From green to circular chemistry paved by biocatalysis

Abstract

Since its origin, green chemistry has headed the best-guiding philosophy for reducing pollution and safeguarding the environment. The twelve Principles of Green Chemistry provide us with enough tools to design...

Polyphenol-Rich Extracts from Agroindustrial Waste and Byproducts: Results and Perspectives According to the Green Chemistry and Circular Economy

“…By integrating the principles of both approaches in the valorization of agroindustrial waste and byproducts, it is possible to create sustainable solutions to reducing environmental pollution and waste generation but also generate economic value by promoting resource efficiency and development of a circular economy. 235…”

Reutilization of the Most Stable Coimmobilized Enzyme Using Glutaraldehyde Chemistry to Produce a New Combi-biocatalyst When the Coimmobilized Enzyme with a Lower Stability Is Inactivated

“…The development of biocatalysis − and the focus on cascade reactions − have promoted a growing interest in the design of coimmobilized enzymes. − As the enzymes involved in the cascade are in a confined space after coimmobilization, this permits all coimmobilized enzymes to have available high concentrations of their substrates from the beginning of the reaction, avoiding the lag time usually found when utilizing independently immobilized enzymes. , When some intermediate product is unstable, this lag time can define the obtained yields and the level of contamination by the unwanted byproduct . Otherwise, enzyme coimmobilization mainly allows a reduction in the reaction cycle time, and this time saving may depend on the enzyme kinetic features and biocatalyst features …”

Carbonic anhydrase assisted acidogenic fermentation of forest residues for low carbon hydrogen and volatile fatty acid production: enhanced in situ CO2 reduction and microbiological analysis

“…22 CAs, which are ubiquitous enzymes are known to be highly prevalent among bacteria, archaea, and eukaryotes, wherein they are postulated to fulfill a multitude of roles. 24,25 CA serve as catalysts for the reversible hydration reaction of carbon dioxide (CO 2 ) into bicarbonate, accelerating the limiting step of CO 2 solubilization in aqueous media. 26,27 As such, CA has the potential to mitigate CO 2 levels in bioconversion processes resulting in elevated levels of CO 2 uptake by the microbes or enzymes and providing a viable carbon supply for the production of high-added value products, such as biofuels and chemicals.…”
