In the investigation of a pathway for ethylene biosynthesis, intermediates arising from the metabolism of β-alanine-2-14C to ethylene by enzyme powders from wax-bean cotyledons were isolated and identified by paper and thin-layer chromatography. Quantitative determinations of the label have provided evidence for the conversion of β-alanine through malonic semialdehyde, β-hydroxypropionic acid, and acrylic acid to ethylene.

Hydroxypropionic Acid

3-hydroxypropionic acid is a commercially valuable, important platform chemical. It can serve as a precursor for several key compound, such as acrylic acid, 1,3-propanediol, methyl acrylate, acrylamide, ethyl 3-HP, malonic acid, propiolactone and acrylonitrile. Several microorganisms can produce through a range of metabolic pathways. It is indispensable for the commercial production of 3-HP to use cheap and abundant substrates and also to produce in highly efficient processes which could result high yield, titer and productivity. Because  of the fact, that natural microorganism do not perform these conditions, metabolic engineering and genetically engineered microorganism are widely used for research and production as well. Several metabolic pathways are introduced to utilize glucose or glycerol for 3-HP production. In this overview naturally producer microorganisms, synthetic biochemical pathways, results from the recent years and recovery of 3-HP are detailed.

Biocatalytic Process

A biocatalytic process for synthesis of acrylic acid was studied in the presence of Rhodococcus erythropolis 4-1 and Alcaligenes faecalis 2 strains with the pronounced amidase activity. The optimal pH of the process was 6–7 for R. erythropolis 4-1 and 7–7.5 for A. faecalis 2, optimal temperature 20–50 °C for both strains, optimal concentration of acrylamide 150 mM for R. erythropolis 4-1 and 250 mM for A. faecalis 2. At the stepwise addition of the substrate, the synthesis was more effective with A. faecalis 2 than with R. erythropolis 4-1. Freezing at –20 °C was shown preferable for storing the biocatalysts. The amidase activity of both humid and dry stored A. faecalis 2 cells immobilized on activated glutaric aldehyde and non-activated chitosan was not decreased.

Bacterial Cell Immobilization

Cells of amidase containing bacteria of Rhodococcus erythropolis 4-1 and Alcaligenes faecalis 2 were immobilized using carriers such as barium alginate, agarose, chitosan and κ-carrageenan. The aim of the work was to study the effect of bacterial cell immobilization methods on the operational stability of a bio-catalyst. It has been determined that the best carrier for the stable operation of the biocatalyst was aga-rose. The highest amount of acrylic acid was obtained during multi-cycle transformation of acrylamide by immobilized A. faecalis 2 cells.

Initiator System

Multifunctional nanoparticles have been shown earlier to bind certain proteins with high affinity and the binding affinity could be enhanced by molecular imprinting of the target protein. In this work different initiator systems were used and compared during the synthesis of poly (N-isopropylacrylamide-co-acrylic acid-co-N-tert-butylacrylamide) nanoparticles with respect to their future applicability in molecular imprinting of lysozyme. The decomposition of ammonium persulfate initiator was initiated either thermally at 60 °C or by using redox activators, namely tetramethylethylenediamine or sodium bisulfite at low temperatures. Morphology differences in the resulting nanoparticles have been revealed using scanning electron microscopy and dynamic light scattering. During polymerization the conversion of each monomer was followed in time. Striking differences were demonstrated in the incorporation rate of acrylic acid between the tetramethylethylenediamine catalyzed initiation and the other systems. This led to a completely different nanoparticle microstructure the consequence of which was the distinctly lower lysozyme binding affinity. On the contrary, the use of sodium bisulfite activation resulted in similar nanoparticle structural homogeneity and protein binding affinity as the thermal initiation.
