The requirements regarding the properties of fibres are closely linked to their further application. The demands for garment and home textile considerably differ from requirements for fibres that are used for technical purposes. This paper presents the results on investigation of raw flax and hemp fibres after their initial treatment with two step method (cold or hot alkaline, enzyme treatment and bleaching as after-treatment). The properties of hemp and flax fibres are evaluated by colorimetric analysis, mechanical testing, and microscopy of the surface of fibres.

Summary1. The effect of a standard, potent fibrinolytic enzyme therapy has been compared in fasting and lipemic dogs.2. The standard fibrinolytic regimen resulted in the complete dissolution of all clots produced experimentally in the fasting state in 10 dogs.3. Clots formed during alimentary lipemia exhibited a markedly increased resistance to the standard fibrinolytic regimen in 6 dogs.4. An increase in anti plasmin fibrinolytic titer with concomitant decrease in spontaneous fibrinolytic activity was observed in 15 dogs following the administration of a fatty meal. No difference in fibrinolytic activity and APF titer was demonstrable in fasting and lipemic blood samples obtained during fibrinolytic enzyme treatment.5. The possibility of the presence of specific inhibitors against the fibrinolytic enzyme in clots formed during lipemia has been investigated and the evidence to support this theory is discussed.

Enzyme Application

Eucalyptus wood chips were subjected to impregnation with various blends of novel fiber modify-ing enzymes before chemical pretreatment and two stages of refining using the preconditioning refiner chemical–alkaline peroxide mechanical pulping (PRC-APMP) process. Wood chip impregnation and pulp processing was con-ducted at a pilot plant in the United States. When compared under constant chemical application and at a constant 350 mL CSF, enzyme treatment reduced specific refining energy by at least 24%. The effect of one versus two stages of impregnation and of enzyme action upon several physical pulp properties was determined.

Secale Cereale L

The study describes sulfuric acid pretreatment of straw from Secale cereale L. (rye straw) to evaluate the effect of acid concentration and treatment time on the efficiency of biofuel production. The highest ethanol yield occurred after the enzyme treatment at a dose of 15 filter paper unit (FPU) per gram of rye straw (subjected to chemical hydrolysis with 2% sulfuric acid (SA) at 121 °C for 1 h) during 120 h. Anaerobic digestion of rye straw treated with 10% SA at 121 °C during 1 h allowed to obtain 347.42 L methane/kg volatile solids (VS). Most hydrogen was released during dark fermentation of rye straw after pretreatment of 2% SA, 121 °C, 1 h and 1% SA, 121 °C, 2 h—131.99 and 134.71 L hydrogen/kg VS, respectively. If the rye straw produced in the European Union were processed into methane, hydrogen, ethanol, the annual electricity production in 2018 could reach 9.87 TWh (terawatt-hours), 1.16 TWh, and 0.60 TWh, respectively.
