Title:
NOVEL MICROORGANISM OF RHIZOBIALES SP. KB 10 HAVING PROPERTIES OF STIMULATING GROWTH AND INCREASING FATTY ACID CONTENT OF BOTRYOCOCCUS BRAUNII
Document Type and Number:
WIPO Patent Application WO/2013/133526
Kind Code:
A1
Abstract:
The present invention relates to a Rhizobiales sp. KB 10 strain having the functions of simultaneously stimulating the growth of Botryococcus braunii, which is a biodiesel-producing alga, and enhancing the ability thereof to produce biodiesel, and more particularly, to a Rhizobiales sp. KB 10 strain, a novel strain, having the functions of stimulating the growth of Botryococcus braunii, which is used for producing biodiesel, and maximally increasing C18 oleic acid content by up to 9 times more, which corresponds to a high-quality biodiesel component. By using leguminous bacteria such as Rhizobiales, the poor cell growth of Botryococcus braunii can be effectively stimulated while simultaneously maximally increasing oleic acid content, which is a high-quality biodiesel component. Also, the problem of contamination caused by other microorganisms during an open culture process for producing biodiesel can be readily solved by using a mixed culture of the bacteria.
