A strain Botryococcus braunii Kütz. that produces high levels of branched hydrocarbons (botryococcenes) was grown under different environmental conditions to investigate the relationship between growth and hydrocarbon production. Carbon dioxide concentration had the most significant influence on growth; 0.3% CO2‐enriched cultures demonstrated a minimum mass doubling time of ca. 40 h, compared to ca. 6 days for ambient air cultures grown on the same buffered growth medium. The botryococcene… Expand
Effects of carbon source on growth and morphology of Botryococcus braunii
TLDR
Growth was promoted substantially following exposure of the algae to glucose or mannose under light exposure, and cell and colony size, and the intracellular granules containing oil, were markedly larger than those cultured without glucose. Expand
Hydrocarbon production by the yayoi, a new strain of the green microalgaBotryococcus braunii
The Yayoi, a new strain of the green colonial microalgaBotryococcus braunii, was cultured with aeration of 2% CO2-enriched air. The final algal concentration on the basis of dry weight reached 1.9Expand
Culture of the hydrocarbon producing microalga Botryococcus braunii strain Showa: optimal CO2, salinity, temperature, and irradiance conditions.
TLDR
It is concluded that more efficient hydrocarbon production by the mass culture of strain Showa can be achieved by maintaining higher specific growth rate based on the culture conditions presented in this study. Expand
Growth and hydrocarbon production of microalga Botryococcus braunii in bubble column photobioreactors.
TLDR
Hydcarbon production kinetics of this alga in the linear growth phase was found to be growth-associated irrespective of the experimental conditions of illumination and preculture. Expand
Ether lipid production in relation to growth in Botryococcus braunii
Abstract A strain of Botryococcus braunii (A race) that synthesizes large amounts of an ether lipid mixture (botryococcoid ethers), dominated by a C54H100O2 compound, was grown in batch air-liftExpand
Continuous culture of hydrocarbon-rich microalga Botryococcus braunii in secondarily treated sewage
TLDR
STS would appear to suffice as an appropriate medium for continuously sustainable growth of B. braunii and the algal consumption of nitrate and phosphate should help in removing these ions from STS. Expand
Changes in the hydrocarbon-synthesizing activity during growth of Botryococcus braunii B70.
TLDR
The high activity of pentose phosphate pathway in the early logarithmic growth was seemed to be the contribution of the supply of NADPH for botryococcene synthesis. Expand
Hydrocarbon production in high density Botryococcus braunii race B continuous culture
TLDR
A steady increase in photobioreactor conductivity was revealed suggesting an accumulation of ions may be the reason for rapid culture crash and washout observed at all dilution rates after several months of continuous operation. Expand
Optimal Culturing and Enhancement of Lipid Accumulation in a Microalga Botryococcus braunii
TLDR
Experiments for varied media compositions revealed that the accumulation of lipid was the highest at 48% (dry cell weight based) in the nitrogen deficient medium and its corresponding specific growth rate was comparative to that in the normal BG 11 medium. Expand
Development of Botryococcus Seed Culture System for Future Mass Culture
TLDR
The BOT-22 strain of Botryococcus braunii was cultured under laboratory and outdoor conditions and maximum growth rates obtained using a tube bioreactor were two times higher than those obtained using 10L/30L scale cultures and a domeBioreactor. Expand

Botryococcus braunii an unusual hydrocarbon-producing alga
TLDR
Present considerations do not point optimistically to the widespread use of Botryococcus as a renewable fuel source, although a long-range potential for the production of specific industrial feedstocks may exist. Expand
Biosynthesis of unusual acyclic isoprenoids in the Alga Botryococcus braunii
TLDR
This study provides further evidence that the relatively slow growth of Botryococcus in culture may result, in part, from the diversion of a large proportion of reduced carbon into energetically expensive compounds and that the slower growth rate in the ‘resting state’ cannot be totally attributed to an impaired or intrinsically slow metabolism.

Nature and hydrocarbon content of blooms of the alga Botryococcus braunii occuring in Australian freshwater lakes

VARIABILITY OF CELL WALL STRUCTURE AND HYDROCARBON TYPE IN DIFFERENT STRAINS OF BOTRYOCOCCUS BRAUNII 1
TLDR
The existence of distinct strains of Botryococcus braunii, some synthesizing dienes, others botryococcenes, appears highly probable, although the general internal structure of the cells was rather constant. Expand

The biosynthesis of long-chain hydrocarbons in the green alga Botryococcus braunii
TLDR
The cultures were also shown to be unable, under usual growth conditions, to catabolize their own hydrocarbons, and this feature, along with the extracellular location of the main site of production, may account for the abnormally high content of hydroCarbons typical of B. braunii. Expand
Olefins of High Molecular Weight in Two Microscopic Algae
TLDR
The hydrocarbon composition of two algae, a golden-brown (Bot-ryococcus braunii) and a blue-green (Anacystis montana), has been investigated by gas chromatography-mass spectrometry and may be the precursors of the hydrocarbons in these formations. Expand
Sites of accumulation and composition of hydrocarbons in Botryococcus braunii
TLDR
Raman spectrometry and electron microscopy show that, in the hydrocarbon-rich alga Botryococcus braunii, hydrocarbons accumulate in two distinct sites; internally in cytoplasmic inclusions and externally in successive outer walls and derived globules, where they contain a sporopollenin-like compound.
