Abstract
In vitro bioactivities of a β-glucan produced by Panebacillus polymyxa JB115 were investigated. Nitric oxide production by RAW 264.7 macrophage cells pre-treated with β-glucan JB115 (from 0.1 to 1 mg ml-1) was significantly increased, compared to that in untreated cells (P < 0.001). The β-glucan JB115 increased superoxide radical-scavenging activity by 66% at 1 mg ml-1. It also suppressed hyaluronidase (32%) and collagenase (33%) activities and, additionally, displayed antitumor activity, blocking the growth of Sarcoma 180 cells in a concentration-dependent manner. The immune-stimulatory, antioxidant, collagenase inhibitory and hyaluronidase inhibitory effects of the β-glucan support its potential role in the prevention of bacterial disease against fish and in the protection of skin against aging.
