We performed biochemical, mechanical, structural analyses flax stems fibers derived from field‐grown transgenic...

Yarrowia lipolytica yeast are able to produce kynurenic acid-a very valuable compound acting as a neuroprotective and antioxidant agent in humans. The recent data proved the existence of kynurenine biosynthesis pathway this cells. Due fact, aim work was enhance acid production using crude glycerol soybean molasses cheap renewable carbon nitrogen sources. obtained results showed that Y. GUT1 mutants higher concentrations (from 4.5 mg dm-3 14.1 dm-3) than parental strain (3.6 supernatant...

In many studies, natural flax fibers have been proven to be resistant and surgically suitable. Genetically modified fibers, derived from transgenic expressing three bacterial genes for the synthesis of poly-3-hydroxybutyric acid (PHB), better mechanical properties than unmodified fibers. The aim this study was examine biocompatibility composites containing polyhydroxybutyrate producing (M50) control (wt-NIKE) plants in a polylactide (PLA) matrix rat Musculus latissimus dorsi. For purpose,...

Kynurenic acid (KYNA) is a compound derived from the tryptophan catabolic pathway. Antioxidant and neuroprotective properties have been confirmed for KYNA, which makes it an interesting important metabolite of biomedical significance. In present study, yeast Yarrowia lipolytica was tested KYNA biosynthesis. The results showed that Y. strain S12 able to produce in high concentrations (up 21.38 μg/ml culture broth 494.16 μg/g cell dry weight biomass) optimized conditions medium supplemented...

The modification of flax fibers to create biologically active dressings is undoubted scientific and practical interest. Flax fibers, derived from transgenic expressing three bacterial genes for the synthesis poly-3-hydroxybutyric acid (PHB), have better mechanical properties than unmodified fibers; do not show any inflammation response after subcutaneous insertion; a good in vitro vivo biocompatibility. aim this study was examine applicability composites containing genetically modified (M50)...

Kynurenic acid (KYNA) is a bioactive compound exhibiting multiple actions and positive effects on human health due to its antioxidant, anti-inflammatory neuroprotective properties. KYNA has been found have beneficial effect wound healing the prevention of scarring. Despite notable progress in research focused observed during last 10 years, KYNA's presence flax (

Although arbuscular mycorrhizal fungi (AMF) are known for their positive effect on flax growth, the impact of genetic manipulation in this crop mycorrhiza and plant performance was assessed first time. Five types transgenic that were generated to improve fiber quality resistance pathogens, through increased levels either phenylpropanoids (W92.40), glycosyltransferase (GT4, GT5), or PR2 beta-1,3-glucanase (B14) produce polyhydroxybutyrate (M50), used. Introduced modifications did not change...

Flax fibers have bioactive properties due to their biochemical composition. The quality of the is main parameter that determines application, and process obtaining has a crucial impact on composition fibers. Therefore, this study aimed enhance flax by optimizing hydrodynamic degumming decorticated fibers, both non-transgenic (Nike) transgenic (B14) with overexpression β-1,3-glucanase gene from potato, were obtained through nine processes varied in temperature, time, rinsing temperature....

There is a growing demand for high-quality natural fibers, including flax which possess bioactive compounds with antioxidant, antibacterial, and anti-inflammatory properties. Traditional methods like dew retting are commonly used fiber production, but alternative approaches sought enhanced quality. This study presents novel method involving cottonization to improve the quality of fibers obtained from low-quality decorticated fibers. The research evaluates enhancement through various stages...

Y. lipolytica remains a nonpathogenic, unconventional yeast, which can be applied for the production of bioactive compounds. Our previous study confirmed ability yeast Yarrowia to produce kynurenic acid (KYNA). Here, we investigated effectiveness KYNA in cultures cultivated medium containing honey various origin, used as source carbon and energy. It was evidenced that highest content culture broth (68 mg/L) biomass (542 mg/kg) obtained when chestnut used. The lipids amino acids composition...

Global warming and the reduction in our fossil fuel reservoir have forced humanity to look for new means of energy production. Agricultural waste remains a large source biofuel bioenergy Flax shives are product obtained during processing flax fibers. We investigated possibility using low-lignin biogas production, specifically by assessing impact CAD deficiency on biochemical structural properties shives. The study used genetically modified plants with silenced gene, which encodes key enzyme...

Abstract The high demand for new biomaterials makes synthesis of polyhydroxyalkanoates (PHA) in plants an interesting and desirable achievement. Production polymers is example application biotechnology improving the properties plants, e.g. industrial properties, but it can also provide knowledge about plant physiology metabolism. subject present study was industrially important plant: flax, Linum usitatissimum L., a fibre cultivar (cv Nike). In gene encoding PHA synthase from Pseudomonas...

Chronic ulcers are the main cause of morbidity and mortality, incidence chronic wounds is expected to increase given that people live longer there civil diseases.Much attention in treatment concerns a dressing involves wound cleansing, bacterial balance, exudate management local tissue environment.
