布朗葡萄藻在不同培养基中的生长效应

研究了布朗葡萄藻(Botryococcus braunii)764株和765株在3种培养基Chu10、Chu13×2和SE中的生长效应.结果表明:(1)B.braunii764在Chu10中的细胞密度、生物量、总脂含量和总烃含量均高于Chu13×2和SE;B.braunii765在Chu10中的细胞密度、生物量和总脂含量高于Chu13×2和SE,而总烃含量在Chu13×2中较高.(2)B.braunii764的总脂和总烃含量分别为19.4%、23.4%,显著高于B.braunii765.

Effects of different culture medium on two Botryococcus braunii

Growth of Botryococcus braunii 764 and Botryococcus braunii 765 that were cultured in three media (Chu10, Chu13×2 and SE) was studied and compared. Cell density (OD₆₈₀), biomass(dry weight), total lipids, and total hydrocarbons were measured. The following results were reported:(1) total lipids and total hydrocarbons of B. braunii 764 were 19.4% and 23.4% respectively, which were significantly higher than those of B. braunii 765; (2) cell density, biomass, total lipids and total hydrocarbons of B. braunii 764 that was cultured in medium Chu10 were higher than those cultured in media Chu13×2 and SE, whereas only cell density, biomass and total lipids of B. braunii 765 cultured in medium Chu10 were higher than those cultured in Chu13×2 and SE, total hydrocarbons in Chu13×2 was higher than those in Chu10 and SE.
