Xylanases as a tool for the production of novel phytopharmaceuticals
2005 (English)In: NutraCos, ISSN 1720-4011, Vol. 4, no 2, p. 17-21Article in journal (Refereed) Published
Abstract [en]

Results are presented of a study on the production and biological activities of acidic and feruloyl oligosaccharides from xylan by family 10 and 11 endoxylanases [endo-1,4-β-xylanase] from Thermoascus aurantiacus and Sporotrichum thermophile [Myceliophthora thermophila]. Both family 10 and 11 endoxylanases were able to release branched xylooligosaccharides from xylan. Feruloyl oligosaccharides acted as antioxidants and showed protective effects against copper-catalysed peroxidation of low-density lipoproteins. Acidic xylooligosaccharides, products of 4-O-methyl-D-glucurono-D-xylan hydrolysis, functioned as plant growth regulators and antibacterial agents. Aldotetrauronic acid induced callus and somatic embryogenesis in culture explants of common mallow (Malva sylvestris) and cotton (Gossypium hirsutum). Aldopentauronic acid caused an increase in both the number of regenerants and their fresh weight to cucumber (cultivars Stella and Gilda) liquid culture in plant airlift bioreactors. Both acidic xylooligosaccharides were active against Bacillus cereus, Micrococcus flavus and Helicobacter pylori.
