“…3-Hydroxypropanal (I-5), otherwise known as lactaldehyde, is naturally produced from glycerol and is predominant in all living organisms including humans and bacteria [ 41 ]. The molecule (I-5) links with lactic acid production during fermentation [ 42 ]. The emergence of lactic acids as a product of this fermentation reflects the type of fermentation that occurred.…”

Chrysophyllum albidum Linn (African star apple) is a fruit with extensive nutritional and medicinal benefits. The fruit and kernel in the seed are both edible. Strains of lactic acid bacteria (LAB) were isolated from fermented seeds and assessed for probiotic characteristics. The extracts in both the unfermented and the fermented aqueous extracts from the kernels obtained from the seeds of C. albidum were subjected to analysis using the gas chromatography/mass spectrometry (GC-MS) method. This analysis identified the bioactive compounds present as possible substrate(s) for the associated organisms inducing the fermentation and the resultant biotransformed products formed. Three potential probiotic LAB strains identified as Lactococcus raffinolactis (ProbtA1), Lactococcus lactis (ProbtA2a), and Pediococcus pentosaceus (ProbtA2b) were isolated from the fermented C. albidum seeds. All strains were non hemolytic, which indicated their safety, Probt (A1, A2a, and A2b) grew in an acidic environment (pH 3.5) during the 48-h incubation time, and all three strains grew in 1% bile, and exhibited good hydrophobicity and auto-aggregation properties. Mucin binding proteins was not detected in any strain, and bile salt hydrolase was detected in all the strains. l-lactic acid (28.57%), norharman (5.07%), formyl 7E-hexadecenoate (1.73%), and indole (1.51%) were the four major constituents of the fermented kernel of the C. albidum, while 2,5-dimethylpyrazine (C1, 1.27%), 3,5-dihydroxy-6-methyl-2,3-dihydropyran-4-one (C2, 2.90%), indole (C3, 1.31%), norharman (C4, 3.01%), and methyl petroselinate (C5, 4.33%) were the five major constituents of the unfermented kernels. The isolated LAB are safe for consumption. The fermenting process metabolized C1, C2, and C5, which are possible starter cultures for the growth of probiotics. Fermentation is an essential tool for bioengineering molecules in foods into safe and health beneficial products.

“…Thus, can they be efficiently separated, and only miniscule quantities enter the esterification process. Similarly, lactic acid is relatively easily separated from acrylic acid, and its effect on esterification process can be neglected . All remaining impurities are either acids or alcohols and can through side reactions form esters with either acrylic acid or n -butanol.…”

“…The clustering reduces the number of components for further evaluation from 14 to 8 (Table ). The analysis determined that all but two components can be successfully removed from butyl acrylate. Butyl propionate has almost identical vapor pressure as butyl acrylate and cannot therefore be separated with distillation.…”

Biobased polymer molecules are a goal for the future. Here, the different intermediate pathways toward renewable structural constituents, which can substitute petrochemically derived unsustainable ones, are evaluated. Various biomass resources are covered, such as cellulose, hemicellulose, lignin, lipids, and proteins, as well as their building blocks, such as sugars, glycerol, or itaconic acid. Further emphasis is put on the impact of the impurities in the biobased monomers and the possible separations steps to remove them. The kinetics of the radical polymerization process of reacting acrylic monomers, methacrylic monomers, and styrene is reviewed. Classical elementary mechanisms are briefly discussed, while focus is put on secondary chemical reactions that influence rates greatly at elevated system temperatures, starved-feed conditions, and unideal-mixed reactor units. These functional measures have now become a common standard practice in resin production manufacturing. Described breaking/forming transformations are the styrene self-initiation step, macromonomer carrier propagation, backbiting, long chain branching, β-scission, and methacrylate continuous depropagation. The effect of the copolymerization on involved occurring changes is also overviewed. Likewise, functionality now plays a much greater role than it used to, is linked to final formulation characteristics, and is thus an integral related part of this theoretical methodology. Cross-linking mechanisms are briefly discussed. Last but not least, an insight into modeling is presented with an emphasis on lumping, the method of moments, Monte Carlo applications, and simulating conversions, as well as correlated molecular mass distributions.

“…Distillation has been commonly used in bio-based production processes, including the refining of biofuels and their derivatives [72][73][74][75][76][77]. In the area of bio-oil production, a distillation has been used in many studies.…”

“…In these examples vacuum conditions are used to lower the boiling point of bio-oil products, while in Silvestre et al [75] vacuum distillation was used to carry out a separation on a heat sensitive compound. Reactive distillation is another form of distillation that is employed in the separation of bio-based production processes [73,74,81], where reaction and distillation steps are combined in one column.…”

Abstract:Recovering valuable compounds from waste streams of bio-based production processes is in line with the circular economy paradigm, and is achievable by implementing "simple-to-use" and well-established process separation technologies. Such solutions are acceptable from industrial, economic and environmental points of view, implying relatively easy future implementation on pilot-and full-scale levels in the bio-based industry. Reviewing such technologies is therefore the focus here. Considerations about technology readiness level (TRL) and Net Present Value (NPV) are included in the review, since TRL and NPV contribute significantly to the techno-economic evaluation of future and promising process solutions. Based on the present review, a qualitative guideline for resource recovery from bio-based production processes is proposed. Finally, future approaches and perspectives toward identification and implementation of suitable resource recovery units for bio-based production processes are discussed.
