Promotion of germination and shoot elongation of some plants by alginate oligomers prepared with bacterial alginate lyase


Promotion of germination and shoot elongation of some plants by alginate oligomers prepared with bacterial alginate lyase



Journal of Fermentation and Bioengineering 75(1): 68-70



DOI: 10.1016/0922-338x(93)90181-7

Depolymerization of sodium alginate (average molecular weight: 25,700) from an edible seaweed Eisenia bicyclis with bacterial alginate lyase yielded oligosaccharide(s) with an average molecular weight of 1,800 together with other components. The proliferation and/or differentiation of plants was markedly enhanced in the presence of the oligosacccharide(s), although that of mammalian (HeLa) cells and an algae (Chlamydomonas sp.) was not. The results indicate that the depolymerization products of alginate containing oligosaccharide-like compounds specifically affect the proliferation and/or differentiation of higher plants.
