Quantitative analysis of cotton (Gossypium hirsutum) lint trash by fluorescence spectroscopy.

The presence of cotton plant botanical components, or trash, embedded in lint subsequent to harvesting and ginning is an important criterion in the classification of baled cotton by the U.S. Department of Agriculture Agricultural Marketing Service.

Flax-retting by polygalacturonase-containing enzyme mixtures and effects on fiber properties.

Enzyme-retting of flax was accomplished via individual treatment with four polygalacturonase (PGase) containing solutions of various fungal sources and the resulting fibers were characterized. The retting solutions were equilibrated to contain 2.19 U of PGase activity as determined via a dinitrosalicylic acid (DNS) reducing sugar assay.
