“…Each enzyme was added with the concentration of 0.30 v/v %, except for PAn (0.60 v/v %). Fibers were manually extracted according to De Prez et al [19] which enabled us to characterize the fiber extraction efficiency. Fibers were then chemically characterized by the gravimetric method.…”

“…Enzymatic treatments on green flax were performed as described in De Prez et al [19]. Prior to enzymatic treatment, flax stems of 25 cm were dried at 105 °C during 24 h. 50 g of dried flax stems were immersed in a 1 l enzyme formulation of pH 6.5 containing 25 mM ethylenediaminetetraacetic acid (EDTA disodium salt dihydrate, VWR) and 0.30 v/v % enzyme, with exception of PAn (0.60 v/v %) due to its lower solubility.…”

“…water treatment and EDTA treatment. Flax stems were treated with tap water at 40 °C during 24 h. EDTA treatment consisted of incubating the flax stems in an EDTA solution of 25 mM at pH 6.5 and 40 °C during 24 h. Subsequently, fibers were manually extracted as described in De Prez et al [19]. Each enzymatic treatment was performed in duplicate.…”

“…Fibers were manually extracted from the flax stems from top to bottom as stated in De Prez et al [19]. Manual extraction enables us to assign any changes in fiber characteristics to enzymatic treatment and minimizes fiber damage introduced by the mechanical action.…”

“…The time necessary for the extraction of fibers and the yield of long fibers are measured. Time efficiency (E t ), fiber efficiency (E f ) and the overall extraction efficiency (EE) or separation efficiency (E s ) can be determined according to the adjusted equations as described in De Prez et al [19]:Ef =Amount of long fibers extractedTotal amount of flax stemsEt =Amount of long fibers extractedTime needed for extraction*2EE = E s = E f *E t Where, “ amount of long fibers extracted” and “ total amount of flax stems” are expressed in weight (g), and “ time needed for extraction” in (min).

Highlights Enzymatic treatment of flax offers a valuable alternative for dew retting. Polygalacturonase combined with xylanase activity leads to a markedly chemical refining of flax fibers. Enhanced fiber extraction efficiency reached by applying enzyme combinations. Extraction efficiencies twice as high compared to green fibers by combining polygalacturonase and pectinmethylesterase.

The article evaluates the effectiveness of the use of Aquarin, sodium humate, Epin and Zircon in the production of flax products. The use of these preparations was studied for topdressing of plants during the growing season and in the process of retted stalks maturation. Topdressing of crops was carried out in the phase of “rapid growth”. The processing of the fiber flax ribbon was carried out on the fifth day after pulling. The greatest efficiency in spraying fiber flax crops and processing retted stalks was shown by the combined use of Aquarin and Humate “Fertility”. The combined treatment of crops with Aquarin and a humic preparation provided an increase in all production indicators: straw yield increased by 11.6 %, seeds by 24.8 %, retted stalks and fibers by 4.6-6.2 %, and scabbard fiber by 44 %. The treatment of flax ribbon with micronutrient fertilizer Aquarin together with Humate “Fertility” led to an increase in the fiber yield by 5.1 %, the long fiber yield by 2.4 %, and the fiber strength by 0.35 Dan. The data obtained make it possible to recommend the use of preparations both during the growing season and in the process of retted stalks maturing to increase the efficiency of fiber flax production.
