Title: Innovations of Keishi Sakaguchi in Microbial Oil Production

Introduction

Keishi Sakaguchi, an accomplished inventor located in Fukuoka, Japan, has made significant contributions to the field of microbial oil production. With a total of four patents to his name, his work focuses on harnessing the potential of stramenopiles for the generation of fatty acids beneficial for various applications.

Latest Patents

One of his latest patents is titled "Microbial oil containing fatty acids obtained from stramenopile and method of producing the same." This innovative approach involves obtaining microbial oil from Labyrinthulomycetes by disrupting or inhibiting the expression of a gene responsible for fatty acid biosynthesis, leading to a high accumulation of fatty acids. The resulting microbial oil boasts an impressive composition, typically containing:

(a) 1.5% or more of arachidonic acid (AA),

(b) 0.2% or more of dihomo-γ-linolenic acid (DGLA),

(c) 0.04% or more of eicosatetraenoic acid (ETA),

(d) 3.8% or more of eicosapentaenoic acid (EPA),

(e) 13.7% or less of n-6 docosapentaenoic acid (n-6DPA), and

(f) 43.9% or less of docosahexaenoic acid (DHA).

Additionally, his work on "Microbial oil extracted from stramenopiles" focuses on the extraction of oil from stramenopiles that have been transformed with a gene associated with fatty acid synthesis. This innovative microbial oil meets specific requirements, including limits on arachidonic acid, DPA, ETA, EPA, and DHA content.
