Abstract
Aqueous Two-Phase Systems (ATPSs) have been extensively studied for their ability to simultaneously separate and purify active pharmaceutical ingredients (APIs) and key intermediates with high yields and high purity. Depending on the ATPS composition, it can be adapted for the separation and purification of cells, nucleic acids, proteins, antibodies, and small molecules. This method has been shown to be scalable, allowing it to be used in the milliliter scale for early drug development to thousands of liters in manufacture for commercial supply. The benefits of ATPS in pharmaceutical separations is increasingly being recognized and investigated by larger pharmaceutical companies. ATPSs use identical instrumentation and similar methodology, therefore a change from traditional methods has a theoretical low barrier of adoption. The cost of typical components used to form an ATPS at large scale, particularly that of polymer-polymer systems, is the primary challenge to widespread use across industry. However, there are a few polymer-salt examples where the increase in yield at commercial scale justifies the cost of using ATPSs for macromolecule purification. More recently, Ionic Liquids (ILs) have been used for ATPS separations that is more sustainable as a solvent, and more economical than polymers often used in ATPSs for small molecule applications. Such IL-ATPSs still retain much of the attractive characteristics such as customizable chemical and physical properties, stability, safety, and most importantly, can provide higher yield separations of organic compounds, and efficient solvent recycling to lower financial and environmental costs of large scale manufacturing.

Abstract
Liquid-liquid phase separation between aqueous solutions containing two incompatible polymers, a polymer and a salt, or a polymer and a surfactant, has been exploited for a wide variety of biotechnology applications throughout the years. While many applications for aqueous two-phase systems fall within the realm of separation science, the ability to partition many different materials within these systems, coupled with recent advances in materials science and liquid handling, has allowed bioengineers to imagine new applications. This progress report provides an overview of the history and key properties of aqueous two-phase systems to lend context to how these materials have progressed to modern applications such as cellular micropatterning and bioprinting, high-throughput 3D tissue assembly, microscale biomolecular assay development, facilitation of cell separation and microcapsule production using microfluidic devices, and synthetic biology. Future directions and present limitations and design considerations of this adaptable and promising toolkit for biomolecule and cellular manipulation are further evaluated.

Abstract
This review addresses whole cell separation and isolation using aqueous two-phase systems based on biocompatible polymers. The physicochemical factors that influence phase separation and systems properties are analysed. Especially, emphasis is given to the polyethylene glycol (PEG) and dextran two-phase systems and to stimuli-responsive soluble-insoluble polymers. The major factors that affect cell partitioning, such as polymer molecular weight and concentration, temperature, ionic species and pH, and affinity extraction, are also evaluated taking into account the cell types and cell surface properties. The applications of aqueous two-phase separation in cell processing are described, namely the new developments in continuous cell partitioning in microdevices and extractive bioconversions with relevance to the biomedical sector.

Abstract
Marine sponges are known to produce an overwhelming array of secondary metabolites with pharmaceutical potential. The technical and economical potential of using marine sponges for large-scale production of these compounds was assessed for two cases: the anticancer molecule halichondrin B from a Lissodendoryx sp., and avarol from Dysidea avara for its antipsoriasis activity. An economic and technical analysis was done for three potential production methods: mariculture, ex situ culture (in tanks), and cell culture. We concluded that avarol produced by mariculture or ex situ culture could become a viable alternative to currently used pharmaceuticals for the treatment of psoriasis. Production of halichondrin B from sponge biomass was found to not be a feasible process, mainly due to the extremely low concentration of the compound in the sponge. Technical feasibility was also analyzed for five alternatives: chemical synthesis, wild harvest, primmorph culture, genetic modification and semi-synthesis. It was concluded that the latter two approaches could prove to be valuable methods for the production of pharmaceuticals, based on chemical structures of secondary metabolites present in trace amounts in marine sponges.

Abstract
The low productivity of algal cultures in the production of high-value compounds is the most significant bottleneck for commercialization of this technology. Cultures in which cell mass is reused for continuous production are proposed as a solution to overcome this problem. Recently, a method was developed in which beta-carotene was harvested from the microalga Dunaliella salina grown in a two-phase bioreactor. This raises the question of whether this technique could also be used in the mass production of secondary metabolites. Understanding the mechanism of the milking process and its relationship to the product formation pathway should reveal whether other products can be milked from various species of microalgae.

Abstract
This review sums up the activity in the field of in situ product removal in whole cell bioprocesses over the last 20 years. It gives a complete summary of ISPR operations with microbial cells and cites a series of interesting ISPR applications in plant and animal cell technology. All the ISPR projects with microbial cells are categorized according to their products, their ISPR techniques, and their applied configurations of the ISPR set-up. Research on ISPR application has primarily increased in the field of microbial production of aromas and organic acids such lactic acid over the last ten years. Apart from the field of de novo formation of bioproducts, ISPR is increasingly applied to microbial bioconversion processes. However, despite of the large number of microbial whole cell ISPR projects (approximately 250), very few processes have been transferred to an industrial scale. The proposed processes have mostly been too complex and consequently not cost effective. Therefore, this review emphasizes that the planning of a successful whole cell ISPR process should not only consider the choice of ISPR technique according to the physicochemical properties of the product, but also the potential configuration of the whole process set-up. Furthermore, additional process aspects, biological and legal constraint need to be considered from the very beginning for the design of an ISPR project. Finally, future trends of new, modified or improved ISPR techniques are given.

Abstract
Plant cell suspension culture has become the focus of much attention as a tool for the production of secondary metabolites including paclitaxel, a well-known anticancer agent. Recently, it has also been regarded as one of the host systems for the production of recombinant proteins. In order to produce phytochemicals using plant cell cultures, efficient processes must be developed with adequate bioreactor design. Most of the plant secondary metabolites are toxic to cells at the high concentrations required during culture. Therefore, if the product could be removed in situ during culture, productivity might be enhanced due to the alleviation of this toxicity. In situ removal or extractive bioconversion of such products can be performed by in situ extraction with various kinds of organic solvents. In situ adsorption using polymeric resins is another possibility. Using the fact that secondary metabolites are generally hydrophobic, various integrated bioprocessing techniques can be designed not only to lower toxicity, but also to enhance productivity. In this article, in situ extraction, in situ adsorption, utilization of cyclodextrins, and the application of aqueous two-phase systems in plant cell cultures are reviewed.

Abstract
Commercial production of aroma compounds by de novo microbial biosynthesis has been principally limited by the low productivity so far achieved. Production of 6-pentyl-alpha-pyrone (6PP), a coconut-like aroma compound, by Trichoderma harzianum has been limited by the toxic effect that occurs even at low concentration (<100 ppm). This work evaluated the feasibility of the use of aqueous-two phase systems (ATPS), as in situ extraction systems, in order to overcome the toxic effects of 6PP and to improve culture productivity. The partition behaviour of 6-pentyl-alpha-pyrone and Trichoderma harzianum mycelium in polyethylene glycol (PEG)-salt and PEG-dextran two-phase systems was investigated and it is reported for the first time. The evaluation of system parameters such as PEG molecular mass, concentration of PEG as well as salt, volume ratio (Vr) and dextran molecular mass, was carried out to determine under which conditions the 6PP partitions to the opposite phase that mycelium does. PEG-dextran systems proved to be unsuitable for the in situ recovery of 6PP because either 6PP and biomass partitioned to the same phase or a large extraction phase was required for the process. ATPS extraction comprising Vr = 0.26, PEG 1450 (7.2% w/w) and sulphate (16.6% w/w) provided the best conditions for the maximum accumulation of the biomass into the bottom phase and concentrated the 6PP in the opposite phase (i.e. 86% of biomass and 56% of 6PP of the total amount loaded from the fermentation extract into the ATPS) for ex situ bioseparation. However, this system caused complete inhibition of the growth of the microorganism during the in situ bioseparation, probably as a consequence of the high ionic strength resulting from the salt concentration. Consequently, two ATPS PEG 8000-sulphate (12%/7% and 6%/14%) were evaluated and proved to be more suitable in the potential application for the in situ recovery of 6PP.

Abstract
This paper presents the evaluation of the potential use of aqueous two-phase systems (ATPS) for the recovery of 6-pentyl-alpha-pyrone (6PP) produced by Trichoderma harzianum. The partition behaviour of 6PP and Trichoderma harzianum mycelium (biomass) in polyethylene glycol (PEG)-salt (phosphate and sulphate) and PEG-dextran ATPS was investigated. The influence of defined system parameters (e.g. molecular mass of PEG and dextran, volume ratio, etc.) on the partition behaviour of 6PP and Trichoderma harzianum mycelium was evaluated to select under which conditions 6PP and mycelium partition to opposite phases. In PEG-dextran systems either large extraction phases were required or mycelium and 6PP partitioned to the same phase. ATPS comprising V(r)=0.23, PEG 8000 6.6% w/w and sulphate 14.0% w/w provided the best conditions to satisfy the process requirement of biomass accumulation into the bottom phase and 6PP concentration in the top phase.

Abstract
Although extractive bioconversions in aqueous two-phase systems (ATPSs) have been studied for over a decade, this has not yet resulted in widespread industrial application. The main reasons are the cost of the phase-forming polymers and the complexity of ATPS behavior. A number of recent developments may give a new impetus to this technology. First of all, the use of extractive bioconversions in ATPSs has recently been extended to high-value protein products, while in the meantime the development of low-cost ATPSs is ongoing. Furthermore, novel chromatographic methods enable the analysis of polymer and metabolite compositions in complex ATPS mixtures, and recently employed statistical experimental designs provide a tool for efficient data gathering, while they also reveal synergistic effects between process parameters. Together, these developments open the way towards improved modeling of partitioning behavior in ATPSs.

Abstract
A very wide range of methods has recently been employed to selectively partition fermentation products, substrates, or other metabolites to achieve an overall improvement in bioprocess performance. Techniques ranging from extraction and gas stripping to electrokinetic methods have been used to favorably influence the microenvironment of cells being cultivated in bioreactors. Virtually all types of cells, including animal cells, have benefitted by such selective partitioning and very high value fermentation products, such as monoclonal antibodies and secondary metabolites, have been produced using this process concept.
