“…This is an area where further developments are likely. For example, adsorption of 2‐PE onto polymeric resins has been investigated with good results with S. cerevisiae (Carpiné et al, ; Hua et al, ; Mei et al, ). The results can probably be transferred easily to K. marxianus , provided there is biocompatibility of the adsorber material.…”

Kluyveromyces marxianus is emerging as a new platform organism for the production of flavour and fragrance (F&F) compounds. This food‐grade yeast has advantageous traits, such as thermotolerance and rapid growth, that make it attractive for cell factory applications. The major impediment to its development has been limited fundamental knowledge of its genetics and physiology, but this is rapidly changing. K. marxianus produces a wide array of volatile molecules and contributes to the flavour of a range of different fermented beverages. Advantage is now being taken of this to develop strains for the production of metabolites such as 2‐phenylethanol and ethyl acetate. Strains that were selected from initial screens were used to optimize processes for production of these F&F molecules. Most developments have focused on optimizing growth conditions and the fermentation process, including product removal, with future advancement likely to involve development of new strains through the application of evolutionary or rational engineering strategies. This is being facilitated by new genomic and molecular tools. Furthermore, synthetic biology offers a route to introduce new biosynthetic pathways into this yeast for F&F production. Consumer demand for biologically‐synthesized molecules for use in foods and other products creates an opportunity to exploit the unique potential of K. marxianus for this cell factory application.

“…It is known that processes used to recover coffee aromas in industries (Herrera et al, 1970;Nestec and Liu, 1986), boil down to wetting roast and ground coffee, but present the drawbacks of high-energy spending and the possibility of degradation of the compounds involved. Other alternatives for the recovery of coffee aroma have been investigated as adsorption (Canteli et al, 2014;Carpiné et al, 2013;Sacano et al, 1996Sacano et al, , 1999Zuim et al, 2011), supercritical extraction (Lucas and Cocero, 2006;Lucas et al, 2004), wet grinding (Baggenstoss et al, 2010), nanofiltration (Vincze and Vatai, 2004;Pan et al, 2013) and other membrane processes (Brazinha et al, 2015).…”

a b s t r a c tPervaporation experiments with PDMS membrane have been performed in a plate and frame module to investigate its ability to concentrate volatile compounds identified in an industrial soluble coffee solution. Eight compounds were chosen to depict key aroma of soluble coffee. The effect of feed flow rate, temperature and permeate pressure on the pervaporation performance has been analyzed. Concentration polarization phenomena was not identified in the feed flow rate studied. The temperature effect showed a good agreement with the nonlinear Arrhenius equation. The permeate pressure followed the solution-diffusion model behavior. Results showed that pervaporation is a promising alternative to concentrate aroma compounds from soluble coffee.

Newly emerged nanomaterials, such as graphene or carbon nanotubes, are of increasingly widespread importance in environmental remediation, especially in their ability to remove undesirable chemicals from hydrological systems. Despite recent advances, the high cost of these materials and the relative inability to regenerate them hinders their use at larger scales. While it is commonly held that adsorption in fixed bed processes is more efficient than in batch processes, the definition of efficiency needs to be examined closely. In this paper, we show that there exists a critical effluent concentration above which batch processes are more efficient than fixed bed processes from this perspective. This work proposes a simple method to choose either batch or fixed bed processes when the goal is to minimize the quantity of adsorbent needed to remove contaminants to below a specified threshold level. It also provides a systematic set of selfconsistency checks on experimental measurements that may be used for comparative studies of these methods.
