A facile route for concurrent fabrication and surface selective functionalization of cellulose nanofibers by lactic acid mediated catalysis

Scientific Reports, 2023
Celulose nanofibers are lightweight, recycable, biodegradable, and renewable. Hence, there is a great interest of using them instead of fossil-based components in new materials and biocomposites.

Transformation of hard pollen into soft matter

Nature Communications, 2020
Pollen is an abundant material; but, currently has limited applications. Here, the authors turn pollen grains into soft microgel by de-esterification of pectin molecules and explore the mechanical and structural changes of the pollen grains using ...

The Ectopic Expression of a Pectin Methyl Esterase Inhibitor Increases Pectin Methyl Esterification and Limits Fungal Diseases in Wheat

Molecular Plant-Microbe Interactions, 2011
Cell wall pectin methyl esterification can influence plant resistance because highly methyl-esterified pectin can be less susceptible to the hydrolysis by pectic enzymes such as fungal endopolygalacturonases (PG). Pectin is secreted into the cell wall in

De-esterification of cephalosporin para-nitrobenzyl esters by microbial enzymes.

The Journal of Antibiotics, 1976
Bacteria and actinomycetes were screened for esterase enzymes capable of removing the para-nitrobenzyl ester from cephalosporins. An esterase preparation from Bacillus subtilis was used to prepare cephalexin and 7-ADCA from the corresponding para-nitrobenzyl esters.

Rootstock effects on bitter pit incidence in ‘Honeycrisp’ apples are associated with changes in fruit’s cell wall chemical properties

Frontiers in Plant Science, 2022
Bitter pit (BP) is a physiological disorder of apples that often appears during or after cold storage. Despite being defined as a calcium deficiency disorder, BP is a complex process that is not only affected by the total Ca2+ content in the fruit but ...
