Characterization and flocculation mechanism of an alkali-activated polysaccharide flocculant from Arthrobacter sp. B4.

The characterization and flocculation mechanism of a bioflocculant produced by Arthrobacter sp. B4 were investigated. The bioflocculant's active ingredient was a polysaccharide (B4-PS) that consisted of three main fractions corresponding to the molecular weights of approximately 3.

Production, purification, and antibiofilm activity of a novel exopolysaccharide from Arthrobacter sp. B4.

A novel exopolysaccharide (EPS), namely, B4-EPS, is produced by Arthrobacter sp. B4. Response surface methodology (RSM) was employed to optimize the fermentation medium for increasing B4-EPS production.
