aViscozyme L (Novozymes) added as percentage of product as supplied. EDTA was supplied as Mayoquest 200 with 38% EDTA and used to enzyme ret mature Ariane stems.
bEnzyme-retted straw passed through hand-card 2X and passed 1X through a Shirley Analyzer.
cAverage and standard deviation of 2 replicates of Shirley-cleaned fiber, with each replicate an average of 6 tests by Stelometer (force at break divided by weight by standard cotton testing).
dAverage and standard deviation of 2 replicates of Shirley-cleaned fiber, with each replicate an average of 2 tests by air flow using approximately 5 g based and IFC flax fiber standards for fineness (similar to methods used for cotton fineness).
