A beta-1,3-xylanase-producing bacterium, Alcaligenes sp. XY-234, was isolated from the marine environment. The organism produced endo-1,3-beta-xylanase at a high level in the culture fluid. The enzyme was purified 292-fold by ammonium sulfate precipitation and several column chromatographies. The final enzyme preparation appeared to be homogeneous on disc(More)
 Some species of Spirogyra form rosette-shaped or rod-shaped rhizoids in the terminal cell of the filaments. In the present study, we analyzed an involvement of microtubules (MTs) in rhizoid differentiation. Before rhizoid differentiation, cortical MTs were arranged transversely to the long axis of cylindrical cells, reflecting the diffuse growth. At the(More)
