The Hierarchical Structure of Sheep Wool and Its Impact on Physical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Sheep wool, a prevalent α‐keratinous fiber, is an essential model for studying protein‐based fibers. Its genetic diversity across breeds enables the establishment of multiscale structure‐property relationships, uncovering previously elusive insights into wool's hierarchical structure.

The relationships between microbiota and the amino acids and organic acids in commercial vegetable pickle fermented in rice-bran beds

open access: yesScientific Reports, 2021
The microbial community during fermented vegetable production has a large impact on the quality of the final products. Lactic acid bacteria have been well-studied in such processes, but knowledge about the roles of non-lactic acid bacteria is limited ...

Biosynthesis of Glutamic Acid [PDF]

open access: yes, 1964
An unknown microorganism was isolated from the soil by using defined selective medium. It could synthesize glutamic acid from glucose and urea. When subjected to repeated ultra-violet light and X-ray irradiations, and after process of screening, the ...

Conformational studies of various hemoglobins by natural-abundance 13C NMR spectroscopy [PDF]

open access: yes, 1972
Studies of variously liganded hemoglobins (both from human and rabbit) by natural-abundance 13C NMR spectroscopy have revealed apparent conformational differences that have been interpreted on the basis of two quaternary structures for the α2ß2 tetramer,
