A novel treatment of biogas digestate waste for biochar production and its adsorption of methylene blue and malachite green in a binary system

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study presents a novel treatment of biogas digestate to produce biochar at processing temperatures of 500–700 °C. The resulting biochar was applied for the simultaneous removal of methylene blue (MB) and malachite green (MG) in a binary system.

Enrichment of Full AAV2 Using Multicolumn Countercurrent Solvent Gradient Purification (MCSGP)

open access: yesBiotechnology and Bioengineering, EarlyView.
The multicolumn countercurrent solvent gradient purification (MCSGP) method was evaluated as a method to enhance the separation of empty and full capsids during AAV2 purification. The results demonstrated an enrichment of full AAV2 particles using MCSGP.

The P134Q Sucrose Phosphorylase: Subtle Changes in the Catalytic Properties Benefit the Production of 2‐O‐α‐Glucosyl Glycerol

open access: yesBiotechnology and Bioengineering, EarlyView.
Production of the cosmetic ingredient 2‐α‐d‐glucosyl glycerol (2GG) by the Pro134Gln variant of sucrose phosphorylase from Bifidobacterium adolescentis is reported. The authors show with detailed characterization and hybrid kinetic modeling that the enzyme variant can improve the 2GG productivity of the biocatalytic process due to its increased ...

A novel multiparameter sensor for shake flask cultivations: Online biomass, dissolved oxygen, and fluorescence monitoring for comprehensive bioprocess characterization

open access: yesBiotechnology Progress, EarlyView.
Abstract Shake flasks are one of the most widely used cultivation vessels in biotechnological process development. To improve the process understanding, new technologies have been reported for online monitoring of different parameters like oxygen, pH, or biomass in the last couple of years.

Reactivity of δ‐Functionalized Para‐Quinone Methides in Nucleophilic Addition Reactions

open access: yesChemistry – A European Journal, EarlyView.
The reactivities of δ‐functionalized para‐quinone methides (pQMs) were characterized by kinetic studies of their reactions with carbanions in DMSO. Evaluating the second‐order rate constants (k2) by the Mayr‐Patz equation gave the electrophilicities E of pQMs.

A Hemispherical Photometric Integrator [PDF]

open access: yesJournal of the Optical Society of America, 1922
SYNOPSISA study of the errors in spherical photometry due to the presence of the lamps and screens in the Ulbricht sphere led to the development of a fixed convex mirror to be used in place of the two larger screens. A further development of the theory of interference within the instrument led to the adoption of a hemisphere in place of the complete ...
