Abstract

The invention discloses high-oil-yield scenedesmus SDEC-13 and a culture method and an application thereof. An algal strain disclosed by the invention is scenedesmus quadricauda SDEC-13, and can grow by virtue of high-concentration CO2; a gene sequence is submitted to a GenBank database; the number is KF999644; the algal specie is preserved at the China Center for Type Culture Collection in November 2014; and the preservation number is CCTCC M4014498. According to the algal specie disclosed by the invention, high-concentration CO2 in the waste gas can be utilized to reduce the culture cost. The scenedesmus disclosed by the invention is rich in excellent oil; the total oil content can reach 27.2% of dry weight; the saturated fatty acid content in fatty acid can be up to 82.87%; the content of the fatty acid of which the carbon chain length is 16-18 in fatty acid components can be up to over 98%; and the scenedesmus is suitable for being used as a raw material for producing biodiesel.

Description

technical field

[0001] The invention belongs to the field of microalgae biotechnology, in particular to a high-yielding Scenedesmus SDEC-13 and its cultivation method and application. Background technique

[0002] Energy shortage and excessive emission of carbon dioxide are two prominent environmental problems in the world today.

[0003] With the rapid development of society and economy, the consumption of primary energy continues to increase, and the energy gap is expanding year by year. At the same time, due to the burning of fossil fuels, excessive carbon dioxide is emitted into the atmosphere, leading to the global greenhouse effect. As a renewable energy source, biodiesel has the potential to solve both problems. Algae is a very efficient feedstock for biodiesel production. Its advantages are: 1. The growth rate is fast, and it can be harvested in more than ten days; 2. It can be cultivated in wastewater that cannot grow food, and does not occupy the area of ​​arable...
