Microalgae Aurantiochytrium sp. LA3 (KCTC12685BP) and Method for Preparing Bio-Oil Using the Same

Abstract

Provided herein are microalgae of a Thraustochytrid and a method for preparing bio-oil using the same, and more particularly, Aurantiochytrium sp. LA3 (KCTC12685BP) having bio-oil producibility, and a method of preparing bio-oil, particularly bio-oil having a content of omega-3 unsaturated fatty acids of 30% by weight or more based on total fatty acids, characterized by culturing the microalgae. The microalgae Aurantiochytrium sp. LA3 (KCTC12685BP) described herein has a rapid sugar consumption rate when being cultured using glucose as a carbon source, has a high oil content, allows cells to be cultured at a high concentration, and allows oil to be obtained in high productivity and a high yield, and thus, may produce bio-oil more economically and environmentally friendly.

1 . A microalgae  Aurantiochytrium  sp. LA3 (KCTC 12685BP) having bio-oil producibility. 
     
     
         2 . The microalgae of  claim 1 , wherein the  Aurantiochytrium  sp. LA3 (KCTC 12685BP) has a DNA sequence of a 18S rRNA gene of SEQ ID NO: 1. 
     
     
         3 . The microalgae of  claim 1 , wherein bio-oil prepared from the microalgae has an omega-3 unsaturated fatty acid content of 30 wt % or more based on total fatty acids.
