13. Pectinolytic Enzymes from Actinomycetes for the Degumming of Ramie Bast Fibers
Actinomycetes isolated from 10 different soil and compost samples were screened for production of pectinolytic enzyme activities when grown on pectin-containing solid and liquid media. Pectinolytic enzymes, detected by using plate diffusion tests with a medium containing ramie (Boehmeria nivea) plant material as the sole carbon source, were mainly pectate ly

14. Purification and characterization of an extracellular pectate lyase from an Amycolata sp.
The extracellular pectate lyase (EC 4.2.2.2) of a nonsporulating Amycolata sp. was purified to homogeneity by anion- and cation-exchange chromatographies followed by hydrophobic interaction chromatography. The enzyme cleaved polygalacturonate but not highly esterified pectin in a random endolytic transeliminative mechanism that led to the formation of a wide
