Abstract
Inherently occurring foam formation during aerobic fermentations of surface-active compounds can be exploited by fractionating the foam. This also serves as the first downstream processing step for product concentration and is used for in situ product recovery. Compared to other foam prevention methods, it does not interfere with fermentation parameters or alter broth composition. Nevertheless, parameters affecting the foaming behaviour are complex. Therefore, the specific foam fractionation designs need to be engineered for each fermentation individually. This still hinders a widespread industrial application. However, few available commercial approaches demonstrate the applicability of foam columns on an industrial scale. This systematic literature review highlights relevant design aspects and process demands that need to be considered for an application to fermentations and proposes a classification of foam fractionation designs and methods. It further analyses substance-specific characteristics associated with foam fractionation. Finally, solutions for current challenges are presented, and future perspectives are discussed.

Abstract
Laccases have received the attention of researchers in the last few decades due to their ability to degrade phenolic and lignin-related compounds. This study aimed at obtaining the highest possible laccase activity and evaluating the methods of its purification. The crude laccase from bioreactor cultivation of Cerrena unicolor fungus was purified using ultrafiltration, aqueous two-phase extraction (ATPE) and foam fractionation (FF), which allowed for the assessment of these three downstream processing (DSP) methods. The repeated fed-batch cultivation mode applied for the enzyme production resulted in a high laccase specific activity in fermentation broth of 204.1 U/mg. The use of a specially constructed spin filter inside the bioreactor enabled the integration of enzyme biosynthesis and biomass filtration in one apparatus. Other methods of laccase concentration and purification, namely ATPE and FF, proved to be useful for laccase separation; however, the efficiency of FF was rather low (recovery yield of 24.9% and purification fold of 1.4). Surprisingly, the recovery yield after ATPE in a PEG 6000-phosphate system in salt phase was higher (97.4%) than after two-step ultrafiltration (73.7%). Furthermore, it was demonstrated that a simple, two-step purification procedure resulted in separation of two laccase isoforms with specific activity of 2349 and 3374 U/mg. All in all, a compact integrated system for the production, concentration and separation of fungal laccases was proposed.

Abstract
AbstractIn this paper, a single-/dual-stream foam separation device was constructed to simplify the conventional foam fractionation process (CFFP), by minimizing interactions between bubbles. This was expected to help reveal mechanisms in a ‘neat’ way. Results have shown negligible productivity of single-stream foam fractionation (SSFF) for the protein enrichment ratio (E) under conditions tested, whereas dual-stream foam fractionation (DSFF) was established as a reasonable basic unit of CFFP. The influence of DSFF operating conditions, such as the inlet protein concentration and gas velocity, were examined. Calculations of protein concentration and liquid volume were performed via foam thickness measurement, which is very difficult with CFFP. It was evident that the middle drainage channel played a key role in enrichment phenomena. The current DSFF system provides a control case for evaluating principles of foam fractionation. Furthermore, a simple mass-balance model has been proposed to represent the column-wide behavior of DSFF.

Abstract
Abstract
Foam fractionation process for concentration of laccases from two Basidiomycete strains under different process conditions was investigated. Culture supernatants of Cerrena unicolor and Pleurotus sapidus containing active laccase were used with and without surfactant additives. Two surfactants: cationic cetrimonium bromide (CTAB) and non-ionic Polysorbate 80 were applied in the range from 0.2 mM to 1.5 mM. The pH levels ranging from 3 to 10 were examined with particular attention to pH=4, which is close to the pI of the enzymes. Results show that the source of the enzyme is significant in terms of partitioning efficiency in a foam fractionation process. Laccase from Cerrena unicolor showed the best activity partitioning coefficients between foamate and retentate of almost 200 with yields reaching 50% for pH 7.5 and concentration of CTAB cCTAB = 0.5 mM, whereas laccase from Pleurotus sapidus showed partitioning coefficients of up to 8 with 25% yield for pH 4 and cCTAB = 0.5 mM.

Abstract
A laccase of the basidiomycete Pleurotus pulmonarius (PpuLcc) possessed strong decolorizing abilities towards artificial and natural dyes. The PpuLcc was purified from the culture supernatant via FPLC, and the corresponding gene cloned and expressed in Pichia pastoris GS115. To examine the impact of the C-terminal tail region and the signal peptide on the recombinant expression of PpuLcc, a non-modified version or different truncations (-2, -5, -13 AA) of the target protein were combined with different secretion signals. Heterologous expression of codon optimized constructs resulted in extracellular activities of the PpuLcc variants of up to 7000 U L-1 (substrate ABTS) which was six times higher than non-codon optimized constructs. In contrast to previous works, altering the C-terminal end of the protein did not influence kinetic parameters or the rate of expression. The His-Tag purified enzymes showed high temperature optima (50-70 °C) and thermo stability. All of the recombinant variants degraded triarylmethane and azo dyes. Rapid bleaching of β-carotene (E 160a) and the polyene acid norbixin (E 160b) using a laccase was found for the first time. Thus, the enzyme may be useful in decolorizing unwanted polyene pigments, for example from the processing of cheese, bakery, desserts, ice cream or coloured casings.

Abstract
For the production of bio active compounds, e.g., active enzymes or antibodies, a conserved purification process with a minimum loss of active compounds is necessary. In centrifugal partition chromatography (CPC), the separation effect is based on the different distribution of the components to be separated between two immiscible liquid phases. Thereby, one liquid phase is kept stationary in chambers by a centrifugal field and the mobile phase is pumped through via connecting ducts. Aqueous two phase systems (ATPS) are known to provide benign conditions for biochemical products and seem to be promising when used in CPC for purification tasks. However, it is not known if active biochemical compounds can "survive" the conditions in a CPC where strong shear forces can occur due to the two-phasic flow under centrifugal forces. Therefore, this aspect has been faced within this study by the separation of active laccases from a fermentation broth of Pleurotus sapidus. After selecting a suitable ATPS and operating conditions, the activity yield was calculated and the preservation of the active enzymes could be observed. Therefore, CPC could be shown as potentially suitable for the purification of bio-active compounds.

Abstract
Macrophomina phaseolina was cultivated in complex and simple media for the production of extracellular lipolytic enzymes. Culture supernatants were batch foam fractionated for the recovery of these enzymes, and column design and operation included the use of P 2 frit (porosity 40 to 100 μ m), air as sparging gas at variable flow rates, and Triton X-100 added at the beginning or gradually in aliquots. Samples taken at intervals showed the progress of the kinetic and the efficiency parameters. Best results were obtained with the simple medium supernatant by combining the stepwise addition of small amounts of the surfactant with the variation of the air flow rates along the separation. Inert proteins were foamed out first, and the subsequent foamate was enriched in the enzymes, showing estimated activity recovery (R), enrichment ratio (E), and purification factor (P) of 45%, 34.7, and 2.9, respectively. Lipases were present in the enriched foamate.

Abstract
A laccase (Lcc1) from the white-rot fungus Meripilus giganteus was purified with superior yields of 34% and 90% by conventional chromatography or by foam separation, respectively. Size exclusion chromatography (SEC) and sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE) yielded a molecular mass of 55 kDa. The enzyme possessed an isoelectric point of 3.1 and was able to oxidize the common laccase substrate 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) at a pH of 2.0, whereas the enzyme was still able to oxidize ABTS and 2,6-dimethoxyphenol (DMP) at pH 6.0. Lcc1 exhibited low K ( m ) values of 8 μM (ABTS) and 80 μM (DMP) and remarkable catalytic efficiency towards the non-phenolic substrate ABTS of 37,437 k (cat)/k (m) (s(-1) mM(-1)). The laccase showed a high stability towards high concentrations of various metal ions, EDTA and surfactants indicating a considerable biotechnological potential. Furthermore, Lcc1 exhibited an increased activity as well as a striking boost of stability in the presence of surfactants. Degenerated primers were deduced from peptide fragments. The complete coding sequence of lcc1 was determined to 1,551 bp and confirmed via amplification of the 2,214 bp genomic sequence which included 12 introns. The deduced 516 amino acid (aa) sequence of the lcc1 gene shared 82% identity and 90% similarity with a laccase from Rigidoporus microporus. The sequence data may aid theoretical studies and enzyme engineering efforts to create laccases with an improved stability towards metal ions and bipolar compounds.

Abstract
The empirical models developed through two independent RSM (RSM-I, 2(3); RSM-II, 2(5)) in terms of effective operational factors of inoculum age, inoculum volume, wheat bran-to-moisture ratio (RSM-I) and contact time, extraction temperature, agitation, fermented bran-to-solvent ratio and SDS (RSM-II) were found adequate to describe the optimization of exo-polygalacturonase from Bacillus subtilis RCK under solid-state fermentation (SSF) conditions. Through the analysis of RSM-I, wheat bran-to-moisture ratio and inoculum volume were found to be the most significant factors and an increment in both had a positive effect in enhancing enzyme yield, while in RSM-II all the factors significantly affected enzyme recovery except fermented bran-to-solvent ratio, which had the least impact within the ranges investigated in enhancing enzyme recovery. Based on contour plots and variance analysis, optimum operational conditions for maximum exo-polygalacturonase yield were achieved when 1.5% (v/w) of 24h old (OD(600 nm) approximately 2.7+/-0.2) B. subtilis RCK cells were inoculated on moistened wheat bran (1:7 solid substrate-to-moisture ratio) and enzyme was harvested by addition of solvent (1:6 fermented bran-to-solvent ratio) under shaking conditions (200 rpm) in presence of SDS (0.25% w/v) for 15 min at 35 degrees C. An over all 3.4 fold (1.7-fold RSM-I; 2.0 fold RSM-II) increase in enzyme production was attained because of optimization by RSM.
