“…However, the selection of the organic solvent plays a major role as it may denature or inhibit the enzymes. Furthermore residues of organic solvents in the products are undesired as many solvents are not allowed in processing procedures due to their toxicity, limiting their use in pharmaceutical, food or personal care applications (Ran et al, 2008).…”

The aim of this work is to devise an efficient enzymatic process for the production of linear alkyl esters in aqueous miniemulsion systems. The esterification reactions of linear alcohols and carboxylic acids were performed with three different enzymes, commercial Amano lipase PS from Pseudomonas cepacia, Lipase type VII from Candida rugosa, and lyophilized Fusarium solani pisi cutinase expressed in Saccharomyces cerevisiae SU50. The miniemulsion system shows a high potential for the synthesis of linear alkyl esters, for example, hexyl octanoate, which could be synthesized with an ester yield of 94% using Amano lipase PS. Even with hydrophilic alcohols as ethanol, ethyl decanoate could be obtained with a concentration of 0.45 M and a yield of 62% using F. s. pisi cutinase as catalyst. High esterification rates for ethyl- and hexyloleate in miniemulsion showed a significant shift in cutinase selectivity towards longer chain length carboxylic acids. The stepwise addition of the alcohol led to an increase of the esterification yield. Moreover, increasing the amount of dispersed organic phase, mainly consisting of the substrates, led to a significant increase of the final ester concentration (e.g., concentration of 1.4 M for ethyl decanoate for the esterification with Amano Lipase PS).

Photobiocatalytic chemistry of oxidoreductases using water as the electron donor

et al. 2014

To date, water has been poorly studied as the sacrificial electron donor for biocatalytic redox reactions using isolated enzymes. Here we demonstrate that water can also be turned into a sacrificial electron donor to promote biocatalytic redox reactions. The thermodynamic driving force required for water oxidation is obtained from UV and visible light by means of simple titanium dioxide-based photocatalysts. The electrons liberated in this process are delivered to an oxidoreductase by simple flavin redox mediators. Overall, the feasibility of photobiocatalytic, water-driven bioredox reactions is demonstrated.

“…Production of PHA by transgenic plant may be economically viable if efforts are concentrated at improving this process. It may be possible in the near future to see farmers growing plastics in their field and a new agricultural product 'plastics fruit' may appear in our market by transgenic plants [250][251][252].…”

The last century witnessed the emergence of polymer science and technology that enabled the generation of knowledge and techniques to control the size, shape, structure, properties and functions of polymers to generate polymers with unprecedented properties and functions. There have been many attempts to apply this information to natural monomers and polymers to achieve the desired property profiles with varying degrees of success which have given/are giving it a new outlook as a possible alternative source for the production of polymers. Novel concepts and techniques such as 'bio-inspired' polymer design, 'synthetically-inspired' material development, etc., are contributing to the development of natural monomers and polymers as a sustainable resource to generate a knowledge-based design methodology to meet the vastly developing requirements of modern materials. This paper reviews these emerging concepts and techniques that integrate materials synthesis, process and manufacturing options with eco efficiency.
