Metabolites recovery from fermentation broths via pressure-driven membrane processes

The production of specific metabolites using microorganism has been promoted and enhanced by two different approaches, such as modification of the metabolic pathways of microorganism and optimization of culture medium conditions to synthesize specific compounds. However, research community is today focused on the development of processes and techniques for a suitable recovery of metabolites from different stages of fermentation. For this purpose, the use of organic solvents has been the most common approach for the recovery of specific target compounds according to the solvent affinity. Additionally, these techniques also require the implementation of unit processes to obtain better recovery rates; it means that solvent extraction methods need the implementation of additional steps to recover the solvents used, which may involve the increase of final costs in the production process. For this reason, researchers have started to consider membrane-based technologies (e.g. microfiltration [MF], ultrafiltration [UF], and nanofiltration [NF]), as an alternative for the recovery of metabolites from fermentation broths. Therefore, the objective of this paper is to provide an overview of the current findings of the recovery of metabolites from fermentation broths by means of pressure-driven membrane processes. Particular attention will be paid to relevant data, analyzing and discussing according to the membrane features, metabolite properties, and some other phenomena that influence in the separation. Moreover, a framework of the application of the MF, UF, and NF processes in solutes recovery is addressed. Finally, some fundamentals of these processes are also given.

Glass-forming ability of butanediol isomers

In this study, the thermal behavior of butanediol isomers is investigated for temperatures ranging from 103 to 303 K using differential scanning calorimetry, complemented, when necessary, by polarized light thermal microscopy. The butanediol isomers display quite different thermal behaviors: for 1,2- and 1,3-isomers, glass transition is the only thermal event observed; for 1,4-butanediol, crystallization occurs on cooling even at a high scanning rate and no glass formation was detected; and for the 2,3-isomer, glass or crystal formation is dependent on the experimental conditions employed. The glass-forming ability of the isomers is correlated with data available on their molecular symmetry.

MACROCYCLES IN THE CONSTRUCTION OF ACYCLIC STEREOCHEMISTRY

Cooperativity in chiroptical sensing with dendritic zinc porphyrins

Zinc porphyrin-appended dendrimers, 12PZn, 18PZn, 24PZn, and 36PZn, containing 12, 18, 24, and 36 zinc porphyrin units, respectively, were synthesized using zinc porphyrin dyad (2PZn) and triad (3PZn) as precursors. Although these dye-functionalized dendrimers all serve as chiroptical sensors for an asymmetric bipyridine (RR- and SS-Py2), the sensing capability is highly dependent on the structure of the dendritic scaffold. 2PZn, which is chiroptically silent toward Py2, turns cooperative and displays a large ICD (induced circular dichroism) response in the visible region when incorporated into 12PZn. Judging from the extents of contribution of each zinc porphyrin unit to the CD amplitudes ([Deltaepsilonmax]), the cooperativity in 24PZn (112 M-1 cm-1) is lower than that in 12PZn (196 M-1 cm-1) and much lower in dendron 4PZn (59 M-1 cm-1). In contrast, 3PZn, which is ICD-active toward Py2, hardly shows such an enhanced cooperativity when incorporated into 18PZn and 36PZn and dendron 6PZn, as well. Absorption spectroscopy suggests some unique conformational characteristics of the zinc porphyrin units in highly cooperative 12PZn. Copyright

Mechanistic Studies of Diastereoselective Cyclopropanation via Homochiral Ketals. 2. Studies with Conformationally Restricted 2-Cyclohexen-1-one Ketals

The effect of cyclohexene ring conformation on the diastereoselectivity observed for Simmons-Smith cyclopropanation of 2-cyclohexen-1-one ethylene ketals was examined by using (5S)-5-tert-butyl-2-cyclohexen-1-one 1,2-ethanediol, (2R,3R)-2,3-butanediol, and (2S,3S)-2,3-butanediol ketals.Reagent chelation by the pseudoequatorial dioxolane oxygen atom was shown to result in more effective methylene transfer.This regiochemical preference can either antagonize or reinforce diastereoselectivity due to steric hindrance of the dioxolane oxygen atoms from dissymmetric placement of methyl appendages on the dioxolane ring.
