And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

The growth of cell and the biochemical component in mixotrophic cultivation were affected by luminance, which is beneficial to growth and accumulation of nutritive components of C. vulgaris. 2. Growth of C. vulgaris under different magnetic treatment The cultivation of C. vulgaris was undertaken with static magnetic treatment, cycle magnetic treatment and magnetized water treatment respectively.

自养状态下小球藻生长缓慢,生物量低,但蛋白质、叶绿素、不饱和脂肪酸都较丰富;异养培养可以大幅提高小球藻生长速率和生物量,脂肪含量很高,有利于亚麻酸的积累,但光照的缺乏使叶绿素和蛋白含量降低;兼养培养既有利于藻的生长,也能促进各种成分的积累。
