Developments in the offshore seaweed feedstock bio-refinery model

Graphical abstract green chem algae biorefineryThe land use issues associated with biomass production points to marine biomass as a promising alternative. Seaweed is a rich resource, abundant in the world’s oceans. In addition to its potential for biofuel production, it is also important to obtain a stream of renewable chemicals from any seaweed bio-refinery to create an economically viable and sustainable process.

The present development, led by an Indian research team prominent in this field, creates a valuable side stream of chemical products to supplement the production of bio-ethanol from cellulose. Lipids, pigments and agar are all obtainable from the red algae feedstock by way of sequential extraction processes that improves the quality of the agar produced and significantly reduces the amount of auxiliary chemicals required compared to previous methods.

Thin film approach to biocatalysis

Chemistry World article written by Debbie Houghton

This lipase is one of the most largely employed enzymes in industry © Valerio Ferrario

Taking an unconventional approach to biocatalysis has allowed scientists in Italy to improve enzyme recyclability with a solvent-free reaction mixture. And by emphasising a need to design processes, biocatalysts and reactors together, instead of separately, they hope to widen the industrial applications of nature’s catalysts.

Lucia Gardossi, from the University of Trieste in Italy, has been investigating solvent-free reaction mixtures, which appeal to industry because of their comparably small production volumes and lack of organic solvents to dispose of. Although their efficiency and selectivity are attractive, biocatalysed versions of industrial reactions are rarely economically viable. The typically viscous reaction mixtures require vigorous mixing, which damages the enzymes and limits their recyclability.

His interests range from the certification and application of bio-based products, to the understanding of solvent effects in organic synthesis.

One pot enzymatic catalysis for the synthesis of chiral alkaloidsOpen access communication: One-pot triangular chemoenzymatic cascades for the synthesis of chiral alkaloids from dopamine

Researchers at UCL, UK, have developed a novel use of one-pot, multi-step enzymatic catalysis for the synthesis of chiral alkaloids. Transaminase (TAm) and norcoclaurine synthase (NCS) were employed as catalysts. In the synthesis of the tetrahydroprotoberberine product two carbon-carbon bonds are created under mild conditions with good enantiomeric purity (ee >95%), all in a short duration (3.5 hours).

The successive Pictet-Spengler cyclisation reactions provide an atom economic approach and high enantioselectivity to the formation of this valuable class of products. The authors of this work recognise the “remarkable potential of in vitro biocatalysis for the formation of complex chiral compounds“, which is increasingly important to contemporary green chemistry.

Versatile chemical intermediate produced renewably using heterogeneous catalyst

James Sherwood is a guest web-writer for Green Chemistry. James is a research associate in the Green Chemistry Centre of Excellence at the University of York. His interests range from the certification and application of bio-based products, to the understanding of solvent effects in organic synthesis.

Bio-based acetaldehyde graphical abstractEfficient and selective conversion of lactic acid into acetaldehyde using a mesoporous aluminum phosphate catalyst

Acetaldehyde is needed by the chemical industry for many diverse applications, such as paint and cosmetic formulations, plastics and construction materials. As such there is a need for renewable acetaldehyde within the bio-based economy and bio-ethanol can be oxidised to give acetaldehyde for this purpose. Now an alternative process using lactic acid as a feedstock has been developed.

The catalyst for this transformation is a mesoporous aluminium phosphate, facilitating full conversion of the lactic acid and yields of acetaldehyde exceeding 90%. While the use of aluminium is very favourable compared to ethylene oxidation catalysts based on silver for example, the longevity of phosphorus reserves are a concern. However the catalyst is robust and can be used for over 200 hours. Also, the process is efficient at lower temperatures than are often needed for transformations of lactic acid.

A greener recipe for copper nanowires – GC article in Chemistry World

Written by William Bergius

In an ingenious application of food chemistry more commonly associated with the searing of steak or baking of bread, scientists in Singapore have developed a green synthesis for well-defined copper nanowires (CuNWs).

Indium tin oxide (ITO) is the most widely used transparent conductor in today’s consumer technology, featuring in solar cells, touch screens and LED displays. However, alternatives are being sought due to the high cost and finite supply of indium. Films made from silver or copper nanowires are promising candidates, exhibiting high conductivity and optical transparency in addition to being flexible….
