the lactate production rate to the oxygen consumption rate yield (Y(Lac/ox)) confirm the existence of these distinctive metabolic regions. These findings are particularly useful because they show that sensor equipped PSDs can help to monitor cell culture behavior after thaw, in pre- and seed culture prior to scale-up and in development/optimization studies. Such routine monitoring will help to develop more consistent cell culture techniques.

Abstract
Stem cells have emerged as the starting material of choice for bioprocesses to produce cells and tissues to treat degenerative, genetic, and immunological disease. Translating the biological properties and potential of stem cells into therapies will require overcoming significant cell-manufacturing and regulatory challenges. Bioprocess engineering fundamentals, including bioreactor design and process control, need to be combined with cellular systems biology principles to guide the development of next-generation technologies capable of producing cell-based products in a safe, robust, and cost-effective manner. The step-wise implementation of these bioengineering strategies will enhance cell therapy product quality and safety, expediting clinical development.
