ABSTRACT
Microalgae is a single-cell organism with the characteristics of high light energy utilization rate, fast growth rate, high-value bioactive components and high energy material content. Therefore, microalgae has broad application prospects in food, feed, bioenergy, carbon sequestration, wastewater treatment and other fields. In this article, the microalgae biotechnology development in recent years were fully consulted, through analysis from the literature and patent. The progress of microalgal biotechnology at home and abroad is compared and discussed. Furthermore, the project layout, important achievements and development bottlenecks of microalgae biotechnology in our country were also summarized. At last, future development directions of microalgae biotechnology were discussed.

[Objective]To establish osteoarthritis model in rabbit knees by two kinds of surgery methods,and to explore their applicable conditions.[Method]Seventeen rabbits were divided into three groups(Hulth group,ligament-excised group and control group),they were anesthetized and operated differently according to their group.The rabbits were sacrificed at 1,3 and 6 weeks after surgery.The femoral condylars were harvested and studied in both gross morphological and pathohistological aspect.[Result]The degeneration of articular cartilage of the two surgery groups got worse by time,and their Mankin's scores were significantly higher than those in the control group(P
