Abstract
|
|
|
|
In 12:12 hour light/dark cycle cultivation of D. salina 1650, maximum specific growth rate of 0.59 (1/day) and 0.35 (g-crude hydrocarbons/ℓ/day) were obtained. The cell growth was inhibited at above 15×10 exp (-4) (㎉/㎠/h) of light intensity in an outdoor cultivation. It was also showed that temperature is one of the critical growth parameters in the outdoor cultivation. The hydrocarbon production from D. salina 1650 seems to be partially growth related production process, and these algal hydrocarbons can be used for subsituting petroleum directly or through cracking processes. The value of weight fraction carbon of D. salina 1650 was similar to that of Botryococcus braunii and so was the hydrocarbon productivity.
