摘要： The presently claimed invention relates to a method for concentrating a beta-glucan comprising at least the following steps: (a1) contacting an aqueous beta-glucan solution having a concentration [c1] with at least one precipitating agent p1 to obtain a precipitated beta-glucan in a solvent mixture comprising water and the at least one precipitating agent p1; (b1) separating the precipitated beta-glucan from the solvent mixture comprising water and the at least one precipitating agent p1 to obtain a precipitated beta-glucan having a concentration [c2]; and (c1) applying force to the precipitated beta-glucan of (b1) to obtain a precipitated beta-glucan having a concentration [c3].

摘要： The presently claimed invention relates to a lubricant composition comprising at least one beta-glucan, optionally in form of one of its derivatives, at least one base oil, at least one additive component, and optionally water; the use of said lubricant compositions for reducing wear in metal-on-metal contact and the use of at least one beta-glucan for reducing the friction coefficient of a lubricant composition.
