Abstract A novel sugarcane juice beverage was successfully produced by liquid fermentation of G. lucidum and homogenate process with selecting the day 10 fermentation broth as the raw materials. The beverage was evaluated for its sensory, nutritional and antioxidant activities. The results showed that the beverage by the G.lucidum fermentation was rich in polysaccharides, triterpenes, proteins, and flavonoids, which were all significantly higher than sugarcane juice, especially polysaccharides and triterpenoids. And the beverage could retain the sensory quality of sugarcane juice and could therefore be favored by the consumers. The in vitro antioxidant activity showed that the beverage had high scavenging and reducing abilities. DPPH and ABTS•+ radical scavenging rate of 1 mL fermented beverage were similar to 0.04 mg/mL VC, while the hydroxyl radical scavenging rate and reducing power of 1 mL of fermented beverage were similar to 1.68 mg/mL and 0.19 mg/mL VC, respectively. Taken together, the sugarcane juice fermented beverage was a natural flavor substances with high antioxidant activity and non-toxicity.

Release behaviors of arsenic (As) during pyrolysis of two Chinese coal gangues were studied in this report. The pyrolysis experiments were carried out in a temperature programmed tube furnace under N2 atmosphere with different temperature (200-1200 ºC), residence time (0-50 min), heating rate (10-50 ºC min-1) and N2 gas flow rate (100-500 cm3 min-1). The experiment results, under different pyrolysis conditions, indicate that the release ratio of As increases with increasing temperature, as well as residence time during pyrolysis of coal gangues. Besides that, higher heating rate during pyrolysis of coal gangues can stimulate the As release from coal gangue to some extent. The release ratio of As increases to a maximum and then decreases when the N2 gas flow rate is increased. The results imply that different modes of ocurrence of As exist in two coal gangues. The As release has positive relation with the volatile matter release. As is more easily released than coal gangue matrix during coal gangue pyrolysis.
