Abstract
Official abstract text for this publication.
Provision of a novel strain belonging to Botryococcus braunii , capable of growth under a wide range of culturing conditions, having a high produced hydrocarbon content, and having high purity of the target hydrocarbon.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a hydrocarbon from a strain belonging to Botryococcus braunii race-B that produces a hydrocarbon of the molecular formula C 34 H 58 at 60% by weight or greater with respect to the total produced hydrocarbons, comprising the steps of culturing said strain at a temperature of 35° C. to 50° C., and then extracting said hydrocarbon from said cultured strain with at least one organic solvent, wherein said strain is Botryococcus braunii tsukuba-1 (deposit number: FERM ABP-11441). 2. The method according to claim 1 , wherein the culturing is conducted at a temperature of 39° C. 3. The method according to claim 1 , wherein the culturing is conducted at a temperature of 36° C. 4. The method according to claim 1 , wherein the hydrocarbon of the molecular formula C 34 H 58 has the structure of the following Formula (I): 5. The method of claim 1 , wherein the culturing is conducted at a temperature of 35° C. to 40° C. 6. The method of claim 5 , wherein the culturing is conducted at a temperature of 35° C. to 36° C. 7. The method of claim 1 , wherein the at least one organic solvent is n-hexane. 8. The method of claim 1 , wherein the at least one organic solvent is a mixture of chloroform and methanol. 9. The method of claim 8 , wherein the at least one organic solvent is a 1:1 mixture of chloroform and methanol. 10. The method of claim 8 , wherein the at least one organic solvent is a 1:2 mixture of chloroform and methanol. 11. The method of claim 8 , wherein the hydrocarbon extracted is concentrated to dryness under a nitrogen stream and again extracted with n-hexane. 12. The method of claim 1 , wherein the culturing is conducted for a period of 1 to 5 months. 13. The method of claim 12 , wherein the culturing is conducted for a period of 1 to 3 months.
