For most aquacultured animals, the unsaturated fatty acids of marine microalgae have the effects of raising their rates of hatchability, survival and growth and the essential nutrients for the cultured animals such as fish and shrimp. Japanese and ROK scholars have reported that the algal powder added into the fish and shrimp bait may act as coagulating and anti-collapsing agents, and is especially effective if it is used in the water lacking minerals and vitamins[1]. Japanese scholars have p… 相似文献

超声波对球等鞭金藻脂肪酸组成的效应研究 总被引:3,自引:0,他引:3
EFFECTOFULTRASONICRADIATIONONTHEFATTYACIDCOMPOSITIONINIsochrysisgalbana一般来说,较低强度的超声波可以通过改进反应物的质量传输机制,提高酶的活性或加速细胞的新陈代谢过程[1]。国内一些学者研究表明,采用低功率超声辐照培养基,可提高藻类细胞的生长速率,从而提高这些细胞的蛋白质产量[2~4]。海洋生物活性物质的研究,是开发海洋生物资源的一个热点,在海洋单胞藻营养成分中,多不饱和脂肪酸(PUFA)是重要的生物活性物质。有关超声辐射法提高海洋单胞藻PUFA含量的研究尚未见有报道,如何通过改变… 相似文献
