Botryococcane in a new class of Australian non-marine crude oils

A Review of Macromolecular Organic Compounds That Comprise Living Organisms and Their Role in Kerogen, Coal, and Petroleum Formation

“…Botryococcenes probably exhibit a quite low resistance to diagenesis since a complete lack of botryococcane was noted in the bitumen of 12 torbanites, even when deposited under partly oxic conditions (Derenne et al,19S8b). This is also consistent with the occurrence of botryococcane in a very limited number of oils and bitumens while Botryococcus remains are widespread in numerous kerogens (Moldowan and Seifert, 19S0;Seifert and Moldowan, 1981;Brassell et al, 1986;McKirdy et al, 1986). In addition to selectively preserved algaenan, the coorongite is composed of chemically labile constituents (ca.…”

Lipids and Macromolecular Lipids of the Hydrocarbon-rich Microalga Botryococcus braunii. Chemical Structure and Biosynthesis. Geochemical and Biotechnological Importance

“…The presence of botryococcane in the above oils revealed a substantial contribution of the B race of B. braunii to the formation of the source rocks from which these oils were derived. C 34 botryococcane was also identified, in high concentrations, in Australian coastal bitumens (99). C31 and C33 botryococcanes dominated the aliphatic hydrocarbon fraction isolated from the extract of the Maoming oil shale of China (100).…”

Systems and economic analysis of microalgae ponds for conversion of CO{sub 2} to biomass. Final report

“…As stated, its claim to fame is the ability to produce large amounts of pure hydrocarbons, which appear as oil droplets excreted by the cells. Its other claim to fame is that hydrocarbons characteristic of this alga are found in association with oils from a variety of geological sources with its characteristic hydrocarbons (for example botryococcene) found as major ( > 1%) components in many oil deposits, both ancient and modem, making this the largest of any biomarker in petroleum (see McKirdy et al, 1986, and references therein).…”
